Force
- Force is an external agent that can change a body's state of rest or motion.
- It has two main characteristics: magnitude and direction.
- The direction of the force is the direction towards which it is applied.
- The point where the force is applied is known as the application of force.
Measuring Force
- Force can be measured using a spring balance.
- The SI unit of force is the Newton (N).
