Study Notes
Force in Physics
- Force is a push or pull that causes an object to change its motion or shape.
- Force is required to give motion to an object, meaning it is necessary to apply a force to make an object move.
- Force is the cause of the motion of an object, exemplified by the motion of a car, which is caused by the force generated by its engine.
- Force is also needed to stop the motion of an object, implying that a force must be applied in the opposite direction to bring the object to rest.
- There are different types of force, which will be explored in more detail.
