b) Movement and position
plot and interpret distance-time graphs
know and use the relationship:
average speed = distance moved / time taken
describe experiments to investigate the motion of everyday objects such as toy cars or tennis balls
know and use the relationship:
acceleration = change in velocity / time taken

determine the distance travelled from the area between a velocity-time graph and the time axis.
c) Forces, movement, shape and momentum
describe the effects of forces between bodies such as changes in speed, shape or direction
identify different types of force such as gravitational or electrostatic
distinguish between vector and scalar quantities
understand that force is a vector quantity
find the resultant force of forces that act along a line understand that friction is a force that opposes motion
know and use the relationship between unbalanced force, mass and acceleration:
force = mass × acceleration F = m × a
know and use the relationship:
weight=mass×g; W=m×g
describe the forces acting on falling objects and explain why falling objects reach a terminal velocity
describe experiments to investigate the forces acting on falling objects, such as sycamore seeds or parachutes
describe the factors affecting vehicle stopping distance including speed, mass, road condition and reaction time
know and use the relationship:
