Question

introduction to physical science (physics) quiz
the measure of the bodys resistance to acceleration by some external force is its ______
a weight
b inertial mass
c volume
d opposition

Explanation:

• Weight: It is the force exerted by gravity on an object ($W = mg$), not related to resistance to acceleration from external force.
• Inertial Mass: According to Newton's second law $F = ma$, mass ($m$) represents the body's resistance to acceleration ($a$) when a force ($F$) is applied.
• Volume: It is a measure of the space occupied by an object, has no direct relation to resistance to acceleration.
• Opposition is a very general term and not a specific physical quantity related to the described property.

Answer:

B. Inertial Mass
