1 The Affect of Forces on Motion 5-5.1

2 A push or a pull

3 FORCE

4 What forces can affect motion?

5 Magnetism Gravity Friction

6 What are the four ways that force can affect motion?

7 Slow things down, Speed things up, Stop things Change their direction

8 A force that acts at a distance and cannot be seen. It comes from the furthest regions of the Earth.

9 Magnetism

10 Materials that have magnetic force

11 MAGNETS

12 Poles that are the same – S to S and N to N...

13 REPEL

14 Opposite poles – S to N and N to S will...

15 ATTRACT

16 What happens to magnetic forces when they get closer?

17 THE GET STRONGER

18 Where is the greatest strength of magnetic forces on a magnet?

19 AT THE POLES

20 A pull that attracts one object to another

21 GRAVITY

22 When do you notice this attraction of one object to another?

23 WHEN THE OBJECT IS BIG like a pencil to the Earth

24 What does the attraction of the Moon cause on the Earth?

25 TIDES

26 How does the Sun’s gravity affect the Earth?

27 KEEPS IT REVOLVING

28 The force that opposes motion when surfaces are touching

29 FRICTION

30 How can you make more friction?

31 MORE MASS Rougher Surfaces

32 How can you reduce the affect of friction?

33 LUBRICATION or ROLLERS

34 In which states of matter does friction occur?

35 SOLIDS LIQUIDS and GASES
