Chapter 3 Flashcards
What is distance?
The length of the path travelled between 2 points
What is speed?
Distance travelled per unit time. It is the magnitude of the velocity vector
What is acceleration?
Rate of change of velocity
What is displacement
Length of the shortest path between 2 points according to direction
What is velocity?
Rate of change of displacement
What is uniform acceleration?
When speed changes at a constant rate
Suvat equation without displacement
V=u+at
Suvat equation without final velocity
S=ut+0.5at^2
What is the Suvat equation without a?
S=0.5(u+v)*t
Equation without t
V^2=U^2+2as
What is the thinking distance?
Distance car travels whilst driver is reacting
What is braking distance?
Distance car travels whilst driver applies the breaks
What is stopping distance?
Thinking distance+Braking distance
How to calculate thinking distance and breaking distance?
Thinking distance=speed*reaction time
Braking distance-Suvat equations
Factors which affect driver
Tiredness
Alcohol
Drugs
Distraction
