Two objects with different masses are dropped simultaneously from the same height in a vacuum. What can be said about their acceleration?
Understand the Problem
The question is asking about the acceleration of two objects with different masses when dropped in a vacuum. In a vacuum, there is no air resistance, so the only force acting on the objects is gravity. We need to determine how mass affects acceleration due to gravity in this scenario.
Answer
Both objects will have the same acceleration.
In a vacuum, two objects with different masses dropped simultaneously from the same height will have the same acceleration due to gravity. This acceleration is approximately 9.8 m/s² and is independent of mass.
Answer for screen readers
In a vacuum, two objects with different masses dropped simultaneously from the same height will have the same acceleration due to gravity. This acceleration is approximately 9.8 m/s² and is independent of mass.
More Information
In a vacuum, there is no air resistance, so the only force acting on the objects is gravity. The acceleration due to gravity is constant for all objects, regardless of their mass.
Tips
A common mistake is assuming heavier objects fall faster. This is true in the presence of air resistance, but not in a vacuum.
