What happens to the gravitational potential energy of an object when it moves up?

Since the gravitational potential energy of an object is directly proportional to its height above the zero position, a doubling of the height will result in a doubling of the gravitational potential energy. A tripling of the height will result in a tripling of the gravitational potential energy.

What happens to the gravitational potential energy of an object when it moves down?

If an object falls from one point to another point inside a gravitational field, the force of gravity will do positive work on the object, and the gravitational potential energy will decrease by the same amount. When the book hits the floor, this kinetic energy is converted into heat and sound by the impact.

What factor s affect the potential energy?

Gravitational Potential Energy is determined by three factors: mass, gravity, and height. All three factors are directly proportional to energy.

What affects the gravitational potential energy of an object?

How does the position of the object affects the potential energy of the object?

Where and how does the water get its gravitational potential energy?

The water behind a hydroelectric dam stores gravitational potential energy since it is at a higher level than the water on the other side of the dam. As the water falls, this potential energy is converted into kinetic energy, which turns turbines to generate electricity.

When water reaches the top of the waterfall does it have kinetic energy potential energy or both?

GPE = mass * g * height At the top of the waterfall, the water is higher in the gravitational field of the Earth and has gravitational potential energy. When it falls, the potential energy turns into kinetic energy. So energy is not created, it was there at the beginning, stored as potential energy.

What happens to the gravitational potential energy when an object falls?

gravitational potential energy is being transformed to kinetic energy as the object falls. On the other hand, if an object is thrown upwards, it gains height and loses speed, thus increasing its gravitational potential energy and decreasing its kinetic energy. In this case it is

What happens to kinetic energy when an object is thrown upwards?

On the other hand, if an object is thrown upwards, it gains height and loses speed, thus increasing its gravitational potential energy and decreasing its kinetic energy. In this case it is the kinetic energy which is being transformed into gravitational potential energy.

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.

Why is the gravitational potential energy negative at infinity?

We place the zero point of gravitational potential energy at a distance of infinity. This makes all values of the gravitational potential energy negative. It turns out that it makes sense to do this because as the distance becomes large, the gravitational force tends rapidly towards zero.
