In this topic I can:
P2a.1
Explain that velocity differs from speed because it has a
direction
P2a.2
Construct distance-time graphs and identify when an
object is stationary and moving at a steady speed.

P2a.4
P2a.5
P2a.6
P2a.7
Construct a velocity-time graph for objects moving with a
constant velocity and constant acceleration.
Explain that the slope of distance-time graph represents
the speed of an object
Calculate the velocity of an object given the distance
travelled and the time taken.
Explain how the slope of a velocity-time graph represents
the acceleration of an object
Calculate the acceleration of an object given its change in
velocity and the time taken for the change to happen.

P2a.8
Recall that the area under the line of a velocity-tie graph
represents the distance the object has moved.
123
P2a.9
Describe how forces are responsible for an object’s
change in velocity
123
P2a.10 Describe how forces can combine to produce a resultant
force and how it affects the object’s motion
123
P2a.11 Recall and use the equation:
force(N) = mass(kg) x acceleration(m/s2)
(F = ma)

Describe how some forces oppose motion and can be
used to slow/stop a moving object
P2a.13 Describe how various factors affect the time taken for a
vehicle to stop
P2a.14 Explain why a falling object reaches a terminal velocity

P2a.15 Higher use a distance –time graph to calculate the speed
of an object.

P2a.16 Higher Use a velocity-time graph to calculate (a) the
acceleration of an object, and (b) the distance it has
travelled.

In this topic I can:
P2a.17 Recall that when a force causes an object to move energy
is used and work is done

Describe how the work done is equal to the amount of
energy transferred

Recall that frictional forces transfer most energy into heat
P2a.21

both size and direction
P2a.24 Use the equation:
momentum = mass x velocity
(kg m/s)

P2a.25 Recall that a force acting on a moveable object changes
its momentum

P2a.26 Recall that momentum is not lost during a collision
between two bodies, provided there is no external force
acting
