Hello! I was sitting under this apple tree and noticed that an apple fell down. I wondered why it fell down towards the earth without pulling it. Let us see why/
As we all learnt that it is because of free fall. Free Fall as the term says , the body falling freely because of the gravitational pull of the earth. In simple words we can say that an object with ONLY GRAVITY acting on it.
An apple is a freely falling object. Apple is falling under the sole influence of gravity.All objects will fall with the same rate of acceleration, regardless of their mass
Let us calculate the final velocity when the apple falling at height of 4m/s from rest .
Given: g= 9.8; u= 0; h= 4mTherefore, the final velocity v=8.857m/sTime=0.903 sec
Let me show you an example which may seem like free fall but it is not. Come, let's go!
Let us take a skydiver for example. Even though he is falling freely with the influence of gravity, a parachute is in use, which causes air resistance and a pull, which means that, the gravity is not the only force which is acting upon him in this case
Remember, all objects fall under the same rate regardless of their mass or size. Hope you got it, bye!
