Foss Gravity and Kinetic Energy

The ball in the diagram is held at the start position. When

released, it rolls down the ramp, travels up the other side to

position 1, then rolls back down the ramp.

Fill in the blanks to describe how potential and kinetic

energy is transferred in this situation.

At the start, the ball had ​ (a)   energy, which transferred to ​ (b)   energy as it rolled down the ramp. When the ball reached its highest point on the other side of the ramp, all its energy transferred to ​ (c)   energy.

Select all of the responses that are true about how the Earth causes changes in the ball's kinetic and potential energy.

• Earth's gravity is the force that gives the ball its potential energy.

• The farther from the Earth's surface, the greater the potential energy.

• Gravity increases the kinetic energy as the ball falls toward Earth.

A group of students is exploring how different variables affect the kinetic energy of a cart. They can change the ramp height with 1 - 3 blocks, and the cart can carry 1 to 3 marbles. Each time, they release the cart at the top of the ramp and measure its speed at the bottom. Which setup(s) (A, B, C, D) are set up properly to test only one variable?

• A

• B

• C

• D

• Doubling the mass of the bowling ball

• Doubling the speed of the bowling ball

• Doubling the volume of the bowling ball

How can we increase the gravitational potential energy of the car?

• Strap a boulder to the car so that it weighs more.

• Keep the length of the hill at 50 m but only 5 m tall.

• Take the interior out of the car so that the car has less mass.

• Keep the hill at 10 m tall but increase the length of the hill so that the car has farther to roll.
