Mechanical Energy

Front

What is mechanical energy?

Back

Mechanical energy is the sum of potential energy and kinetic energy in an object.

Front

How do animals use mechanical energy?

Back

Animals use mechanical energy to do work, such as when birds fly or fish swim.

Front

What is kinetic energy?

Back

Kinetic energy is the energy of an object due to its motion.

Front

Which is an example of kinetic energy?

Back

A person walking is an example of kinetic energy.

Front

What is potential energy?

Back

Potential energy is the stored energy in an object due to its position or state.

Front

Is mechanical energy also potential energy?

Back

Yes, mechanical energy includes potential energy.

Front

Is mechanical energy also kinetic energy?

Back

Yes, mechanical energy includes kinetic energy.

Front

What happens to kinetic energy when an object speeds up?

Back

When an object speeds up, its kinetic energy increases.

Front

What happens to potential energy when an object is lifted higher?

Back

When an object is lifted higher, its potential energy increases.

Front

Can mechanical energy be converted from one form to another?

Back

Yes, mechanical energy can be converted between potential and kinetic energy.
