Pressure and force

What is pressure? Pressure is the amount of force appliecd perpendicular to the surface of an object. To find area, the formula( Force(N)/Area(m2)). If the area increases, the pressure decreases and vise versa. If the force increases, the pressure increases, and vise versa.

So, now, what is force? Force is a push or a pull. Although force cannot be seen, but you know that a force is acting on it as there is an effect on the object. A force can move a stationary object, stop a moving object, change the direction of an object, accelerate a moving object and change the shape of an object. Example of a force is gravity, friction, magnetic force and elastic force. Gravity is the force that pulls us down back on earth. If there was no gravity,we would not be on the ground. Friction is the force that opposes motion. It goes in the other direction as the moving object. If there was no friction, the object would not stop moving. To reduce friction, lubricant can be applied on the surface.Elastic force is the force when an elastic object is streched. The force would force the spring, or elastic object, back to its original shape. Finally, magnetic force is the force of attraction or repulsion between two magnetic objects. Thus, magnetic force can either be a push or a pull. Also, magnetic force can act at a distance.
