Question

Two objects of different masses falling freely near the surface of moon would :

Options

• have same velocities at any instant

• have different accelerations

• experience forces of same magnitude

• undergo a change in their inertia

Answer 1

have same velocity at any instance
We know,
v = u + at
⇒ v = 0 + gt
[Here, g is acc. Due to gravity on moon]
Thus, the equation of velocity for a freely falling body is independent of the mass of the body.
So, different masses that are dropped simultaneously with the same or zero initial velocity will have same velocity at any instant.
