Dear student,
When friction supplies the force that accelerates the object.
Tires on an accelerating car (Friction between tires and road)
Box dropping onto a moving belt (Friction between box and belt)
A runner at the start of a race (Friction between shoes and ground)
Swimmer at start of race (Feet to edge of pool)
Please feel free to ask your queries here. We are all IITians and here to help you in your IIT JEE preparation.
All the best.

when a body is rolling with some angular velocity & no linear velocity on a frictious surface then friction force acts in foreward direction & supports the linear motion...
here friction acts as driving force & thus Kinetic energy is increased....

Three identical balls are placed on a frictionless
horizontal surface touching each other. They stick to
each other because of adhesive. Another ball of same
radius and mass m is placed over the void created by
the three balls. Find the forces applied by the balls
kept on the floor to each other if the system remains
in equilibrium.
