Слайд 2What’s the Connection?
Speed – is distance (metres) / time (seconds)
and is measured in metres per second
Слайд 3What’s This?
What do distance-time graphs show?
A graphical representation of a
journey showing how long it took and how far it
was. The speed can also be calculated using the gradient of the lines.
Слайд 4What’s the Connection?
Momentum – is calculated by mass (kg) x
velocity (m/s) and has the units kg m/s

Слайд 5What’s the Connection?
Crumple zone – the area in a vehicle
which, in the event of a crash, is designed to
buckle at the front and or the back to reduce the impact of the force on the passengerscrash

Слайд 6What’s the Connection?
Factors that affect reaction times – all of
these can distract a driver and reduce their reaction time
therefore not stopping the car as quickly as might be necessarytiredness

Слайд 7Why?
Stopping distance is the distance a vehicle travels in order
to stop. It is calculated by adding the thinking distance
to the braking distance.If I am travelling in a car and apply the brakes, why does the car still travel after I have seen the danger?
The thinking distance is the distance travelled by the vehicle once the hazard has been spotted and the driver reacts. The braking distance is the distance travelled by the vehicle once the driver has applied the brakes.
What are these?
Слайд 8What’s Being Described?
Newton’s first law – balanced forces
An object travelling
at a constant speed, or remaining stationary has all the
forces balanced and the resultant force is zero.Terminal velocity
I am a skydiver and have reached a point where my weight is balanced by resistive forces – how fast am I travelling?
