Here's why:
* Distance is determined by motion and forces: An object's distance traveled is primarily determined by how fast it's moving (its velocity) and for how long it moves (time). Forces like gravity, friction, or applied pushes/pulls can also influence distance.
* Mass affects acceleration, not distance: Mass does play a role in how easily an object is moved, but not how far it travels. A more massive object will require more force to accelerate to the same speed as a less massive object. However, once both objects are moving at the same speed, they will cover the same distance in the same amount of time.
Example:
Imagine a bowling ball and a feather. The bowling ball has much more mass. If you push both with the same force, the feather will accelerate much faster and travel farther in the same amount of time. However, if you give them both the same initial velocity, they will travel the same distance before coming to rest.
In summary:
* Mass affects how easily an object is accelerated.
* Distance traveled is determined by velocity, time, and forces acting on the object.
