Question 35

Question

The table below shows the mass and velocity of four objects. Which object has the least inertia?
Table:
Object Mass(kg) Velocity(m/s)
W 16 2
X 15 3
Y 13 20
Z 2 30

a:Z
b:W
c:X
d:Y

Answer 1

Inertia is a property of matter that is proportional to mass. Therefore, to determine which object has the least inertia, we simply need to look at their masses, since all objects will have the same inertia regardless of their velocities.

Here are the masses of the objects:

• Object W: 16 kg
• Object X: 15 kg
• Object Y: 13 kg
• Object Z: 2 kg

The object with the least mass (and thus the least inertia) is object Z, which has a mass of 2 kg.

The answer is: a: Z
