Week 16 - Potential and Kinetic Energy

Front

What type of energy is stored when you compress a spring?

Back

Elastic energy.

Front

What is the relationship between speed and kinetic energy?

Back

The faster an object moves, the more kinetic energy it has.

Front

What does the law of conservation of energy state?

Back

Energy cannot be created or destroyed, only converted from one form to another.

Front

If two vehicles are moving at the same speed, which one has the greatest kinetic energy?

Back

The vehicle with the greatest mass.

Front

What is kinetic energy?

Back

The energy an object possesses due to its motion.

Front

What is potential energy?

Back

The stored energy in an object due to its position or state.

Front

What happens to potential energy as an object falls?

Back

It is converted into kinetic energy.

Front

What is the formula for calculating kinetic energy?

Back

KE = 1/2 mv², where m is mass and v is velocity.

Front

What is the formula for calculating potential energy?

Back

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

Front

What type of energy does a stretched rubber band have?

Back

Elastic potential energy.
