What does the static coefficient represent?
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?
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?
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
