Can we define a threshold velocity V for an object with mass(rest) M which the object at motion need to attain so that its center of mass accelerates faster than the Dimensional object?
Why do you think the center of mass would accelerate faster than the object itself (assuming that's what you mean)?T.M Masike said:Can we define a threshold velocity V for an object with mass(rest) M which the object at motion need to attain so that its center of mass accelerates faster than the Dimensional object?

Threshold velocity, also known as critical velocity, is the minimum speed required for an object to overcome the resistance of its surrounding environment and continue to accelerate. It is important because it determines whether an object will continue to move at a constant speed or accelerate, and is a crucial factor in understanding the motion of objects.
Threshold velocity is calculated by equating the drag force acting on an object to the force of gravity. This results in the equation V = √(2mg/ρAC), where V is the threshold velocity, m is the mass of the object, g is the acceleration due to gravity, ρ is the density of the fluid, A is the cross-sectional area of the object, and C is the drag coefficient.
The threshold velocity of an object is affected by its mass, the density of the fluid it is moving through, its cross-sectional area, and the drag coefficient. Other factors that may also play a role include the shape and surface texture of the object, as well as any external forces acting on it.
Threshold velocity is the minimum speed required for an object to accelerate, while terminal velocity is the constant maximum speed an object can reach when the drag force balances out the force of gravity. Terminal velocity is often achieved after an object has reached its threshold velocity and continues to accelerate until the drag force and gravity are equal.
Understanding threshold velocity can be useful in various fields, such as engineering, sports, and transportation. For example, engineers can use this concept to design more efficient vehicles, athletes can optimize their movements to reach their maximum speed, and pilots can calculate the necessary takeoff speed for an aircraft.
