Center mass velocity, also known as center of mass velocity, is the average velocity of an object's mass. It takes into account the different velocities of individual particles that make up the object and calculates the overall velocity of the center of mass of the object.
The center mass velocity can be calculated by dividing the total momentum of the object by its total mass. This can also be expressed as the integral of the mass times the velocity over the entire mass distribution of the object.
Center mass velocity is important because it allows us to analyze the overall motion of an object, particularly in cases where the object is not moving with a constant velocity. It helps us understand how different forces are acting on an object and how it will move as a result.
Average velocity is the total displacement of an object over a period of time, while center mass velocity is the average velocity of the center of mass of an object. Average velocity only takes into account the distance traveled, while center mass velocity takes into account the mass and velocity of the object.
Yes, the center mass velocity of an object can change if there is an external force acting on the object. This can cause the object's mass or velocity to change, which in turn will affect the center mass velocity. However, if there are no external forces acting on the object, the center mass velocity will remain constant.
