Question
How do you measure the inertia of an object?
- By its direction
- By its speed
- By its height
- By its mass
Hint:
- Inertia is a property of matter by which it remains at the state of rest or in uniform motion in the same straight line unless acted upon by some external force.
- Inertial is the effect of mass.
The correct answer is: By its mass
- Mass is a quantitative measure of a body’s inertia.
- Mass is the amount of matter present in a body.
- inertia is proportional to mass. If mass increases, then inertial will increase.
- If we have an idea about the mass of a body, then inertia can be measured.
