Learning Outcomes:

You should be able to:

• state what is meant by scalar and vector quantities, and give common examples of each

• state what is meant by speed and velocity

• calculate average speed using total distance travelled/ time taken

• state what is meant by uniform acceleration and calculate the value of an acceleration using change in velocity/ time taken

• interpret given examples of non-uniform acceleration

• plot and interpret a displacement-time graph and a velocity-time graph

• deduce from the shape of a displacement-time graph when a body is: at rest, moving with uniform velocity and moving with non-uniform velocity

• deduce from the shape of a velocity-time graph when a body is: at rest, moving with uniform velocity, moving with uniform acceleration and moving with non-uniform acceleration

• calculate the gradient of a displacement – time graph and velocity – time graph to determine an object’s velocity and acceleration respectively.

• calculate the area under a velocity-time graph to determine the displacement travelled for motion with uniform velocity or uniform acceleration

• state that the acceleration of free fall for a body near to the Earth is constant and approximately 10 m/s²

• describe the motion of bodies with constant weight falling with or without air resistance, including reference to terminal velocity
