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}}{\ ...

There's more to work than life.

Quantum computers promise to speed calculations dramatically in some key areas such as computational chemistry and high-speed networking. But they're so different from today's computers that ...

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-time graphs represent acceleration.
