A force can be defined as any push or pull which changes or tends to change the state of rest or state motion of a body. Force is a vector quantity having both magnitude and direction. The SI unit of force is newton and is denoted by N .

Weight of a body is defined as the force exerted on a body by gravity. Like all forces, weight also has a direction and it points vertically downward. Weight of a body can be given by, W = m g Where m is mass and g is acceleration due to gravity

Friction is a contact force which appears when two bodies are in contact with each other. Friction opposes the relative motion between two bodies and acts in a direction opposite to that of the applied force. Friction is necessary for the stability of the body.
