Motion Checklist
• metre/second² (m/s²),
• Newton (N),
• second (s),
• Newton per kilogram (N/kg).
I can use the following units:
• kilogram (kg),
• metre (m),
• metre/second (m/s),
I can plot and interpret distance-time graphs
I know and can use the relationship between average speed, distance moved and time:
average speed 
distance moved
time taken
I can describe experiments to investigate the motion of everyday objects such as toy cars of tennis
balls
I know and can use the relationship between acceleration, velocity and time:
accelerati on 
change in velocity
time taken
a
v  u 
t
use the relationship between final speed, initial speed, acceleration and distance
moved:
(final speed)2 = (initial speed)2 + (2 × acceleration × distance moved)
v2 = u2 + (2 × a × s)
I can plot and interpret velocity-time graphs
I can determine acceleration from the gradient of a velocity-time graph
I can determine the distance travelled from the area between a velocity-time graph and the time
axis.
I can describe the effects of forces between bodies such as changes in speed, shape or direction
I can identify different types of force such as gravitational or electrostatic
I understand that friction is a force that opposes motion
I know and can use the relationship between unbalanced force, mass and acceleration:
force = mass × acceleration
F=m×a
I know and can use the relationship between weight, mass and g:
weight = mass × g
W=m×g
I can describe experiments to investigate the forces acting on falling objects, such as sycamore
seeds or parachutes
I can describe the forces acting on falling objects and explain why falling objects reach a terminal
velocity
I can describe the factors affecting vehicle stopping distance including speed, mass, road condition
and reaction time
