JAMB Questions on Motion

Motion is defined as : The change in mass with respect to time The change in the position of a body with respect to time The change in volume with respect to time The change in energy with respect to time

• The change in mass with respect to time

• The change in the position of a body with respect to time

• The change in volume with respect to time

• The change in energy with respect to time

Which of the following quantities is a vector?

• Speed

• Distance

• Velocity

• Time

The slope of a displacement-time graph gives :

• Acceleration

• Velocity

• Displacement

• Time

If a body covers equal distances in equal intervals of time, the motion is:

A body starts from rest and accelerates uniformly at 5 m/s^2 for 4 seconds. What is its final velocity?

• 10 m/s

• 15 m/s

• 20 m/s
