1.2 Motion
| Core | Supplement |
|---|---|
1 Define speed as distance travelled per unit time; recall and use the equation 2 Define velocity as speed in a given direction 3 Recall and use the equation |
4 Sketch, plot and interpret distance–time and speed–time graphs
5 Determine, qualitatively, from given data or the shape of a distance–time graph or speed–time graph when an object is:
(a) at rest
(b) moving with constant speed
(c) accelerating
(d) decelerating
6 Calculate speed from the gradient of a straight-line section of a distance–time graph
7 Calculate the area under a speed–time graph to determine the distance travelled for motion with constant speed or constant acceleration
8 State that the acceleration of free fall g for an object near to the surface of the Earth is approximately constant and is approximately
9 Define acceleration as change in velocity per unit time; recall and use the equation 10 Determine from given data or the shape of a speed–time graph when an object is moving with: (a) constant acceleration (b) changing acceleration 11 Calculate acceleration from the gradient of a speed–time graph 12 Know that a deceleration is a negative acceleration and use this in calculations 13 Describe the motion of objects falling in a uniform gravitational field with and without air/liquid resistance, including reference to terminal velocity |
