Two blocks of the same dimension, one steel and the other wooden are dropped simultaneously from the same height. If they fall freely neglecting air resistance the?
-
Two blocks hit the ground simultaneously because they have the same acceleration
- Two blocks reach the ground at the same time because their dimensions are the same
- Wooden block being lighter than the steel block reaches the ground first
- Steel block reaches the ground first because it is denser than the wooden block
- Steel block takes half as much time as the wooden block to reach the ground because it is more massive than the wooden block
The correct answer is: A
Explanation
An object falling without air resistance or friction is defined to be in free-fall.
The acceleration of free-falling objects is therefore called the acceleration due to gravity.
It is because the acceleration due to gravity is constant for all objects regardless of the mass, neglecting air resistance.
