Question 21
The table below shows the mass and velocity of four objects. Which object has the least inertia?
objects mass velocity (m/s)
W 16 2
X 15 3
Y 13 20
Z 2 30


a.) Y
b.) W
c.) Z
d.) X

Answer 1

Inertia is the property of an object that quantifies its resistance to changes in its motion. It is directly proportional to mass; hence, the greater the mass of an object, the greater its inertia.

To find which object has the least inertia, we need to look at the mass of each object since velocity does not affect inertia directly.

Here are the masses of the objects:
- Object W: 16 kg
- Object X: 15 kg
- Object Y: 13 kg
- Object Z: 2 kg

Among these, object Z has the least mass (2 kg), and therefore, the least inertia.

The answer is:
**c.) Z**
