Kinetic and Potential Energy Practice

Front

What is kinetic energy?

Back

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

Front

What is potential energy?

Back

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

Front

At which point in a pendulum's swing is kinetic energy highest?

Back

At point 3, where the pendulum is at its lowest point.

Front

At which point in a pendulum's swing is potential energy highest?

Back

At point 1, where the pendulum is at its highest point.

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 type of energy does a roller coaster have at the top of a hill?

Back

High potential energy.

Front

What type of energy does a moving car have?

Back

Kinetic energy.

Front

What is the formula for kinetic energy?

Back

Kinetic energy (KE) = 1/2 mv², where m is mass and v is velocity.

Front

What is the formula for potential energy?

Back

Potential energy (PE) = mgh, where m is mass, g is acceleration due to gravity, and h is height.

Front

What is the relationship between kinetic and potential energy in a closed system?

Back

In a closed system, the total mechanical energy (kinetic + potential) remains constant.
