Forces and motion IGCSE paper 1

On a velocity time graph, a horizontal line represents

• acceleration

• constant speed

• deceleration

• stopped

At terminal velocity the forces up and down are

• unequal

• equal

• greater up

• greater down

on a velocity time graph, the area under the graph is

• acceleration

• deceleration

• distance covered

• time
