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 and speed of the object.

Front

What is potential energy?

Back

Potential energy is the stored energy in an object due to its position or state. It is often associated with height or condition.

Front

How does kinetic energy change when an object speeds up?

Back

As an object speeds up, its kinetic energy increases because kinetic energy is proportional to the square of its speed.

Front

How does potential energy change when an object is lifted?

Back

When an object is lifted, its potential energy increases because it is moving against the force of gravity.

Front

What happens to energy when a toy car goes down a hill?

Back

As the toy car goes down a hill, its potential energy decreases while its kinetic energy increases.

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

What is an example of energy transformation?

Back

An example of energy transformation is a roller coaster: potential energy at the top transforms into kinetic energy as it descends.

Front

What happens to the energy of a ball thrown into the air?

Back

As the ball rises, its kinetic energy decreases and potential energy increases until it reaches its highest point.

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 mass x gravity x height.

Front

How does energy change in a pendulum?

Back

In a pendulum, energy transforms between kinetic and potential energy as it swings back and forth.
