When dealing with the force of gravity between two objects, there are only two things that are important – mass, and distance . The force of gravity depends directly upon the masses of the two objects, and inversely on the square of the distance between them.
What are the factors affecting gravitational acceleration?
The acceleration due to gravity depends on the terms as the following: Mass of the body, Distance from the center of mass, Constant G i.e. Universal gravitational constant .
What are the factors which affect the force?
Force and Pressure | Short/Long Answer Questions
Solution: Factors on which moment of force depends are: (i) The magnitude of the force applied . (ii) The distance of line of action of the force from the axis of rotation.
What are the two main factors that affect gravity’s influence?
When dealing with the force of gravity between two objects, there are only two things that are important – mass, and distance . The force of gravity depends directly upon the masses of the two objects, and inversely on the square of the distance between them.
What three factors affect the pull of gravity?
The magnitude of this force depends upon the mass of each object and the distance between the centers of the two objects . Mathematically, we say the force of gravity depends directly upon the masses of the objects and inversely upon the distance between the objects squared.
What two qualities of objects does gravity depend on?
We also know that gravity depends on the mass of the object doing the pulling (in our case, the Earth), the mass of the object being pulled (such as a person), and the distance between the two.
Does gravitational acceleration depend on height?
The value of acceleration due to gravity ‘g’ is affected by
Altitude above the earth’s surface . Depth below the earth’s surface.
Where the acceleration due to gravity is maximum?
The value of acceleration due to gravity is maximum at the pole of the Earth .
Does the change of mass affect the acceleration due to gravity?
The mass does not affect the rate of acceleration . When the mass moves away from equilibrium the force of gravity does not change, only the spring force changes. and the height affect its acceleration due to gravity. Next, we have Newton’s Second Law, which is: F = ma or force is mass times acceleration.
What are 3 factors that affect friction?
The frictional force between two bodies depends mainly on three factors: (I) the adhesion between body surfaces (ii) roughness of the surface (iii) deformation of bodies .
What are the two main factors of frictional force?
- a) The materials that are in contact. The two materials and the nature of their surfaces. ...
- b) The force pushing the two surfaces together. Pushing the surfaces together causes the more of the asperities to come together and increases the surface area in contact with each other.
What are two factors which affect moment?
- M = the moment of the force in newton-metres, Nm.
- F = the force in newtons, N.
- d = the perpendicular distance from the line of action of the force to the pivot in metres, m.
What is gravity called?
gravity, also called gravitation , in mechanics, the universal force of attraction acting between all matter. ... On Earth all bodies have a weight, or downward force of gravity, proportional to their mass, which Earth’s mass exerts on them. Gravity is measured by the acceleration that it gives to freely falling objects.
What objects does gravity cause?
When objects fall to the ground, gravity causes them to accelerate . Acceleration is a change in velocity, and velocity, in turn, is a measure of the speed and direction of motion. Gravity causes an object to fall toward the ground at a faster and faster velocity the longer the object falls.
Is the force of gravity between two objects equal?
Since the gravitational force is directly proportional to the mass of both interacting objects , more massive objects will attract each other with a greater gravitational force. ... So as two objects are separated from each other, the force of gravitational attraction between them also decreases.
Which force is always attractive?
We all know that all the forces in nature exist in opposites, but gravitational force is the only force that always attracts every object and never reples any.
