What is the coefficient of friction between the coin and turntable?

The coefficient of static friction between a small coin and the surface of a turntable is 0.30 .

What is the coefficient of static friction between?

The coefficient of static friction is the ratio of the maximum static friction force (F) between the surfaces in contact before movement commences to the normal (N) force.

What is the coefficient of static friction between the ground and the box?

0.30
The coefficient of static friction between the box and the floor is 0.30.

What force accelerates the coin?

static friction
Reasoning: When the coin is at rest relative to the rotating turntable, the force of static friction between the coin and the turntable provides the centripetal acceleration.

What does a lower coefficient of friction mean?

The coefficient of friction, µ, is a measure of the amount of friction existing between two surfaces. A low value of coefficient of friction indicates that the force required for sliding to occur is less than the force required when the coefficient of friction is high.

What is coefficient friction?

coefficient of friction, ratio of the frictional force resisting the motion of two surfaces in contact to the normal force pressing the two surfaces together. It is usually symbolized by the Greek letter mu (μ). Mathematically, μ = F/N, where F is the frictional force and N is the normal force.

What is the coefficient of static friction between paper and paper?

While the coefficient of friction at zero moisture ratio varies bet- ween 0.1 and 0.6 the slopes for the uncoated papers only vary between 1.6 and 2.7.

How do you find the coefficient of static and kinetic friction?

The formula is µ = f / N, where µ is the coefficient of friction, f is the amount of force that resists motion, and N is the normal force.

What is the coefficient of friction between the box and the table?

0.20
The coefficient of sliding friction between box A and the table is 0.20.

Does static friction provides the centripetal force for an object resting on a spinning turntable?

Solution: Reasoning: When the coin is at rest relative to the rotating turntable, the force of static friction between the coin and the turntable provides the centripetal acceleration.

How does friction affect a coin on a turntable?

The static friction between the coin and the turntable is a force threshold. The magnitude of the coin’s velocity becomes high enough as the disc spins faster that eventually the centripetal force (the force required to keep the coin from flying away) becomes greater than the static friction between the two surfaces can resist.

How does the speed of a coin affect the friction?

The magnitude of the coin’s velocity becomes high enough as the disc spins faster that eventually the centripetal force (the force required to keep the coin from flying away) becomes greater than the static friction between the two surfaces can resist.

How does the centripetal force change with the speed of a coin?

From this equation you can see that, as the magnitude of the coin’s velocity increases (i.e., as the turntable spins faster), the magnitude of the centripetal force increases. The centripetal force is the amount of force required to keep the object in circular motion around the center of the turntable at a velocity, v.

How do you place a coin on a turn table?

A coin is placed 1 2.0 c m from the axis of a rotating turn table of variable speed. When the speed of the turn table is slowly increased, the coin remains fixed on the table until a rate of 35.0 r p m is reached, at which point the coin slides off.
