Question

Define :
(i) Free fall
(i) Escape velocity​

Answer 1

Answer:

hello buddy, the following is the answer

Explanation:

Free Fall: In 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.

Escape Velocity: in physics the escape velocity is the minimum speed needed for a free, non-propelled object to escape from the gravitational influence of a massive body. It is slower the farther away from the body an object is, and slower for less massive bodies.

hope it helps you

Answer 2

Answer:

1.In Newtonian physics, free fall is any motion of a body where gravity is the only force acting upon it. ... The term "free fall" is often used more loosely than in the strict sense defined above. Thus, falling through an atmosphere without a deployed parachute, or lifting device, is also often referred to as free fall.

2 the lowest velocity which a body must have in order to escape the gravitational attraction of a particular planet or other object.
