Newton's first law of motion says, An object at rest tends to stay at rest and an object in motion tends to stay in motion with the same speed and in the same direction unless acted upon by any external unbalanced forces.
If we take a look at falling leaf of tree, we will note that the leaf does not come down straight with acceleration 9.78 m/s^2. It rotates in air at the time of falling and takes rather longer time. First, the gravitational pull acts thereby because of the turbulence in the air, the leaf falls.
