the meaning of networkingWebForce of friction. The force which resists the relative motion of a surface is called as Friction. The force of friction is offered by all types of surface such as solid, liquid and the air. The force of friction is always applied in the opposite direction of the movement. When the two substance move towards each other, then friction is applied. tiffany road angelWebSep 18, 2024 · Force and Laws of Motion Class 9 Numericals are solved in the following sections. Solution of Problem 1 A force will cause an acceleration a. a = force/mass = 10/1 m/s^2 = 10 m/s^2 The force acts for 0.1 seconds.
