what direction is friction in circular motion?
444436
As we know that, friction is always in opposite direction to the motion at the contact surface. When a car is moving in circular motion, a centrifugal force is applied in the outward direction. Hence friction will act towards the center.

Uniform circular motion involves an object traveling a circular path at constant speed. Since the speed is constant, one would not usually think that the object is accelerating. However, the direction is constantly changing as the object traverses the circle. Thus, it is said to be accelerating.

The direction of the acceleration is inwards. The animation at the right depicts this by means of a vector arrow. The final motion characteristic for an object undergoing uniform circular motion is the net force. The net force acting upon such an object is directed towards the center of the circle.

In uniform circular motion, only the direction of the velocity is changing, because the force is at right angles to the movement. Since the speed (i.e. the magnitude of the velocity) is constant, no work is being done and the energy remains constant.

Friction is the force that opposes motion between any surfaces that are in contact. There are four types of friction: static, sliding, rolling, and fluid friction. Static, sliding, and rolling friction occur between solid surfaces. Fluid friction occurs in liquids and gases.

An object undergoing uniform circular motion is moving with a constant speed. Nonetheless, it is accelerating due to its change in direction. The direction of the acceleration is inwards.

Thus, the work done by the centripetal force in the case of uniform circular motion is 0 Joules. ... So if an object is moving in a horizontal circle at constant speed, the centripetal force does not do work and cannot alter the total mechanical energy of the object.

While the actual direction of the object (and thus, of the velocity vector) is changing, its direction is always tangent to the circle. To summarize, an object moving in uniform circular motion is moving around the perimeter of the circle with a constant speed.

Friction always works in the direction opposite to the direction in which the object is moving, or trying to move. Friction always slows a moving object down. The amount of friction depends on the materials from which the two surfaces are made.

Circular motion is the motion of an object which moves around a object in circular path. Rotatory motion is the rotation of an object on its own axis.

A change in velocity is known as an acceleration. The change in velocity due to circular motion is known as centripetal acceleration. Centripetal acceleration can be calculated by taking the linear velocity squared divided by the radius of the circle the object is traveling along.

The formula to calculate the coefficient of friction is μ = f÷N. The friction force, f, always acts in the opposite direction of the intended or actual motion, but only parallel to the surface.

Uniform circular motion can be described as the motion of an object in a circle at a constant speed. As an object moves in a circle, it is constantly changing its direction. At all instances, the object is moving tangent to the circle.

Thus, while the object moves in a circle at constant speed, it undergoes constant linear acceleration to keep it moving in a circle. However, it's angular velocity is constant since it continually sweeps out a constant arc length per unit time. Constant angular velocity in a circle is known as uniform circular motion.

['Centripetal acceleration ac is the acceleration experienced while in uniform circular motion. It always points toward the center of rotation. It is perpendicular to the linear velocity v and has the magnitude ac=v2r;ac=rω2 a c = v 2 r ; a c = r ω 2 .', 'The unit of centripetal acceleration is m/s2.']

The direction of velocity is perpendicular to the direction of the position and tangent to the circular orbit. Direction of velocity is constantly changing.

Friction is a general term. If you are referring to frictional force, then it's unit is Newtons (N). It's an opposing force and always acts opposite to the direction of motion. If you are talking about frictional coefficient (u), then it is dimensionless.
