1.1 Reminders from Forces & motion section 1. on distance-time graphs

Distance - time graphs

Graph shows acceleration, object speeding up, ∆d/∆t gradient increasing.

Graph object shows zero speed/velocity, ∆d/∆t is constant at zero, object is stationary.

Graph deceleration, object is slowing down, ∆d/∆t is decreasing.

Graph shows uniform or constant speed/velocity, not acceleration, ∆d/∆t is constant, but not zero.

DO NOT confuse these graphs with the velocity-time graphs below!

Keywords, phrases and learning objectives for distance-time graphs for a moving object

Be able to interpret distance-time graphs in terms of constant speed, changing speed - acceleration and deceleration and object stationary.
