plot and explain distance−time graphs

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

\(\text{average speed} = \dfrac{\text{distance moved}}{\text{time taken}}\)

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

know and use the relationship between acceleration, change in velocity and time taken:

\(\text{acceleration} = \dfrac{\text{change in velocity}}{\text{time taken}}\)

\(a = \dfrac{v-u}{t}\)

plot and explain velocity-time graphs

determine acceleration from the gradient of a velocity−time graph

determine the distance travelled from the area between a velocity−time graph and the time axis

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

(final speed)² = (initial speed)² + (2 × acceleration × distance moved)

\(v^2 = u^2 + (2×a×s)\)
