What is the Law of Conservation of Energy?

Back

The Law of Conservation of Energy states that energy cannot be created or destroyed, only transformed from one form to another.

What is kinetic energy?

Back

Kinetic energy is the energy an object possesses due to its motion, calculated as KE = 1/2 mv², where m is mass and v is velocity.

What is gravitational potential energy?

Back

Gravitational potential energy is the energy an object has due to its position relative to the Earth's surface, calculated as PE = mgh, where m is mass, g is the acceleration due to gravity, and h is height.

What is elastic potential energy?

Back

Elastic potential energy is the energy stored in elastic materials as the result of their stretching or compressing.

Front

What is the difference between kinetic energy and potential energy?

Back

Kinetic energy is energy of motion, while potential energy is stored energy based on an object's position or state.

What factors affect gravitational potential energy?

Back

Gravitational potential energy depends on the mass of the object, the height above the ground, and the acceleration due to gravity.

What is an example of energy transformation?

Back

When a bow is drawn, elastic potential energy is stored; when released, it transforms into kinetic energy of the arrow.
