What is stored energy that depends on an object's mass and position?
Potential energy.
Energy that has the ability to fall; this type of energy increases the higher up you go.
Gravitational Potential energy.
The ability to do work.
Energy
Stored energy due to being stretched or compressed.
Elastic
What is energy of motion that depends on an object's mass and speed?
Kinetic energy.
When a force is used to move an object through a distance.
The energy you require to function comes from food. What kind of energy is food?
Chemical
Vibrational movement through substances in waves.
A heavy object sitting on a table has this type of energy.
