Force is a push or pull acting on an object, and it may change the object's speed, direction of motion, state of rest, or shape.
Practice This ConceptMain explanation
Teacher explanation
A force is understood from its effect. If a stationary ball starts moving, a moving ball slows down, or a spring changes shape, a force has acted. Force is a vector quantity, so direction matters along with magnitude.
Example
When a footballer kicks a stationary football, the kick applies force and the ball starts moving in the direction of the kick.
Simple analogy
Force means push or pull, but exam answers need the effect also.
Common confusion
Students often write that force is needed only to start motion, but force can also stop, slow down, speed up, change direction, or change shape.
Exam tip
While answering, mention both the type of effect and the object on which force acts.
