17. What units do we use for forces?
The Newton (N)
1. When and where did Newton live?
2. What are Newton’s 3 laws of motion?
NEWTON

18. Force Meter or Newton Meter
Measures how large a force is
Three laws come onto later
Theory of gravity
Units for forces was named after him

19. Measuring forces Measurement Force (N) Lift pencil case

Lift your school bag
Lift your water bottle

20. Forces

21. Balanced forces

23. Showing forces
We cannot see forces, but we can see the effects of the force. We show the direction of the force as arrows.

24. Representing Forces
The direction of the arrow shows the direction of the force The length of the arrow shows the size of the force

25. If the table suddenly vanished, the book would fall to the floor.
The force pulling the book down is greater than the force pushing it up.
This is known as an unbalanced force.
2: One force is larger than the other so the book moves
3: Forces act in pairs

26. Complete Unbalanced forces sheet

27. GRAVITY REACTION FORCE
The car is not moving. The same forces are acting on it that were acting on the book.
GRAVITY
REACTION FORCE

28. What would happen if the car started to move forwards really fast?
GRAVITY
AIR RESISTANCE
THRUST
REACTION FORCE

29. MISCONCEPTION ALERT!
If a car is travelling at a CONSTANT SPEED – the forces are balanced so arrows should be the same size.

30. MISCONCEPTION ALERT!
If a car is SPEEDING UP – the forces are unbalanced so the arrows are different sizes.

31. MISCONCEPTION ALERT!
If a car is SLOWING DOWN – the forces are unbalanced so the arrows are different sizes.

32. CONSTANT SPEED AGAIN = forces are balanced
MISCONCEPTION ALERT!
CONSTANT SPEED AGAIN = forces are balanced

33. Add in arrows onto your diagrams

34. Forces Videos In your groups on your tables – create a video to show:
2 unbalanced forces
2 balanced forces
On any object in the room you can find!
You can cut out arrows to help you.
Here are some key words to help you
Balanced
Unbalanced
Speeding up
Constant speed
Slowing down
You have today, and the double on Tuesday to do this.
Class will view them on Wednesday and then go through tests
Videos should be approx 3 mins
Level ladders will be on your tables to help you include all the information you need to reach your targets

36. Dropping heavy objects simultaneously Parachutes Friction Pushing boxes forces acting Spring balance weighing Newtons Law Magnets Magnetic shield Magnetic materials Compasses working around the earth Cars and heights of ramps Imporatnce of repeats

37. Types of forces Gravitational Friction Tension Normal Air resistance
Applied
Spring
Magnetic
Force applied to an object by a person or object
An object attracts another objects towards itself
Attraction or repulsion that arises between electrically charged particles because of their motion
Supporting force of a stable object that is in contact with something
Exerted by a surface as an object moves across it
Acts on objects moving through the air
Force transmitted through a string, rope, cable or wire when pulled tight by forces acting from opposite ends
Exerted by a compressed or stretched spring on any object attached to it

38. Contact or Non-contact?
Indicate on your forces if you think they are contact or non-contact forces?
Three laws come onto later
Theory of gravity
