What is the net force on a bathroom scale when a 110-pound person stands on it? Answer:
Zero
–the scale is at rest. The scale reads the support force, not the net force.
What is the net force that acts on a 10 N falling object when it encounters 4 N of air resistance 10 N of air resistance quizlet?
The force depends mostly on frontal area and speed. What is the net force that acts on a 10-N falling object when it encounters 4 N of air resistance? When it encounters10 N of air resistance? The net forces are
6 N and 0 N
, respectively.
When you stand at rest on a pair of bathroom scales the reading on each scale?
When you stand at rest on a pair of bathroom scales, the readings on the scales will alwaysSelected Answer:
add up to equal your weight
. The force of friction on a sliding object is 10 N.
What two forces are acting on a scale when you stand on it?
When you stand on a scale,
your weight pushes down on the scale
. This causes the scale pointer to point to your weight. At the same time, by Newton’s third law the scale pushes up on you with a force equal to your weight, as shown in Figure 19. This force balances the downward pull of gravity on you.
What is the net force on an object in either static or dynamic equilibrium?
What is the net force on an object in either static or dynamic equilibrium? The
net force is zero
.
What is the net force acting on an insect falling downward at constant velocity?
We are required to apply Newton’s law of motion to an object moving at a constant velocity. An object moving at constant velocity has zero acceleration. A)
zero
. The net force acting on an insect falling downward at constant velocity is zero.
When an apple that weighs 1 N is dropped and freely falls the net force on the apple is?
when an apple that weighs 1N is dropped and freely falls, the net force on the apple is
. 1N
.
What is the net force if it encounters 2 N of air resistance?
The net force acting on a falling 1kg ball if it encounters 2N of air resistance is
-8N
.
When the object encounters 10 N of air resistance the net force will be?
When the object encounters 10 N of air resistance, the net force will be ON Now the object’s
acceleration will become
As an object falls faster and faster through the air, its acceleration increases decreases).
What is the net force acting on a 1kg ball in free fall?
The net force acting on 1-kg ball in free fall is
9.8 N
. A body in free fall motion experiences free fall acceleration.
What are the two major types of force?
There are 2 types of forces,
contact forces
and act at a distance force. Every day you are using forces. Force is basically push and pull. When you push and pull you are applying a force to an object.
What is normal force formula?
| F_N Normal Force | m Mass | g Acceleration due to gravity |
|---|
Is normal force equal to weight?
The normal force is usually symbolized by N . In many cases the normal force is
simply equal to the weight of an object
, but that’s only when the normal force is the only thing counteracting the weight. … The normal force is the force that would be measured by a scale placed between the objects in contact.
Can a body in free fall be in equilibrium?
Yes! Such an equilibrium situation is called dynamic equilibrium . A body is said to be in equilibrium
if the net force acting on the body is zero
. By Newton’s second law, the acceleration of such objects will be zero.
What are the three conditions of equilibrium?
- The lines of action are coplanar (in the same plane)
- The lines of action are convergent (they cross at the same point)
- The vector sum of these forces is equal to the zero vector.
What is the net force on an object in either static?
In a static equilibrium, all the forces balance each other and object is either not moving or moving with uniform velocity and hence
net force is zero
.
