1 Answer

Answer :

1st formula: All objects falling from a fixed position and the same height without any obstruction cross the same path at the same time. 2nd law: The velocity of an object falling from a fixed position without any hindrance at a given time is proportional to that time. That is, vµt 3rd law: The distance covered by a falling object from a fixed position at a given time is proportional to the square of that time. I.e. hµt2

Why does falling on sand from the same height cause less injury than hard floor ?

Description : Why does falling on sand from the same height cause less injury than hard floor ?

Last Answer : Falling on sand from the same height causes less injury than hard floor. Reason: When a person falls on a hard floor from above, the floor pushes backwards as a reaction on the person. Since the floor ... the person move a little downhill easily. So it hurts less to fall on sand than on hard floor.
