Sir,
I have a query?
Can you tell me which is the direction of static friction acting on us when we do run over a treadmill when
a) we are at rest with respect to ground
b) we are accelerating with respect to ground either in forward or in backward direction of our run.
Dear siddharth,
Static friction is the friction experienced when we try to move a stationary body on a surface, without actually causing any relative motion between the body and the surface which it is on.
It can be defined as the force of friction which exactly balances the applied force during the stationary state of the body.
Static frictional force is a self-adjusting force. i.e., the static friction will always be equal and opposite to the force applied.
Consider the figure, R is the reaction force due to the weight W. fr is the friction and F the external force. F = -fr when no motion occurs.
