PHYSICS – Speed, velocity and
acceleration AK
, LEARNING OBJECTIVES
1.2 Motion
Core Supplement
• Define speed and calculate average • Distinguish between speed and
speed from total time / total distance velocity
• Plot and interpret a speed-time graph • Define and calculate acceleration using
or a distance- time graph time taken change of velocity
• Recognise from the shape of a speed- • Calculate speed from the gradient of a
time graph when a body is distance-time graph
– at rest • Calculate acceleration from the
– moving with constant speed gradient of a speed-time graph
– moving with changing speed • Recognise linear motion for which the
• Calculate the area under a speed-time acceleration is constant
graph to work out the distance travelled • Recognise motion for which the
for motion with constant acceleration acceleration is not constant
• Demonstrate understanding that • Understand deceleration as a negative
acceleration and deceleration are acceleration
related to changing speed including • Describe qualitatively the motion of
qualitative analysis of the gradient of a bodies falling in a uniform gravitational
speed-time graph field with and without air resistance
• State that the acceleration of free fall (including reference to terminal velocity)
for a body near to the Earth is
constant
