Key learning points
- The motion of faster objects is harder to stop.
- The motion of heavier objects is harder to stop.
- Objects with a greater mass need a greater force to start or stop it moving, and to change the direction of motion.
- A force is a push or a pull.
- A force is needed to change the motion or shape of an object.
Common misconception
A moving object has force that keeps it moving, and which runs out when it comes to rest.
Forces come from other objects. Forces change the motion of objects. Objects slow when forces act opposite to the direction of motion.
Keywords
Force - Forces are the pushes and pulls that objects exert on each other.
Exert - We say that objects exert forces on other objects.
Speed - The speed of an object is how fast it is going.
