Friction problem 1

Determine whether the statements are correct:

  • Frictional force acts in the direction of the body's motion.

  • Friction is greater if the body mass is greater and if the contact surface between the body and the ground is rougher.

  • Friction is greater at higher body speeds.

  • Friction is independent of the size of the contact area between the body and the ground.

  • Friction is low during skating because the ice is smooth.

  • When a boatman paddles on water, the motion is hindered by friction between the boat and the water.
