"Velocity and Acceleration". Velocity depends on acceleration, and acceleration is constant during free fall, which is g = 9.81m/Sq.Sec. However Force = mg, Momentum = mv. Therefore these both change with the mass of the object.

Freefall is when the body falls freely under the gravity and we assume, resistance due to the air is negligible. The acceleration on the body is constant and Force on the body is "mg", where "m" is the mass of the body and "g" is the acceleration due to gravity. Since "m" is constant for the given...

Freefall is when the body falls freely under the gravity and we assume, resistance due to the air is negligible. The acceleration on the body is constant and Force on the body is "mg", where "m" is the mass of the body and "g" is the acceleration due to gravity. Since "m" is constant for the given body, the force is also constant. Momentum and acceleration are of course will not be constant when the net force acting on the body is not zero as in the case of free fall. read less
