Mass doesn't affect speed directly. It determines how quickly an object can change speed (accelerate) under the action of a given force. Lighter objects need less time to change speed by a given amount under a given force.

This article explores the relationship between an object's mass and its speed, explaining how mass influences an object's acceleration and motion. It delves into Newton's Second Law of Motion and provides real-world examples to illustrate the concept.
19 Απρ 2015 · As it turns out, adding mass (while keeping the dimensions of the car fixed) will make the car go faster. This sounds contrary to what all physics students are taught, but the reason is while friction scales with mass, air resistance doesn't. That's why a thirty-foot rock will fall faster than a thirty-foot parachute in an atmosphere.
Investigate the effect of gravity on objects of various masses during free fall. Predict what the position-time and velocity-time graphs will look like. Compare graphs for light and heavy objects.
13 Ιαν 2016 · In the example of the incline plane that you have provided, the mass does not affect the speed, because the only friction force present is proportional to the object's weight. However, oftentimes significant dissipative forces are proportional to the velocity of the object --- for example, if an object if freely falling through a viscous fluid.
Mass affects the velocity of an object in several ways. According to Einstein's theory of relativity, the mass of a body is equivalent to its rest energy, and this is expressed in the formula E0=mc2 [??]. However, there is a common misconception that the mass of a body increases with its velocity, which is not true [??].
Since mass is a scalar, when velocity is in a negative direction (i.e., opposite the direction of motion), the momentum will also be in a negative direction; and when velocity is in a positive direction, momentum will likewise be in a positive direction. The SI unit for momentum is kg m/s.
