Distance, Speed And Acceleration Flashcards
How do you calculate acceleration?
Acceleration = change in velocity
Time
What does the slope on a velocity time graph tell us
The acceleration of the object
Is speed scaler or vector?
Scaler
Is velocity scaler or vector?
Vector
What’s the unit for acceleration ?
m/s 2
How do work out the overall stopping distance ?
Thinking distance + breaking distance
The greater the speed of the vihicle the greater the…..
Stopping distance
Why is using an air track useful while investigating motion?
It reduces friction
Why do we need speed cameras ?
Decrease the thinking distance, lowering risk of accident
Reduce kinetic energy of impact
Name 3 speed calming measures
Speed bumps
Awareness signs
Rumble strips
Define Inertia
The resistance of an object to change its state of motion. Mass and shape
What is Newton’s first law
An object at rest will stay at rest
