SchoolN. Motion KE/PE Flashcard

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 of an object due to its position or state. It can be gravitational, elastic, or chemical.

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

How does kinetic energy change when an object is in motion?

Back

Kinetic energy increases as the speed of the object increases, and decreases as the object slows down.

Front

What happens to potential energy as a pendulum swings from its highest point?

Back

As a pendulum swings down from its highest point, its potential energy decreases while its kinetic energy increases.

Front

What is the principle of conservation of energy?

Back

The principle of conservation of energy states that energy cannot be created or destroyed, only transformed from one form to another.

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

What happens to the energy of a rock that tumbles down a hill?

Back

The stored potential energy of the rock is converted into kinetic energy as it moves downhill.

Front

How can a diver gain potential energy?

Back

A diver can gain potential energy by climbing higher, such as going up the ladder of a diving board.

Front

What is the relationship between kinetic and potential energy in a swinging swing?

Back

In a swinging swing, potential energy is converted to kinetic energy as the swing moves downward and vice versa as it moves upward.
