What two quantities are needed to calculate speed?
Speed = d ÷ t (distance ÷ time)
1 of 5
What does the gradient of a distance- time graph represent?
The slope represents the increasing speed of an object.
2 of 5
State the equation used to calculate acceleration
a = (V-U) ÷ T (Final speed - Initial speed ÷ time)
3 of 5
What is acceleration and deceleration?
It is a measure of how quickly an object speeds up or slows down.
4 of 5
What does an acceleration of -5m/s² tell you about the motion of the object?
This tells you that the object is going in reverse direction, it is decelerating and going back to it's starting point.
