Friction is a contact force between systems that opposes the motion or attempted motion between them. Simple friction is proportional to the normal force N pushing the systems together. (A normal force is always perpendicular to the contact surface between systems.) Friction depends on both of the materials involved. WhatRead More →
A negative force is the force acting on an object against the applied force. The applied force here is positive that is aimed in the right direction whereas a negative force acts in the left direction. An example of negative force is deceleration, where the speed of a moving objectRead More →

If the forces that are acting on the body, are equal in magnitude and opposite in direction, the net force will be 0. This is the scenario of balanced forces. In such a case, the net force acting on the body is 0 and hence there is no change inRead More →
A force is a push or pull. Forces cause objects to change their motion. The only way a ball can get from one place to another is to be moved by a force. Objects are lazy. What is push force called? A push force or pull force is a forceRead More →
