Does mass effect veloctiy?
Actually you’re a little off base. Galileo showed mass doesn’t affect velocity if the motive power is gravity…in a vaccum, a feather will fall as fast from any given height as a bowling ball. Mass becomes a factor in powered accleration…the greater the mass, the greater the force required to accelrate the mass to any given velocity in a set amount of time or distance, this is a factor of inertia. Turn the last statement inside out, and it is true for DEceleration, the greater the mass, the more force it takes to slow the mass in any given amount of time or distance…again, a matter of inetia- a body at rest will remain at rest unless acted upon by an outside force, a body in motion will remain in motion unless acted upon in a like manner. In your example, the greater mass MAY allow the heaver marble to overcome the effects of drag, or surface resistance of the heavier marble as opposed to the lighter, letting it resist the friction of the ramp, and the push of the air it is going
