CAIE IGCSE Physics 1.2.12 A Deceleration Is a Negative Questions

Practise defining deceleration as negative acceleration and calculating its magnitude from changes in velocity and time in Cambridge IGCSE Physics problems.

Exam points

Define deceleration as negative acceleration or the rate at which velocity decreases, and calculate its magnitude from motion data.

[Maximum number: 2]

A ball of mass 130 g is launched from the ground at an initial velocity of $14 \mathrm{~m} / \mathrm{s}$ vertically upwards. It decelerates until it is at rest momentarily at a height h above the ground.

Define deceleration.

(deceleration is) decrease in velocity per unit time OR rate of decrease in velocity OR negative rate of change of velocity
$\mathbf{O R}-\Delta v / \Delta t$
negative acceleration OR change in velocity per unit time OR rate of change of velocity
