Calculate the distance in
meters using the speed triangle
1)
A bird travels at 65m/s for 90s
2)
A plane travels at 400m/s for 2000s
3)
Superman travels at 2km/s for 120s
4)
A passenger aircraft travels at 250m/s for 2 hrs
5)
A snail travels at 1.5cm/s for 30 min
Don’t forget to
convert
Them all to
m/s!!!
Baseline (Aiming for 4):
Describe the
difference between distance and velocity and calculate
velocity.
Further (Aiming for 6):
Rearrange the
acceleration equation and calculate the velocity for an
object under constant acceleration.
Challenge (Aiming for 8):
Combine
equations relating to velocity and acceleration in multistep calculations
Now try this one…

A car is travelling with a starting velocity of 90m/s and then after 10s its
velocity changes to a final velocity of 50m/s.
1)
Calculate the acceleration of the car.
2)
Describe what is happening to the car.
