Question

question 10 of 10
what is inertia?
a. the tendency of an object to resist changes in motio
b. the speed of an object
c. the acceleration of an object
d. the ability to move through air

Explanation:

Inertia is a fundamental concept in physics. According to Newton's first law of motion, an object at rest stays at rest and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force. This property of objects to resist changes in their state of motion is called inertia.

• Option B: Speed is a measure of how fast an object is moving, not related to the resistance of change in motion.
• Option C: Acceleration is the rate of change of velocity, not the resistance to change in motion.
• Option D: The ability to move through air is related to aerodynamics, not inertia.

Answer:

A. The tendency of an object to resist changes in motion
