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?
- A. Two blocks hit the ground simultaneously because they have the same acceleration
- B. Two blocks reach the ground at the same time because their dimensions are the same
- C. Wooden block being lighter than the steel block reaches the ground first
- D. Steel block reaches the ground first because it is denser than the wooden block
Correct Answer: A. Two blocks hit the ground simultaneously because they have the same acceleration
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.
