What is the formula for speed?
Average speed= distance/time
1 of 11
What does the gradient of a distance-time graph show?
The speed of the object, a higher speed means a steeper gradient
2 of 11
What does a straight line on a distance-time graph indicate?
That the speed is constant
3 of 11
What does a curved line on a distance time-graph show?
That the speed is changing
4 of 11
What is the area under a speed-time graph equal to?
The distance travelled
5 of 11
What is the formula for measuring acceleration?
acceleration=change in seed(velocity)/ time taken
6 of 11
What is acceleration measured in?
Metres per second squared (m/s squared)
7 of 11
What is velocity? Why?
A vector, it has both size (speed) and direction
8 of 11
When two cars are moving past each other, what is their relative velocity? (Two things)
1- The sum of their individual velocities if they are going in opposite directions. 2--The difference of their individual velocities if they are going in the same direction.
9 of 11
Even if a vehicle goes around a roundabout at a constant speed it is still accelerating, why?
Its direction of travel is changing, it's not going in a straight line
10 of 11
Any object moving along a circular path moves at a...?
Tangent to the circle, or arc of a circle
