Question

Define the following terms.
(a) Inertia

(b) Freefall​

Answer 1

Answer:

freefal downward movement under the force only

Answer 2

Answer:

INERTIA

Inertia resists change in motion. Objects want to stay in rest or motion unless an outside force causes a change. For example, if you roll a ball, it will continue rolling unless friction or something else stops it by force.

FREEFALL

In Newtonian physics, free fall is any motion of a body where gravity is the only force acting upon it. In the context of general relativity, where gravitation is reduced to a space-time curvature, a body in free fall has no force acting on it.
