2.01 - Speed, Velocity & Acceleration

Average Speed = Total Distance / Total Time Velocity - Speed + Direction [Vector Quantity] - Displacement / Time Acceleration - Rate of change of velocity - Change In Velocity / Time

2.02 & 2.05 - Motion Graphs

GRADIENT - Speed

0.5vt^2 = distance when acceleration and initial speed is given

GRADIENT - Acceleration AREA UNDER - Distance Travelled

2.03 - Recording Motion

2.04 - Free Fall

Acceleration Due To Gravity = 9.8 m/s^2

Further away from earth = Less g

2.06 - Forces In Balance

Force - Push or pull, exerted by one object onto another. [Has a direction and magnitude] - MAY PRODUCE CHANGES IN SIZE AND SHAPE of an object
