But if you calculate the acceleration without the graph, you are explicitly stating ... The only thing that changes is the direction of the frictional force. I will call this a x2.

Damage from acceleration depends on the magnitude of the acceleration, the direction, the duration ... Acceleration is just a change in velocity over time, and if you're talking about simple ...

The amount of the force and the location where it is providing the push can change either or both the speed (the magnitude part of acceleration) and direction. Now that we know how a massive body ...

gradient = \(\frac{change~in~y ... Velocity-time graphs show velocity on the vertical axis. Acceleration is still represented by the gradient. Key fact The gradient of speed-time and velocity ...

Speed-time graphs show speed on the vertical axis and time on the horizontal axis. The gradient of a speed-time graph represents acceleration because: gradient = \( \frac {\text{change in y} ...
