Practicing Success
A block of wood is placed on a surface. A force is applied parallel to the surface to move the body. The frictional force developed acts : |
normal to the surface downwards normal to the surface upwards opposite to the direction of the applied force along the direction of the applied force |
opposite to the direction of the applied force |
Friction force always oppose the applied force. Hence, frictional force acts opposite to the direction of he applied force. |
