- motion p2.1
- vectors and scalars (p2.1.2)
- vector
- has magnitude and distance
- example: volcity and displacement

- scalar
- only has magnitude
- exaples: distance and speed

- vector
- acceleration (p2.1.3)
- the change in velocity is called acceleration
- the gradient of a volcity-time grpah shows the accleleration
- EQUATION: acceleration (m/s2) = change in velocity (m/s) / time (s)

- distance time graph (p2.1.4)
- straight line shows stationary
- diagonal line shows constant speed
- a curve shows acceleration/deceleration
- gradient give you speed
- EQUATION: average speed (m/s) = total distance (m) / time (s)

- velocity time graph (p2.1.5)
- straigh line shows constant velocity
- a steep line shows acceleration
- gradient gives you accerelation
- the area under the graph shows the displacement
- EQUATION: velocity (m/s) = displacement (m) / time (s)

- motion and kenetic energy (p2.1.6)
- EQUATION: kinetic energy (j) = mass (kg) * velocity2 (m/s) / 2
- SUVAT EQUATIONS
- v2 - u2 = 2as
- v = u + at
- s = ut + 1/2at2
- s = (u+v/2) * t

- S = displacement U = initial velocity V = finaly velocity A = acceleration T = time

- vectors and scalars (p2.1.2)
