I WONDER - What Is Friction? Me Pregunto - Qué Es La Fricción?

Friction occurs when two objects rub against each other, acting in the opposite direction of movement. The amount of friction depends on the materials and roughness of the surfaces involved. For instance, a bowling ball rolls further on a wooden floor than on a carpet due to less friction with wood compared to carpet.

What is the primary effect of friction on moving objects?

• It acts in the same direction as movement.

• It has no effect on movement.

• It speeds them up.

• It acts in the opposite direction of movement.

Which factor primarily determines the amount of friction between two surfaces?

• The size of the objects.

• The materials of the surfaces.

• The temperature of the environment.

• The color of the surfaces.

How does the roughness of a surface affect friction?

• Rougher surfaces decrease friction.

• Rougher surfaces increase friction.

• Roughness has no effect on friction.

• Rougher surfaces eliminate friction.

Why does a bowling ball roll further on a wooden floor than on a carpeted floor?

• The wooden floor is softer.

• The carpet is smoother.

• There is less friction on the wooden floor.

• The ball is lighter on the wooden floor.

What happens to the friction between a carpet and a ball compared to a wooden floor and a ball?

• Friction is eliminated on the carpet.

• There is more friction on the carpet.

• Friction is the same on both surfaces.

• There is more friction on the wooden floor.
