What does this tell you about the effect of gravity on the velocity and acceleration of the marble as it rolled? Extra: Use ... Then graph your results, putting the average distance traveled ...

OK, let's do a simple experiment and use a graph to find a mathematical model. Constant Acceleration We are going to measure distance and time for an accelerating object and use that to find the ...

Velocity-time graphs show ... a decreasing rate to constant speed. Remember, acceleration is the same as gradient, and acceleration = velocity change ÷ time. To find the distance travelled ...

Key fact The gradient of speed-time and velocity-time graphs represent acceleration. The area under a speed-time graph represents the distance travelled ... travelling at a constant velocity ...
