Speed And Acceleration Flashcards
(9 cards)
What is speed?
Speed in a measure of how quickly an object can move from one place to another
How do you calculate speed , distance , time
Distance = speed x time
Time = distance divided by speed
Speed = distance divided by time
(Dads Silly Triangle)
Travelling at the same speed ….
Constant
Speeding up…
Accelerating
Slowing down…
Decelerating
What is displacement ?
Displacement is distance with a given direction
What is is acceleration?
The acceleration of an object is the change in velocity in one second
Acceleration = change in velocity divided by time taken
What does the slope in distance graph tell us
The slope in a distance vs time graph tells you the SPEED
What dose the slope of a velocity-time graph tell us ?
The slope of a velocity-time graph tells us the ACCELERATION of a body
