Think back to GCSE 1.Write down the definition of velocity Speed in a given direction 2.Write down the calculation for velocity But that is how you calculate speed, which you just said is different to velocity

3
Thursday, 14 November 2013 1.1.2 Scalars and Vectors Learning Objectives: Understand the difference between scalars and vectors. Add and subtract vectors. Work out the x and y components of a vector.

6
Distance (x) Displacement (s)

7
Velocity (v) = Displacement (s) Time (t) Speed (v) = Distance (x) Time (t) Scalar Vector Magnitude Direction Magnitude

8
Vectors Some quantities need to have a direction to be meaningful. Force for instance can be big or small but we need to know the direction it acts if it is to be useful. Vectors are quantities that have BOTH a Magnitude and a Direction We can represent them with ARROWS 10 N Right10 N Left or -10N

9
Velocity Acceleration Momentum Force Displacement Electric field strength Time Distance Speed Temperature Mass Power Energy Vectors Scalars

10
Vector Addition Is not like ordinary arithmetic You have to take account of the direction Two ways to do it – Scale drawing – Trigonometry

11
H O A

12
FyFy FxFx F = Fcos = Fsin
