Why do people put sand under a car wheel when it is spinning on ice?

• to increase kinetic energy

• to melt the ice

• to increase the friction between the tires and the ice

• to increase the speed the wheel spins

This force makes objects slow down or stop and is caused by objects rubbing together. What is this force called?

• drag

• gravity

• magnetism

• friction

The force of repulsion or attraction between poles of magnets is called ---

• drag

• gravity

• magnetism

• friction

objects can be made to move from on position to another. They can be made to move faster, slower, change direction, or stop. What causes this movement?

• directions cause motion

• speed causes motion

• height causes motion

• forces cause motion

How is an object's position determined?

• by its speed compared to another object

• by its location to another object

• by its force compared to another object

• by its temperature compared to another object

Direction of motion is the ---

• path on which an object is moving

• speed that an object is moving

• force that an object is moving

• incline of a moving object

A force is applied directly below a stationary object, such as a tennis ball, the object will move in which direction?

• up

• down

• right

• left
