Energy Transformations

Front

What is kinetic energy?

Back

Kinetic energy is the energy an object possesses due to its motion. It depends on the mass of the object and its velocity.

Front

What is potential energy?

Back

Potential energy is the stored energy in an object due to its position or state. It can be gravitational, elastic, or chemical.

Front

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.

Front

Give an example of kinetic energy in everyday life.

Back

A moving car, a running dog, or a person riding a bicycle are all examples of kinetic energy.

Front

Give an example of potential energy in everyday life.

Back

A book on a shelf, a stretched rubber band, or water stored in a dam are examples of potential energy.

Front

What happens to potential energy as an object falls?

Back

As an object falls, its potential energy decreases while its kinetic energy increases.

Front

What is the relationship between kinetic and potential energy in a bouncing ball?

Back

In a bouncing ball, energy transforms from potential energy at the highest point to kinetic energy as it falls, and back to potential energy when it rises.

Front

What is gravitational potential energy?

Back

Gravitational potential energy is the potential energy an object has due to its height above the ground, calculated as PE = mgh (mass x gravity x height).

Front

How does energy transfer occur in a pendulum?

Back

In a pendulum, energy transfers between potential energy at the highest point and kinetic energy at the lowest point.

Front

What is mechanical energy?

Back

Mechanical energy is the sum of kinetic and potential energy in an object, representing the total energy of motion and position.
