If the forces acting on a object are balanced...
it's at rest or has a constant speed.
it will speed up or slow down.
What is the correct equation?
Force = mass x acceleration
Mass = acceleration x force
Force = mass ÷ acceleration
Acceleration = force ÷ mass
Fill in the blanks: Force (__) = Mass (__) x Acceleration (__)
N, Kg, M/s^squared
N, G, M/s^squared
G, N, M/s
Stopping Distance = Thinking Distance + Breaking Distance
The thinking distance is the _________ travelled in this reaction time.
Distance
Speed
Time
The braking distance is the distance taken to stop once the brakes are applied.
How does the thinking distance increase?
It doubles when speed is doubled
Linearly.
If the speed doubles... the breaking distance is...
increased twice
increased four times
decreased twice
decreased four times
