Force is a physical quantity that describes the interaction between two objects. It is a vector quantity, meaning it has both magnitude and direction.
Force can be applied in many ways, such as pushing, pulling, twisting, or lifting. It can also be applied using tools or machines, like a hammer or a lever.
Some common examples of force being applied include pushing a door open, pulling a wagon, lifting weights, and using a hammer to drive a nail.
Contact forces require direct physical contact between two objects, while non-contact forces act at a distance without physical contact. Examples of non-contact forces include gravity and magnetic forces.
Force is directly related to an object's motion. It can cause an object to speed up, slow down, change direction, or remain at rest. This relationship is described by Newton's second law of motion: F=ma, where F is force, m is mass, and a is acceleration.
