Carol was playing with some rubber bands outside. She was trying to release the rubber band from her fingers to see how far it would travel. What could Carol do to increase the distance the rubber band will travel?

• tie a knot in the rubber band

• cut the rubber band in half to make it longer

• stretch the rubber band between her fingers

What happens to the distance a car travels as you increase the height of the ramp?

• the car travels farther due to the potential energy that is increased by the height of the ramp

• the car travels at a slow speed down the ramp due to the car being red

• the car travels farther down the ramp due to the wheels on the car

• the car travels farther down the ramp due to the temperature of the car
