What is the direction of friction forces?
opposing the motion
When a body slides over a surface the kinetic friction and static friction related as?
Kinetic friction is the friction that applies when an object is moving; static friction is the friction that applies when the object is not moving. Static friction must always be greater than, or equal to, kinetic friction.
What force is there on free falling body neglecting air friction?
The force of gravity is the primary acting force. Air resistance acts in the opposite direction.
When and object slides over a smooth horizontal surface how does the force of friction depend on the force of gravity on the object?
If the surface is smooth then it is almost frictionless. Hence the body will continue to move with constant velocity. However the object continues in a circular path and the weight is thus the centripetal force. It is assumed that the surface is very large)
Does an object always move in the direction of the unbalanced force exerted on it by another object?
Not always, the unbalanced force only points in the direction of the acceleration so a body may be moving in the opposite direction. Example. A car moves with some speed to the right on a horizontal surface and lock the brakes, if the surface has friction, but the net force acting on it is equal to the frictional force pointing left and produces a Deceleration of carriage until stop, but while this happens continuously in motion to the right.
What factor does the limiting value of the force of the static friction depend?
limiting friction is force of friction when a body slides over the surface of another body
What is the Direction of friction for a rolling body?
The direction of friction of a rolling body is in opposite direction to the motion of the rolling body.
Why does friction resist motion?
A friction is a force that acts in the opposite direction of a moving body. It acts at the meeting of two different surfaces. So friction always resists motion.
What is the Direction of Friction in Rotating Object in clockwise direction?
kinetic Frictional force always opposes the moving body... therefore its always is in the opposite direction
What is the direction of friction forces?
opposing the motion
Why is friction different from other forces?
Friction is the force exerted on a body when the body pushes against the microscopic obstacles in its path. Therefore , it is basically a reaction to the force exerted by the body.It comes into play when a body moves on a surface which is not completely even ,even at the microscopic level. Another difference is that the friction force is constant beyond a threshold for a given homogeneous surface,even if we increase speed of the body. Friction is essential for our movement and to keep in place things such as a knot. The resisting force employed usually by the resisting obstacles is the electromagnetic force.
How is friction a force?
Due to friction velocity of a body gets reduced, reduction in velocity causes change in velocity. This change in velocity leads to production of acceleration.(Because only acceleration can produce change in velocity either its direction or its magnitiude). And only a force can cause the acceleration hence friction is a force.

Is force necessary to change the speed or direction of a body?
Yes, force is necessary to change any motion of an object. The force can, for example be gravity or friction. Without these two factors, an object would continue moving in its original velocity (speed and direction) in eternity.
When a force is applied to a body in what direction will the body accelerate?
Acceleration is in the same direction as the applied force.
What is the relative resistance to movement of one body as it slides over another is repersented by what?
the coefficient of friction
What is the name of the force that always acts against the direction of movement?
In geneal frictional force. If it rubs against a surface then it is known to be friction. If it drags the moving body then it is said to be viscous drag.
