1. Newton`s I law (a) state each of Newton’s laws of motion
(b) show an understanding that mass is the property of a body that resists change in motion
(c) describe and use the concept of weight as the effect of a gravitational field on a mass

2. To do Read p44&45 Write Newton`s 1st law in your notes
In your notes explain
Why you would tend to fall over if you jumped from a moving vehicle
Why a moon rock may feel about the same weight as a football but should never be kicked
The difference between inertial mass and gravitational mass

3. (d) define linear momentum as the product of mass and velocity
(e) define force as rate of change of momentum
(f) recall and solve problems using the relationship F = ma, appreciating
that acceleration and force are always in the same direction
Newton’s II law

4. Need to know Students should be familiar with the law expressed as:
F =ma
F = Δp/Δt

5. To do Carry out the experiment Read p46-47
Answer questions on worksheet
P58 q 2-5

6. Newtons III Law State Newton’s third law of motion.
Discuss examples of Newton’s third law.
Newtons III Law

7. Need to know
Students should understand that when two bodies A and B interact, the force that A exerts on B is equal and opposite to the force that B exerts on A.

8. ‘Conservation of Force’
If body A exerts a force on body B then body B will exert the same force on body A but the force will be in the opposite direction.’

9. The book on the table
