Easy Summary Cambridge IGCSE Physics Coursebook for IGCSE/GCSE- Physics

Define these terms: 1. A car on a motorway travel 10 km in 6 Speed m/s = distance travelled (m)
minutes. A coach takes 7 minutes to Time taken (s)
travel the same distance. Which vehicle
1) Velocity was travelling faster? Explain your
Acceleration (m/s2) = change in velocity (m/s)
answer.
Time taken for change (s)
2) Gradient
Acceleration, a = V – U
3) Acceleration T
V = final velocity m/s
4) Deceleration U = Initial velocity m/s
T = time taken S



Explain the difference between speed and velocity:
What are the units for:
P1: Motion
Speed –
Acceleration –
Time – Distance time graphs
Distance –


1. The velocity of a car increased from 8 m/s
to 28 m/s in 8 s without change of
direction calculate:

a. its change of velocity –


Velocity time graphs
b. its acceleration –


2. When the car joined the motorway, its
velocity increased from 5 m/s to 25 m/s
in 10 seconds. What was its acceleration
during this time?



1. Calculate the average speed of a car travelling 1800 m in 60
seconds –

2. Calculate the speed of a car travelling 30 000 m in 1250
seconds –

3. A train travels at a constant speed of 35 m/s calculate how far
it travels in 20 s -
