Students used a spring scale to pull 3 different loads across a single surface. Each load had a different mass. They recorded the force (N) needed to pull each load across the surface. Which question were the students most likely trying to answer with this investigation?

• Which surface required the most force to pull the load?

• Does the mass of the load affect the force required to pull the load?

• How can the mass of the load change?

• Does the surface change the mass of the load?

A student wearing skates rolls down a ramp. What force causes the student to slow down and stop rolling?

• gravity, which acts against the direction of motion

• friction, which acts against the direction of motion

• magnetism, which acts against the direction of motion

• mass, which increases with motion
