Students Experimenting with a Toy Car on a Smooth Wooden Ramp

Students are experimenting with a toy car on a smooth, wooden ramp. They apply force to the back of the car to push it down the ramp. The students measure how fast the car rolls down the ramp. If the students want to increase the speed of the car down the ramp, what should they do?

• decrease the angle of the ramp

• decrease the height of the ramp

• increase the force applied to the car

• increase the friction between the car and the ramp

A student sets a block at the top of a wooden ramp. The student pushes the block. As the block slides down the ramp, it slows down and then comes to a stop. What force causes the block to slow down?

• the force of gravity

• the force of friction

• the force of magnetism

• the force of the student's push

Which statement is a correct explanation for balanced forces acting on an object?

• The speed of the object decreases.

• The direction of the object changes.

• The speed of the object increases.

• The motion of the object stays the same.
