* In a vacuum: In the absence of air resistance or other forces, a heavy and a light object will fall at the same rate. This is because gravity accelerates all objects equally, regardless of their mass. Think about dropping a feather and a hammer on the moon – they'll hit the surface at the same time!
* With air resistance: In the real world, air resistance plays a big role. A heavy object with a small surface area (like a bowling ball) will encounter less air resistance and will fall faster than a light object with a large surface area (like a feather).
So, to answer your question:
* Without air resistance: They travel at the same speed.
* With air resistance: The heavier object will likely travel faster.
Important Note: This is about falling objects. If you're talking about things like rockets or cars, the heavier object would generally require more energy to accelerate and might be slower to reach a certain speed.
