1.2 MOTION DISTANCE-TIME GRAPH AND VELOCITY-TIME GRAPH CIE IGCSE PHYSICS

Learning Outcomes

Define speed and calculate average speed from total distance total time
Plot and interpret a speed-time graph or a distance-time graph.

Recognize from the shape of a speed -time graph when a body is
-at rest
-moving with constant speed
-moving with changing speed

Calculate the area under a speed-time graph to work out the distance traveled for motion with constant acceleration

Demonstrate understanding that acceleration and deceleration are related to changing speed including qualitative analysis of the gradient of a speed-time graph

Distinguish between speed and velocity

Define and calculate acceleration using change of velocity time taken
Calculate speed from the gradient of a distance-time graph
Calculate acceleration from the gradient of a speed-time graph

Recognize linear motion for which the acceleration is constant

Recognize motion for which the acceleration is not constant
Understand deceleration as a negative acceleration
