Answer :
The direction of the force of sliding friction is always that of velocity of the object.
Moving against the surface's normal, the force of sliding friction acts in a direct proportion to the weight.
- Sliding or kinetic friction is the resistance to the actual relative sliding motion between two surfaces in contact.
- Let's start by learning about frictional forces from a basic understanding. If a metal block is on a table, it might not move in response to a weak force.
- The metal block begins to move as the force is gradually increased.
- The resistive force provided by the metal block in its static form is the same as the controlling value of the force at which the metal block begins to move.
- Static Friction is the name given to this resistive force. The metal block starts to budge as the experiment continues and the force is increased.
- Moving against the surface's normal, the force of sliding friction acts in a direct proportion to the weight. In particular, if the surface on which the body slides is horizontal, the normal force will be equal to the object's weight.
