What's the top speed on your car?

[elma22]

Objects will, however, reach a terminal velocity because of drag. If you add mass to the object without altering it's aerodynamic properties, its terminal velocity will rise because your creating more force.

Jimberg, objects falling down can only decrease in velocity, not increase. As you said 10m per second drop is the maximum gravitational pull, which means that objects can only decelerate based on their aerodynamical shape. Regarding my truck speed, every load is distributed over the area differently, putting more weight on the tractor wheels creating more drag. But lets not forget that mass is very important in determining top speed. Every racer works with the weight of their car to determine how much horsepower his engine needs to produce to reach a certain speed. As long as we live on earth, mass will be important. Now once we conquer space, that will be an other question.
Salud to you all.
