What objectives does this worksheet meet?
Core
- I can define speed as the distance travelled per unit time, and I can recall and use the equation v = s/t.
- I can define velocity as speed in a given direction.
- I can recall and use the equation average speed = total distance travelled / total time taken.
- I can sketch, plot and interpret distance–time graphs and speed–time graphs.
- I can decide, qualitatively, from given data or from the shape of a distance–time graph or a speed–time graph, whether an object is:(a)at rest(b)moving with constant speed(c)accelerating(d)decelerating
- I can calculate speed from the gradient of a straight-line part of a distance–time graph.
- I can work out the distance travelled by calculating the area under a speed–time graph, for motion at constant speed or with constant acceleration.
- I can state that, near the surface of the Earth, the acceleration of free fall g of an object is approximately constant, at approximately 9.8 m/s².
Extended
- I can define acceleration as the change in velocity per unit time, and I can recall and use the equation a = Δv/Δt.
- I know that a deceleration is a negative acceleration, and I can use this in calculations.
- I can describe the motion of objects falling in a uniform gravitational field, both with and without air or liquid resistance, including terminal velocity.
