Answers
Force is pull or push..
Friction force It is a force which tends to stop the relative motion between two bodies in contact.
Answer:
Frictional Force Definition: Frictional force refers to the force generated by two surfaces that contacts and slide against each other. ... If an object is pushed against the surface, then the frictional force will be increased and becomes more than the weight of the object.
Specific examples of sliding friction include:
Rubbing both hands together to create heat.
A sled sliding across snow or ice.
Skis sliding against snow.
A person sliding down a slide is an example of sliding friction.
A coaster sliding against a table.
A washing machine pushed along a floor.
A force is any interaction that, when unopposed, will change the motion of an object. A force can cause an object with mass to change its velocity (which includes to begin moving from a state of rest), i.e., to accelerate. Force can also be described intuitively as a push or a pull.

SI unit: newton (N)
Friction is a force that opposes motion on surfaces. Other examples of non-fundamental forces include the elastic force, tension, and frame-dependent forces, such as centrifugal force and the Coriolis force.
