The speed-time graph below illustrates how the speed of an object changes with time. A horizontal line on a speed-time graph represents a steady speed. This can also be called a constant or uniform ...

This force will cause the cart to accelerate—in this case, to the left, or the opposite way it was heading, which is why it slows down during impact and even reverses direction. But what is the ...

The gradient of a displacement-time graph at a particular time gives the velocity of the object at that time. The gradient of a velocity-time graph at a particular time gives the acceleration of the ...
