What is inertia and orbital motion?

Answer 1

The natural tendency of an object to not move (if it wasn't moving), or to keep moving (if it was moving). Inertia is the characteristic that a object will want to stay at rest or in motion. You can feel this in a buss when it suddenly moves this is why you get sent backwards.

Answer 2

Apparent or perceived resistance to acceleration in a frictionless environment. Force= mass x acceleration, so you need a greater force for a greater mass to get a given acceleration. This effect is often called inertia.

Answer 3

Inertia is the tendency of an object to resist a change in motion. It depends upon the objects mass. If an object has more mass, it is more difficult to get it moving. Once it is moving, it is harder to slow it down.

Answer 4

Inertia-> The tendency of an object to resist a change in motion.

Orbital Motion-> Newtons first law of motion.
