Forces Review 2

A student sets up an experiment using the ramp below to test how far a car would travel after leaving a ramp.

What force is responsible for causing the car to stop?

• Gravity

• Friction

• Magnetism

• None of the above

Students performed an experiment in which they rolled toy cars with different masses down the same ramp three times.

Which testable question could the students be investigating?

• Does the surface of a ramp affect the distance a toy car travels?

• How is a toy car affected by the attraction of magnets?

• Does the mass of a toy car affect the distance it travels?

• How does ramp height affect the distance a toy car travels?

Students set up an experiment where they rolled some objects down a ramp. They used the table for recording their results.

Based on the table, which hypothesis were the students most likely testing?

• The ramp material will affect the rate of speed of the object.

• The more massive the object, the faster the travel time.

• Round objects will travel down the ramp the fastest.

• If the ramp is a greater length, then the object will travel more slowly.

Students wanted to investigate if water balloons dropped from greater heights made larger splatters. This experiment is an investigation of the effect of which of the following?

• Temperature

• Sound

• Gravity

• Magnetism
