Questions and Answers

What does the static coefficient represent?

  • The coefficient related to the block's weight
  • The coefficient used when the block is in motion
  • The coefficient used when the block is stationary (correct)
  • The coefficient related to the direction of the force

    • How is the coefficient of static friction, μs, experimentally determined?

  • By measuring the displacement of the block
  • By measuring the velocity of the block when it starts moving
  • By carefully measuring the force at the point where the block is on the verge of moving (correct)
  • By calculating the acceleration of the block

    • What does F = -μsN represent in the context of frictional force?

  • $F = -μsN$ represents the net force acting on the block
  • $F = -μsN$ represents the frictional force required to reach the point where the block is on the verge of moving (correct)
  • $F = -μsN$ represents the weight of the block
  • $F = -μsN$ represents the force pushing the block
