Question

if the body of mass m is released in gravitational field with gravitational acceleration g . then find the velocity of a body after time t seconds. Given:The initial velocity of body is u.
​

Answer 1

Answer:

A set of equations describe the resultant trajectories when objects move owing to a constant gravitational force under normal Earth-bound conditions. For example, Newton's law of universal gravitation simplifies to F = mg, where m is the mass of the body. This assumption is reasonable for objects falling to earth over the relatively short vertical distances of our everyday experience, but is untrue over larger distances, such as spacecraft trajectories.
