Chapter 2 : Kinematics of Linear Motion (C1&C2)

Changes in our speed, direction or both are called _________.

• distance

• velocity

• acceleration

• displacement

If a student rides her skateboard on a straight road and does not speed up or slow down, she is travelling with a

• uniform acceleration

• positive acceleration

• uniform velocity

• negative velocity

Which of the following best define instantaneous velocity?

• the rate of change of displacement

• average displacement at any time

• changes of velocity at constant rate

• velocity at a particular time

Alya moves with ___________________ when the magnitude and direction of the acceleration remain unchanged.

• uniform velocity

• average velocity

• uniform acceleration

• average acceleration

A car on the roads moves with the following speed at each instant of time:

0 s : 0 ms^-1

2 s : 10 ms^-1

4 s : 20 ms^-1

6 s : 30 ms^-1

Which of the following best describe the motion?

• constant acceleration, increasing velocity at constant rate

• deceleration, decreasing velocity

• zero acceleration, constant velocity

• acceleration, increasing velocity
