Energy Concepts Flashcard

Front

What is potential energy?

Back

Potential energy is the energy of an object due to its position or configuration.

Front

What is kinetic energy?

Back

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

Front

How are potential and kinetic energy related during the fall of an object?

Back

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

Front

What are the two factors that affect kinetic energy?

Back

The two factors that affect kinetic energy are mass and velocity.

Front

What is the formula for kinetic energy?

Back

The formula for kinetic energy is KE = 1/2 mv², where m is mass and v is velocity.

Front

What is the formula for potential energy?

Back

The formula for potential energy is PE = mgh, where m is mass, g is the acceleration due to gravity, and h is height.

Front

What happens to potential energy as an object is lifted higher?

Back

As an object is lifted higher, its potential energy increases.

Front

What happens to kinetic energy as an object slows down?

Back

As an object slows down, its kinetic energy decreases.

Front

What is an example of potential energy?

Back

An example of potential energy is a stretched rubber band or a rock at the top of a cliff.

Front

What is an example of kinetic energy?

Back

An example of kinetic energy is a moving car or a rolling ball.
