What force explains why it is easier to roll a ball on tile compared to carpet?

• Normal force

• Gravity

• Applied force

• Friction

Sam is helping her grandparents move. As she moves the couch on the floor, how is friction at work?

• Friction acts as the result of a push or pull and is the same as an applied force.

• Friction helps make it easier to move the couch.

• Friction opposes the applied forces and slows the couch as it contacts the carpet. It also creates a small amount of heat.

• • 
    

    Friction attracts the couch to the ground.
