Question

A freely falling body moves with a
A. constant speed
B. constant velocity
C. constant acceleration
D. varying acceleration

Answer 1

Hint: In Newtonian Physics, free fall is a phenomenon referred to as any type of motion of an object where gravity is the only force felt there.
But when we analyse the problem in the concept of general relativity, where gravitation is discussed in space time curvature, a body in free fall has no force acting on it.

Complete answer:
 

In a roughly uniform gravitational field, when there is no other forces acting, gravitation will be experienced on each part of the body roughly equally, which will cause like the feeling of weightlessness, a situation that also happens when the gravitational field is weaker like the object far away from any source of gravity. In the context of general relativity, an object in free fall is not experiencing any kind of forces and is an inertial object moving along a geodesic. The Newtonian theory of free fall agrees with general relativity, at far away from any sources of space-time curvature. Here the space time will be flat. As there is no force acting, then the acceleration will be zero. Mass cannot be zero anyway. Therefore we can say that as the acceleration is zero, the body will be moving in a constant velocity.
$\begin{align}
  & a=\dfrac{\Delta V}{\Delta t} \\
 & a=0\Rightarrow \Delta V=0 \\
 & V=\text{constant} \\
\end{align}$

So, the correct answer is “Option B”.

Note:
An object in the sense of the free fall will not be falling down in the common sense of the term for sure. An object which is in a motion upward will not normally be viewed to be falling, but if it is acted by the force of gravity only, then the object is said to be in free fall. The moon is said to be in free fall.
