Question

quiz: newtons first law of motion
which statement is the best definition of inertia?
o objects in motion resist gravity.
o objects resist changes in their state of motion.
o objects in motion resist changes in acceleration.
o objects at rest easily start to move.

Explanation:

Inertia is the property of matter by which it continues in its existing state of rest or uniform motion in a straight line, unless that state is changed by an external force. This means objects resist changes in their state of motion. The other options are incorrect - objects in motion do not resist gravity as a definition of inertia, objects in motion resist changes in velocity not just acceleration, and objects at rest do not easily start to move due to inertia.

Answer:

Objects resist changes in their state of motion.
