Questions and Answers

What does the normal force exerted by a table do to a block resting on it?

  • It pushes the block sideways.
  • It creates friction with the block.
  • It opposes the weight of the block. (correct)
  • It pulls the block downward.

    • In the equation N - W = 0, what does N represent?

  • Normal force acting on the block (correct)
  • Frictional force against the block
  • Net force on the block
  • Weight of the table

    • What relationship does the normal force have with the weight of the block when at rest?

  • The normal force is irrelevant when the block is in motion.
  • The normal force is always less than the weight.
  • The normal force is equal to the weight of the block. (correct)
  • The normal force is always greater than the weight.

    • If the weight of a block is given by W = mg, what would be the equation for the normal force on that block?
