First 140 words of the document:

Physics

Velocity and distance time graphs

Speed how fast you're going

Velocity direction and speed in which travelling

Distance time graphs (pg. 72)

X axis time y axis distance gradient speed

Flat sections represent stopping

Calculating speed is the gradient vertical distance

Time

Acceleration is how fast the velocity is changing. Rate of change in speed

Formula for acceleration is: change in velocity

Time taken

E.g. Calculating the speed of the start journey. The vertical distance on this graph is 8m and the time taken is 4

secs so its 8/4 = 2m/s

Velocity time graphs

Y axis - velocity X axis time gradient acceleration (m/ s2 )

Flat sections represent steady speed

Calculate acceleration is the gradient vertical change

Horizontal change
