A body needs a force F1 just to start motion on a surface, a force F2 to continue its motion and a force F3 to roll on the surface. What is
Which of the following statements is incorrect? (a) static friction is greater than rolling friction (b) sliding friction is less than rolling friction (c) rolling friction is less than static friction (d) static friction is greater than sliding friction
The forces F1, F2, and F3 are acting on a particle of mass m, such that F2 and F3 are mutually perpendicular and under the effect of F1, F2, and F3 , the particle remains stationary. What will be the acceleration of the particle, if the force F1 is removed?
