Does more weight mean more gravitational potential energy?
The gravitational potential energy of an object depends on the mass of objects, and how far away they are from each other. More massive objects have more gravitational pull. (Remember that just because something is bigger, doesn’t mean it has more mass!)
How does weight affect gravitational potential energy?
Gravitational potential energy depends on an object’s weight and its height above the ground (GPE = weight x height). Elastic potential energy is due to an object’s shape. It results when an elastic object is stretched or compressed. The more it is stretched or compressed, the greater its elastic potential energy is.
Does more mass equal more potential energy?
The amount of gravitational potential energy an object has depends on its height and mass. The heavier the object and the higher it is above the ground, the more gravitational potential energy it holds.
How is gravitational potential energy defined?
Gravitational potential energy is the energy stored in an object as the result of its vertical position or height. The energy is stored as the result of the gravitational attraction of the Earth for the object.
What is the gravitational potential energy of gravity?
The force of gravity is no exception. Gravitational potential energy is usually given the symbol . It represents the potential an object has to do work as a result of being located at a particular position in a gravitational field. Consider an object of mass being lifted through a height against the force of gravity as shown below.
What happens to potential energy when a weight is lifted vertically?
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 happens to the gravitational potential energy when a ball is dropped?
The gravitational potential energy is converted to kinetic energy. Gravitational potential energy at the top = kinetic energy at the bottom A ball of mass 0.4 kg is lifted to a height of 2.5 m. It is then dropped, from rest. The ball returns to the ground with a speed of 7.1 m/s.
How many joules of potential energy does a 3kg object have?
In this example, a 3 kilogram mass, at a height of 5 meters, while acted on by Earth’s gravity would have 147.15 Joules of potential energy, PE = 3kg * 9.81 m/s 2 * 5m = 147.15 J. 9.81 meters per second squared (or more accurately 9.80665 m/s 2) is widely accepted among scientists as a working average value for Earth’s gravitational pull.
