What are two ways potential energy can be increased?

• By increasing the height of an object and by compressing a spring

• By decreasing the height of an object and by stretching a spring

• By increasing the speed of an object and by heating it

• By decreasing the mass of an object and by cooling it

What are two ways that kinetic energy can be increased?

• Increasing the mass and decreasing the velocity

• Decreasing the mass and increasing the velocity

• Increasing the mass and increasing the velocity

• Decreasing the mass and decreasing the velocity

The height of a ramp affects the speed of a ball rolling down it in terms of energy because:

• Higher ramps increase potential energy, leading to higher speed.

• Lower ramps increase potential energy, leading to higher speed.

• Height does not affect the speed of the ball.

• The speed of the ball is only affected by its mass.

When you bowl a strike, what happens to the mechanical energy in the bowling ball? Describe in terms of ENERGY TRANSFER.

• The mechanical energy is completely transferred to the pins.

• The mechanical energy is partially transferred to the pins and partially lost as heat and sound.

• The mechanical energy remains in the ball and is not transferred.

• The mechanical energy is converted entirely into sound energy.
