On the graph of velocity vs. time, Δv/Δt is the slope of the curve. If the curve is straight, the acceleration is constant. If the curve isn't straight we have to do the same trick we did before with ...

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.

Instantaneous Velocity. Instantaneous velocity is defined as the limit of the average velocity as the time interval Δt becomes infinitesimally small. Its dimensions are [M 0 L 1 T-1] and its S.I ...

Position- time graph. Speed and velocity: ... Escape velocity, motion of a satellite, orbital velocity, time period and energy of satellite. UNIT 7: PROPERTIES OF SOLIDS AND LIQUIDS.

A negative gradient shows the rate of “slowing down” or deceleration. Velocity-time graphs show velocity on the vertical axis. Acceleration is still represented by the gradient. Key fact The ...
