If one bullet has twice the mass of the other, the ratio of the speed of the lighter bullet to the speed of the heavier depends upon the velocity of the bullets too. The mass of an object does not change the speed. It changes only if we cut or add to that object.
How does mass affect speed of an object?
- 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.
- Alternatively, mass determines how strong a force has to be to accelerate an object at a given rate. Lighter objects can do with weaker force to change speed by a given amount in a given amount of time.
- Thus, mass is a measure of object's inertia which is resistance to changes in object's motion. This is what the equation
F=ma
means,
- That speed is relative (i.e. depends on the choice of the frame of reference) and, in the framework of Newtonian mechanics, for each object there is a frame of reference in which it is moving at arbitrarily high velocity.
