Question

What do you mean by free fall ?The mass of an object is 10kg what is its weight on the earth.

Answer 1

The motion of a body which happens only under the influence of gravity is known as free fall. During free fall only gravitational force is acting on the body. 

Mass(m) = 10Kg
Gravity of earth(g) = 9.8m/s^2
Weight = mg = 10*9.8 = 98 N (N is unit of weight and it denotes Newton)

Answer 2

Answer:

In Newtonian physics, free fall is defined as the motion of an object where gravity is the only force acting upon it. ... A skydiver may be pulled towards earth by gravity, but they are also affected by air resistance, a force opposing their downward movement.
