Question

If a stone and a piece of wood are dropped simultaneously from a height in a vacuum, which object will reach the ground first? Why?

Answer 1

1. Both the stone and the piece of wood will reach the ground at the exact same time.
2. Because in a vacuum, there is no air resistance. The only force acting on both objects is gravity, which means they are in a state of free fall. The acceleration due to gravity is a constant value for all objects, regardless of their mass, size, or material. Since they both start from the same height with zero initial velocity and accelerate at the exact same rate, they will hit the ground simultaneously.
