Outcomes
- Student should be able to give examples for, label and name a range of forces.
- Students should know that forces might: 1) change the speed of a moving object 2) change the direction of a moving object 3) change the shape of an object
- Students should know how to add simple forces along a straight line and understand when force are balanced the object will remain stationary (they are not required to know that the object may also be travelling at constant speed if the forces are balanced)
