Energy

Front

Energy due to motion is ____________ energy.

Back

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

Front

Which is the best example that something has kinetic energy? a. a car parked on a steep hill, b. a tennis ball rolling across the court, c. a picture hanging on the wall, d. a piece of coal before it's burned

Back

b. a tennis ball rolling across the court is an example of kinetic energy because it is in motion.

Front

Which bowling ball has LESS kinetic energy? 8 m/s, 10 m/s, they have the same amount of energy, none of these

Back

The bowling ball moving at 8 m/s has less kinetic energy than the one moving at 10 m/s.

Front

Which point has the greatest kinetic energy? A, B, C, none

Back

Point C has the greatest kinetic energy.

Front

At which point is potential energy greatest? W, X, Y, Z

Back

Potential energy is greatest at point W.

Front

What is potential energy?

Back

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

Front

What is the formula for kinetic energy?

Back

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

Front

What happens to kinetic energy if the speed of an object doubles?

Back

If the speed of an object doubles, its kinetic energy increases by a factor of four.

Front

What is the relationship between potential energy and height?

Back

Potential energy increases as the height of an object increases.

Front

What type of energy does a stretched rubber band have?

Back

A stretched rubber band has elastic potential energy.
