Energy Flashcard 1

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 the speed at which it is moving.

Front

What is Potential Energy?

Back

Potential energy is the stored energy in an object due to its position or state. For example, a book on a desk has gravitational potential energy due to its height.

Front

How is Kinetic Energy calculated?

Back

Kinetic energy (KE) can be calculated using the formula: KE = 1/2 mv², where m is the mass of the object and v is its velocity.

Front

What happens to Potential Energy when an object falls?

Back

As an object falls, its potential energy decreases while its kinetic energy increases, but the total mechanical energy remains constant (ignoring air resistance).

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 an object with Kinetic Energy?

Back

A tennis ball rolling across the court is an example of an object with kinetic energy.

Front

What is an example of an object with Potential Energy?

Back

A car parked on a steep hill has potential energy due to its elevated position.

Front

What is the relationship between Kinetic and Potential Energy in a pendulum?

Back

In a pendulum, potential energy is highest at the highest point, and kinetic energy is highest at the lowest point of the swing.

Front

What does it mean to transfer energy?

Back

To transfer energy means to move energy from one object or system to another, such as when a moving ball hits a stationary ball.

Front

What is an example of energy transformation?

Back

When a book falls from a desk, its potential energy is transformed into kinetic energy as it moves downward.
