Motion — Core Learning Objectives
Note
- Define speed as distance travelled per unit time; recall and use the equation v = s / t
- Define velocity as speed in a given direction
- Recall and use the equation average speed = total distance travelled / total time taken
- Sketch, plot and interpret distance-time and speed-time graphs
- 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
- Calculate speed from the gradient of a straight-line section of a distance-time graph
- Calculate the area under a speed-time graph to determine the distance travelled for motion with constant speed or constant acceleration
- State that the acceleration of free fall g for an object near to the surface of the Earth is approximately constant and is approximately 9.8 m/s^2
