Explanation:
1 . Answer :A force can be a push or a pull. When a force is exerted on an object it can change the object's speed, direction of movement or shape. Pressure is a measure of how much force is acting upon an area. Pressure can be found using the equation pressure = force / area.
2. Answer :contact force = the force which are applied on body by making a physical contact is called contact force . Example of contact force is the force of friction. non contact force = the force experienced by a bodies even without being physical touched are called the non contact force. Example= gravitational force.
3 . Answer :contact force: applied force, Spring force, drag force, frictional force, normal force
Non-contact force: magnetic force, electric force, gravitational force.
