Hooke’s Law states that the force needed to compress or extend a spring is directly proportional to the distance you stretch it. As an equation, Hooke’s Law can be represented as F = kx , where F is the force we apply, k is the spring constant, and x is the extension of the material (typically in meters).
What force did you apply to compress the spring?
Gravity acts on you in the downward direction, and the spring in the scale pushes on you in the upward direction. The two forces have the same magnitude. Since the force the spring exerts on you is equal in magnitude to your weight, you exert a force equal to your weight on the spring, compressing it.
What is the force acting on a spring?
| Mass (kg) Force on Spring (N) Amount of Stretch (m) | 0.500 4.900 0.0199 |
|---|
What is an example of spring force?
When you jump on a trampoline , your body weight forces the trampoline downward, which further creates pressure in springs, generating a counterforce stored in springs that throws you upward.
How do you find the force?
The force formula is defined by Newton’s second law of motion: Force exerted by an object equals mass times acceleration of that object: F = m ⨉ a . To use this formula, you need to use SI units: Newtons for force, kilograms for mass, and meters per second squared for acceleration.
When a spring is compressed by applying a force on its kinetic energy gets stored in the spring?
This work is stored as elastic potential energy in the spring, as the result of their stretching or compressing.
What happens to a spring when force is applied?
If too much force is applied, one may stretch or compress a spring beyond a certain point that its deformation will occur . On subsequent release of the stress, the spring will return to a permanently deformed shape which will be different from its original shape.
What are examples of applied force?
An applied force is a force that is applied to an object by a person or another object. If a person is pushing a desk across the room , then there is an applied force acting upon the object. The applied force is the force exerted on the desk by the person.
What are 2 examples of forces?
- Electric force.
- Magnetic Force.
- Nuclear force.
- Frictional force.
- Normal force.
- Force of Gravity.
Is a spring force a contact force?
Contact forces are those that result from the interaction of objects in contact with each other . These include things like friction, air resistance, applied force, tension force, and spring force. Non-contact forces are those that result from the interaction of objects not in contact with each other.
How do you find force in physics?
Learning the Formula. Multiply mass times acceleration. The force (F) required to move an object of mass (m) with an acceleration (a) is given by the formula F = m x a. So, force = mass multiplied by acceleration .
How do you calculate compression force?

How do you test compression spring force?
- Measure the spring wire diameter, preferably to 3 decimal places for accuracy using calipers.
- Measure the outside diameter of the coils. ...
- Measure the length in its free condition (uncompressed).
- Count the number of coils. ...
- Note the winding direction of the coils.
What is spring compression?
Compression springs are coil springs that hold mechanical energy in their compressed states . When these springs experience a compression load, they compress and become shorter, capturing and storing significant potential force.
When a spring is compressed the energy changes from kinetic?
When a spring is compressed, the energy changes from kinetic to potential .
Is a compressed spring an example of kinetic energy?
After a mass attached to the free end of the spring is released, it oscillates back and forth. Its kinetic energy and potential energy stay constant. As the mass passes through the equilibrium point, the kinetic energy reaches its maximum.
When a spring is stretched the force changes the dash of the spring?
Explanation: when the spring is streched, the force change the, shape of the spring.
When a compressed spring is released?
If the spring is compressed, it will warm up slightly more . As each atom or ion is released from the crystals of metal, it will leave with a slightly higher energy because it is being released from a slightly higher energy state.
When force is applied to a spring the spring stretches if the applied force is doubled the potential energy of the spring will be?
5. If the stretch of a spring is doubled, the force it exerts is also doubled. By what factor does the potential energy increase? energy does not change .
Can a spring be over compressed?
When a spring has just the right dimensions and elasticity, it can safely be compressed all the way . Other designs may be so stiff or sturdy that if you try to do this, they will break.
What are the four main types of forces?
fundamental force, also called fundamental interaction, in physics, any of the four basic forces— gravitational, electromagnetic, strong, and weak —that govern how objects or particles interact and how certain particles decay. All the known forces of nature can be traced to these fundamental forces.
What is needed to apply force?
Necessary thing required to apply force is Frictional force . ... Friction provides the necessary grip to hold the objects, to move the objects, to stop the motion of object. Without friction Force, we can’t imagine to apply force.
What happens when we apply force?
Applied Force Affects Motion of Object . An applied force affects the motion of an object. An applied force can be a push, pull, or dragging on an object. The action from a force can cause an object to move or speed up (accelerate), to slow down (decelerate), to stop, or to change direction.
What is force and types of force?
Force and motion causes objects to move but also to stay still. Motion is simply a movement but needs a force to move. There are 2 types of forces, contact forces and act at a distance force. ... Force is basically push and pull . When you push and pull you are applying a force to an object.
What are the 3 types of contact forces?
- Frictional Force: Friction is a force exerted by a surface against the motion of a body across its surface. ...
- Applied Force: Force which is applied to an object by another object. ...
- Normal Force: The normal force is also called Support force.
What forces are non contact?
- Gravitational force.
- magnetic force.
- Electrostatics.
- The nuclear force – (there are two types of strong and weak nuclear force).
What kind of force is electrostatic force?
Electrostatic forces are non-contact forces ; they pull or push on objects without touching them. Rubbing some materials together can result in something called ‘charge’ being moved from one surface to the other. Charged objects pull on other uncharged objects and may either push or pull on other charged objects.
What type of force is sliding?
Sliding friction force opposes the movement between two contact surfaces that slide against each other. This force depends on the type of contact surfaces (materials and finishing level) and on the load applied in the direction perpendicular to the motion direction (Normal force).
What is force class 9th?
Force: It is a push or pull on an object that produces acceleration in the body on which it acts . ... (a) It can change the speed of a body. (b) It can change the direction of motion of a body.

Which formula represents force?
Newton’s Second Law
For a constant mass, force equals the mass times acceleration, i.e. F = m x a .
How do you find the force of friction?
- Choose the normal force acting between the object and the ground. Let’s assume a normal force of 250 N .
- Determine the friction coefficient. ...
- Multiply these values by each other: (250 N) * 0.13 = 32.5 N .
- You just found the force of friction!
How do you do net force?
Net force is the sum of all forces acting on an object. The net force can be calculated using Newton’s second law, which states that F = ma , where: F is the net force. m is the mass of the object.
How do you find net force with applied force and friction force?
When a force is applied to the body, not only is the applied force acting, there are many other forces like gravitational force Fg, frictional force Ff and the normal force that balances the other force. Therefore, the net force formula is given by, F Ne t = F a + F g + F f + FN.
Is Net force the same as applied force?
Since the net force is to the right (in the direction of the applied force), then the applied force must be greater than the friction force . The friction force can be determined using an understanding of net force as the vector sum of all the forces.
How did the force applied affect the acceleration of the box?
Newton’s second law of motion shows that there is a direct relationship between force and acceleration. The greater the force that is applied to an object of a given mass, the more the object will accelerate . For example, doubling the force on the object doubles its acceleration.
