• Velocity

• Acceleration

• Speed

• Mass

Momentum is calculated by multiplying an object’s mass by its --------------

• Mass

• Velocity

• Work

• Inertia

What is the unit of the acceleration ?

• m

• m/s

• (m/s) /s

• kg m/s

Which describes how objects to resist changes in motion?

• Distance

• Speed

• Accelration

• Inertia

The acceleration of a car starts from the rest and reach a velocity of 3 m/s in 3 seconds is ..........

• 1 (m/s) /s

• 3 (m/s) /s

• 6 (m/s) /s

• 9 (m/s) /s

What is the acceleration of a car moving with velocity of 150 m/s after 5 seconds in the north direction

• 750 (m/s) /s north

• 30 (m/s) /s north

• 30 (m/s) /s south

• 75 (m/s) /s north

The momentum for object has a mass is 4 kg and its velocity 5 m/s is

• 9 kg m/s

• 5 kg m/s

• 20 kg m/s

• 1 kg m/s

Speed = Distance x Time

• True

• False

Speed = Distance / Time

• True

• False

Acceleration is the change in speed divided by the time

• False

• True
