Which statement about friction is true? Friction prevents moving objects from stopping.
Friction increases the speed of objects in motion.
Friction acts in a direction opposite to an object’s motion.
Friction between objects depends solely on the types of surfaces involved.

1. True

Friction affects the relative motion between two surfaces in contact. Without friction, objects would not be able to move from a stationary position or stop when in motion.

2. False

Friction drag force causes objects to slow down as they move through a fluid, such as air or water. ... As an object's speed increases, the drag force from the fluid increases exponentially.

3. True

Frictional force offers the resistance to the applied force opposing its motion. Thus, it always acts in the direction opposite to that of the object in motion. If force is applied to the left, then friction acts in the right.

4. True

Friction depends partly on the smoothness of the contacting surfaces, a greater force being needed to move two surfaces past one another if they are rough than if they are smooth.
