need to design a worksheet just from this!

2. Kinematics

Content

• Speed, velocity and acceleration

• Graphical analysis of motion

• Free-fall

• Effect of air resistance

Learning Outcomes:

Candidates should be able to:

(a) state what is meant by speed and velocity

(b) calculate average speed using distance travelled / time taken

(c) state what is meant by uniform acceleration and calculate the value of an acceleration using

change in velocity / time taken

(d) interpret given examples of non-uniform acceleration

(e) plot and interpret a distance-time graph and a speed-time graph

(f)

deduce from the shape of a distance-time graph when a body is:

(i)

at rest

(ii)

moving with uniform speed

(iii)

moving with non-uniform speed

(g) deduce from the shape of a speed-time graph when a body is:

(i)

at rest

(ii)

moving with uniform speed

(iii)

moving with uniform acceleration

(iv)

moving with non-uniform acceleration

(h) calculate the area under a speed-time graph to determine the distance travelled for motion with

uniform speed or uniform acceleration

(i)

state that the acceleration of free fall for a body near to the Earth is constant and is

approximately 10 m/s

2

(j)

describe the motion of bodies with constant weight falling with or without air resistance,

including reference to terminal velocity
