The kinetic energy of an object depends on the object's speed.
Energy is required to perform work. It provides us energy in form of chemical energy to perform work.
Human cells are able to take in these molecules and use their chemical potential energy.
Muscular energy is required to ride a bike.
During an energy transformation, the total amount of energy stays the same. So, when one type of energy decreases, at least one other type of energy will increase.
Muscle cells use chemical potential energy when they expand or contract to move parts of a person's body.
Ryan used his muscles to pedal up the hill, Ryan moved farther away from the center of Earth.
This is because during energy transformations, energy is converted between different types.
Increasing the distance between an object and Earth increases the gravitational potential energy stored between them.
An energy transformation converts one or more types of energy into other types of energy.
