Motion Graphs Flashcards
Equation to work out acceleration
A = v-u
——-
T
Acceleration = change in velocity over time
Equation to work out speed
Speed = distance / time
What is acceleration
The rate at which speed chanes
A straight line in a speed time graph means…
Constant acceleration
In speed time graphs and disnt time graphs on which axis do you put hinges
Time always goes along the bottom
In a distance time graph , what does the gradient represent
Speed
What is stopping distance
Thinking distance+ braking distance
What is braking distance
The amount if time it takes for the vehicle to stop moving once the brakes have been pressed
What is thinking distance
Also known as reaction time
The amount of time it takes a person to respond to a new situation
Stopping distance is inc by
Bad weather conditions eg ice Car is poorly maintained at is travelling faster Driver is drunk Driver is tired Tyres are in bad condition Mass of vehicle
