Potential energy is involved in each of these events. match each event with its source of potential energy. a trampoline expands and contracts from the weight of children a chemical substance reacts with water to give off heat a skydiver jumps from a plane and free-falls toward the ground gravitational potential energy arrowright elastic potential energy arrowright chemical potential energy arrowright
2.is chemical potential
4.is chemical potential
5. is elastic potential
2. Gas in lawn mower: chemical potential energy
3. Nut on tree: gravitational potential energy
4. Apples: chemical potential energy
5. Arrow: elastic potential energy
kenetic energy is how roller coasters work
Explanation: my 5th grade teacher told me
Thermal and Elastic
1. Emma standing on top of mountain
Since she is at the rest position and at some height from the ground so here energy is due to gravitational potential energy
So we have
gravitational potential energy
2. Emma jumping down from mountain top
Due to free fall Emma will start moving with some speed in downwards direction so here we have
3. tension in rope at Emma’s lowest position
Due to stretch in the rope here position come to the lowest end and speed comes to zero so whole energy is converted into elastic potential energy
elastic potential energy
4. Emma bouncing back
Due to bouncing back she will again have its kinetic energy with some speed upwards
B is the answer to this question. Hope this helps!
chemical potential energy
Elastic potential energy. b
human potential energy
It is given that, before a ball rolls down a hill, it has gravitational potential energy.
Before a rubber ball bounces away from a surface, it has elastic potential energy.
Human potential energy allows us to throw a ball. While throwing a ball, we have to apply some force by our muscles in order to done some work.Also, we know that the capacity to do work is called energy.
Hence, the correct option is (D) " human potential energy ".
I think Kinetic energy forms Motion energy and Potential energy forms Gravitational Potential energy.
