Is a trampoline a waste of thermal energy?
A trampoline itself does not generate or waste thermal energy. However, when people jump on a trampoline, some energy is converted to heat due to friction between the trampoline material and the person jumping. This is a very small amount of thermal energy in comparison to the movement energy expended.
What causes an object to heat up or cool down?
An object heats up when it absorbs heat energy from its surroundings, and cools down when it releases heat energy to its surroundings. This process is known as thermal energy transfer.
Which type of energy does a person have when jumping on the trampoline?
When a person is jumping on a trampoline, they have potential energy at the highest point of their jump, which is converted to kinetic energy when they are moving up and down. This energy conversion continues as they jump, with potential energy being converted to kinetic energy and back again.
Where does thermal energy come from when a fire fighter slides down a pole?
The thermal energy comes from the friction between the firefighter's hands and the pole as they slide down quickly. This friction creates heat due to the resistance between the surfaces in contact, which warms up the pole.
What happens to thermal energy if the molicules speed up?
If molecules speed up, they gain kinetic energy which increases the thermal energy of the substance. This causes the temperature of the substance to rise since thermal energy is directly related to the average kinetic energy of the molecules.
How do rabbit used energy?
Rabbits use up energy by running/hopping around and jumping up and down.
What do you call energy that heats things up and cools things down?
Thermal energy

How does the phrase jumping up and down function in the following sentence Jumping up and down is a bad idea if you have just eaten chili dogs?
In the sentence Jumping up and down is a bad idea if you have just eaten chili dogs., the phrase jumping up and downis the subject.

How do cars use thermal energy?
Internal combustion engines use the oxidation of vaporized fuel to release thermal energy. This energy causes the gases present to expand rapidly, and this expansion is converted to mechanical energy by the pistons as they move up and down on the camshaft.
Does a gas lose or gain thermal energy in condensation?
The gas begins to cool down, and lose thermal energy, and moves up in the ladder of the 3 states of matter. Gasses condense into liquids, liquids turn into solids. The higher up you go, the less thermal energy the object has.
Does jumping up and down make you taller?
no.
What energy transformation occurs when jumping on a trampoline?
When jumping on a trampoline, the potential energy stored in your muscles is transformed into kinetic energy as you leave the trampoline surface. As you reach the apex of your jump, the kinetic energy is converted back into potential energy due to your change in height. This cycle of energy transformation continues as you bounce up and down on the trampoline.
