1 Forces and Motion – Part B “Motion”

Aims…

1.3 plot and interpret distance–time graphs

1.7 plot and interpret velocity–time graphs

1.8 determine acceleration from the gradient of a velocity–time graph

1.9 determine the distance travelled from the area between a velocity–time graph and the time axis.

1.4 know and use the relationship between average speed, distance moved and time:  average speed = distance moved/time taken

1.5 practical: investigate the motion of everyday objects such as toy cars or tennis balls.

1.6 know and use the relationship between acceleration, velocity and time:

acceleration = change in velocity/time taken     OR      a = (vu)/t

1.10 use the relationship between final speed, initial speed, acceleration and distance moved:

(final speed)2 = (initial speed)2 + (2 x acceleration x distance moved)     OR    v2=u2 + (2as)
