# Why will a baseball and a marble fall at the same rate?

## Why will a baseball and a marble fall at the same rate?

For example, if you ask someone what would fall faster, a bowling ball or a marble, I bet a lot of folks would say the heavier bowling ball falls faster. But in fact, if dropped from a meter or so off the ground, they’d fall at the same rate. Gravity accelerates them at the same rate, so they fall at the same rate.

### Which ball will hit the ground first if dropped at the same time and at the same height in a perfect vacuum?

Therefore, when both objects are dropped from the same height and at the same time, the heavier object should hit the ground before the lighter one.

#### Why does a heavier object fall with the same acceleration as a lighter object *?

Acceleration of Falling Objects Heavier things have a greater gravitational force AND heavier things have a lower acceleration. It turns out that these two effects exactly cancel to make falling objects have the same acceleration regardless of mass.

What is Galileo’s law of motion?

Galileo’s claim that force causes acceleration is inseparable from his claim that bodies do not require a cause to continue their movement. This latter claim states that a body in motion will continue its motion so long as no factor disturbs that motion. This principle is called the principle of inertia.

What will happen if you drop a golf ball a baseball and a bowling ball at the same instant from the top of a building?

What will happen if you drop a golf ball, baseball, and a bowling ball at the same instant from the top of a tall building? All three balls will hit the ground at the same time.

## Why do two objects fall at the same time?

Consequently, the acceleration is a=Fm=GMR2, which is independent of the mass of the object. Hence any two objects that are subject only to the force of gravity will fall with the same acceleration and hence they will hit the ground at the same time.

### What happens when two objects of different masses are dropped from the same height?

Because Earth gives everything the exact same acceleration, objects with different masses will still hit the ground at the same time if they are dropped from the same height. The less massive the object is, the more the force of air resistance slows the object down as it falls.

#### What will happen if a lightweight object and a heavyweight object bump to each other?

A: There is an equal and opposite force on each of the two objects: they will both move. Now since the acceleration of each object is inversely proportional to the mass, the lighter object will move a bit faster. If you do the arithmetic you will find that they will meet at their common center of mass.
