As it’s static before being dropped, so we can take the initial velocity(U) as zero. Say a stone is being dropped from the roof of tall building. That means the objects experiences acceleration which is known in this case as ‘Acceleration due to gravity’.įrom a formula of linear motion, Current Velocity(V) = Initial Velocity (U) + Acceleration due to gravity(g)*Time elapsed (t) Under this force it’s velocity constantly rises till it touches the ground. This is caused by the earth’s pull on the object towards the center of the earth. The object will fall under the influence of a single force, i.e. As we are considering zero air resistance, there is no drag force and as a result no Terminal velocity will be attained. This g varies a bit on different places of earth, but that’s a different story.įor now, we will stick to the value given above, or for simplicity of understanding and quick calculation we may take this as 10 m/sec^2 (Note: For exam follow instructions given in your Question paper for this value on earth) Why velocity of a freely falling body changes considering zero air resistance (ignoring air drag)?Īs an object experiences free fall (considering zero air resistance), the downward force acting on it is its weight itself (mg). The value of g on earth is nearly 9.8 meter/second^2.
When we talk of weight force then the equation becomes like this: Weight(W)= mass * acceleration due to gravity = m * g …… (2) We know the equation of a force = mass * acceleration. The weight of any object is a force applied to the object by the earth’s gravitational pull towards the center of the earth.
