Question

When a object is pushed with a force less than the frictional force. what happens to the object.pls kindly answer y questions

Answer 1

Well the concept is simple.

First and foremost there are three types of frictional forces.

1. Static friction
2. Limiting friction
3. Kinetic friction

Now the answer to your question will be based on these.

• When the body is at rest and you are applying force to move the body in a particular direction, static friction comes into play which is equal to the force that you are applying on the body ie.
• It is a self adjusting force and acts in a direction opposite to the direction in which you are applying the force.
• But there is a limit upto which this static force is self adjusting. The highest point of this limit is known as the limiting frictional force.
• The moment you apply a force greater than or equal to this limiting frictional force, the body will start moving in that paricular direction with constant accelaration(if you are applying a constant force).
• Now when the body is moving, it still experiences frictional force and this is known as kinetic friction which is constant.
• Thus if you stop applying the force to move the body, the body will come to rest because of this kinetic friction acting on the body.
