What is the formula for speed
Distance / time
What does a constant gradient on a distance-time graph tell us
Constant speed
What does a upward curl on a distance time graph tell us
Accelarating
what does a straight line on a distance/time graph tell us
stationary
what does the gradient tell us on a distance-time graph
tells us the speed
what is the equation for acceleration that uses time
change in velocity/time
what is the formula for an equation that uses distance
V squared - u squared = 2 * acceleration * distance
what does a flat line on a velocity-time graph tell you
constant speed
what does an increasing slope on a velocity-time graph tell you
acceleration
how do you find the distance from a velocity-time graph
the area under the line
