why is gravitational potential energy somtimes called 'uphill energy'
Potential energy is used when travelling uphill. As you move higher in altitude, you are increasing your gravitational potential energy. This energy comes from the work done against gravity to move your body upwards.
When riding a bicycle uphill, the energy conversion involves converting chemical energy from food consumed into kinetic energy to pedal the bike uphill against gravity. When riding downhill, potential energy is converted into kinetic energy as the bike accelerates due to gravity. Some energy is lost as heat and air resistance during both uphill and downhill cycling.
Gravitational energy is when an object has more potential energy because of its higher or up hill position. An object rolling down a steep hill will have more energy than one from a lower position.
Thermal energy can be converted into gravitational potential energy through a process involving the use of a heat engine to lift an object against gravity, thereby storing potential energy. An example could be using a heated fluid to drive a turbine that lifts water uphill, converting thermal energy into gravitational potential energy in the water's elevated position.
Yes, pulling a wagon uphill requires exerting force against gravity, which increases the potential energy of the wagon as it gains height. This potential energy can then be converted back to kinetic energy as the wagon moves downhill.
They could in theory.
Potential energy is stored in your body as you walk uphill. As you move against gravity, your body gains potential energy based on your height above the ground. This potential energy can be released as kinetic energy when you go back downhill.
A ball travels faster uphill than downhill due to potential energy being converted to kinetic energy as it rolls downhill.
When driving uphill, gravity acts against your motion, decreasing your kinetic energy. When driving downhill, gravity acts in the direction of motion, increasing your kinetic energy.

A ball slowing down as it rolls up a hill is an example of kinetic energy being converted into potential energy. As the ball moves uphill, it loses kinetic energy which is converted into gravitational potential energy due to its increased height. This conversion causes the ball to slow down.
Potential energy is stored in the cyclist's muscles while biking up a hill. As the cyclist pedals uphill, their muscular effort creates potential energy that is then converted into kinetic energy as they move uphill.
