Which axis is distance and time on on a graph?
Distance:y Time:x
what does the gradient of the line of a distance time graph tell us?
The speed
What does horizontal line on a distance time graph represent?
The object is stationary
Change in velocity formula
Change in velocity= final velocity - initial velocity
Acceleration formula
Acceleration= change in velocity (final velocity-initial velocity) / time taken
What does A, B, C, D represent?
A: deceleration, B: acceleration, C: constant velocity, D: stationary
Formula linking final speed, initial speed, acceleration, displacement
Final speed= initial speed + 2 x acceleration x displacement
How to find the distance travelled in a velocity time graph
Use the area
What is stopping distance?
Thinking distance + braking distance
What is thinking distance and examples of affecting factors
Distance covered while reacting. Eg. age, mental impairment, focus, alcohol, drugs, tiredness
Braking distance meaning and examples of affecting factors
Distance covered while braking. Eg. friction, road surface, mass of vehicle, speed of vehicle, brake/tyre condition
