What is the difference between gravitational potential energy and weight?
A weight lifted vertically to acquire gravitational potential energy. A weight lifted vertically to acquire gravitational potential energy. If the force were to be removed, the object would fall back down to the ground and the gravitational potential energy would be transferred to kinetic energy of the falling object.
What is the difference between potential energy and gravitational potential energy?
Potential energy is energy that is stored in an object or substance. Gravitational potential energy is energy in an object that is held in a vertical position.
What is the relationship between the mass of an object and gravitational potential energy?
Gravitational potential energy at large distances is directly proportional to the masses and inversely proportional to the distance between them. The gravitational potential energy increases as r increases.
What is the difference between gravitational potential energy and elastic potential energy give one example for each?
Example: (i) Gravitational potential energy – A book kept on a table possesses gravitational potential energy because of its position above the ground. (ii) Elastic potential energy – The stretched rubber string of a catapult possesses elastic potential energy because of the change in shape of the string.
How is gravitational potential difference calculated?
The gravitational potential of a point is equal to the potential energy that a unit mass would have at that point. It is given by V, equals, start fraction, U, divided by, m 2, end fraction,V=m2U where U,U is the potential energy of a mass m 2,m2 at that point.
What is gravity potential difference?
Gravitational potential difference between two points is defined as the amount of work done in moving unit mass from one point to another point against the gravitational force of attraction.
What is the relationship of mass weight and height to the PE of an object?
For the gravitational force the formula is P.E. = mgh, where m is the mass in kilograms, g is the acceleration due to gravity (9.8 m / s2 at the surface of the earth) and h is the height in meters.
