Question

State Newton's first law of motion. What do you understand by inertia? Describe in an experience you have had in which inertia was involved.

Answer 1

If the net force is zero, the body will move by inertia along a straight line at constant velocity or rest. Inertia is the measure of the effort that I need to make to change the motion of an object. I had such an experience when was sliding on a frozen lake.
