CONCEPTS
The difference between mass and weight
The effect of a force. ( a force is a push, pull or twist) It can alter how a body moves (direction/velocity) or its shape
Types of force: gravity force, contact force, friction force, magnetic, electrostatic, muscular, centripetal.
How they act and the direction of action (see syllabus)
Gravity force varies in space and on the Earth
Force is measure in Newtons. (1kg weighs 10N (approx))
Inertia
The coefficient of friction
LESSONS
Extension of a spring changing with weight of mass extending it (Hooke's Law)
Methods of measuring forces
Inertia experiments
