Question
Define force. What are its effects on objects?
✓
Answer
A force is a push or pull upon an object resulting from its interaction with another object. It has both magnitude and direction, making it a vector quantity. The unit of force is Newton (N), named after Isaac Newton.
Effects of force :
- Motion change: A stationary object may begin to move; a moving object may stop or change speed.
- Direction change: Force can alter the direction of a moving object.
- Shape change: Some forces deform objects, such as squashing or stretching them.
Examples:
- Kicking a football (starts motion)
- Applying brakes (stops motion)
