Question

How do you calculate velocity if mass is constant?

Answer 1

The mass of an object does not directly affect the calculation of velocity. Velocity is a vector quantity that describes both the speed and direction of an object's motion. It is calculated by dividing the displacement of an object by the time taken to travel that displacement:

$\text{Velocity}=\frac{\text{Displacement}}{\text{Time}}$

The displacement is a vector quantity that represents the change in position of an object, and the time is the duration of the motion.

Mass, on the other hand, is a scalar quantity that represents the amount of matter in an object. It is unrelated to the calculation of velocity. However, mass does play a role in determining the object's acceleration through Newton's second law of motion, $F=ma$, where $F$ is the net force acting on the object, $m$ is the mass, and $a$ is the acceleration.

In summary, velocity is determined by the displacement and time of an object's motion, while mass influences the object's acceleration but not the calculation of velocity.
