Force is defined as the push or pull experienced by the object because of another object. To apply force, minimum two objects need to be involved: one which exerts force and the other that experiences the force. For example, sliding a book over the surface of the table. It is interesting to know that force can either act in the same direction or in opposite directions. When a force acts in the same direction, the net force is the sum of the magnitude of both the force. Whereas when a force acts in the opposite direction, the net force is the difference between the magnitude of both the forces. Following are the effects of force:
Force can change the state of motion
Force can change the shape and size of an object
Force can change the direction of the moving object
There are two types of forces: contact force and non-contact force. Frictional force and muscular forces are the types of contact force while a magnetic force, the gravitational force, and the electrostatic force are the types of non-contact force.
The pressure is defined as the force acting per unit area of a surface. Liquids and gases are capable enough of exerting pressure on the inner walls of the container in which they are kept. The pressure exerted by the air is known as atmospheric pressure. Following is the formula of pressure:
