Does centre of mass depend on coordinate system?
(A) The position of centre of mass of a system is dependent on the choice of co-ordinate system. (C) When no external force acts on a body, the acceleration of centre of mass is zero.
Is the center of mass independent of the choice of coordinate system?
A. The mass distribution of the body determines the position of centre of mass. Therefore, the centre of mass is independent of the coordinate system.
Why does the location of the centre of mass change?
Center of mass and motion The velocity of the system’s center of mass does not change, as long as the system is closed. The system moves as if all the mass is concentrated at a single point. The final location will be at the weighted distance between the masses.
Does the measurement of position depend on the choice of coordinate system?
Position itself is a vector and its mathematical representation will depend on the coordinate system chose to describe the motion.
Do internal forces affect the position of centre of mass of a system of particles?
Answer: The system of particle on different particles, internal forces do not effect on motion of center of mass.
What is centre of mass state its position coordinates?
The center of mass is a position defined relative to an object or system of objects. It is the average position of all the parts of the system, weighted according to their masses. For simple rigid objects with uniform density, the center of mass is located at the centroid.
What is Centre of mass state its position coordinates?
Do internal forces affect the position of Centre of mass of a system of particles?
Why does the center of mass not move?
The books states the answer as: “There is no interaction outside the system (no external force), therefore the center of mass will not move.”
What is position of center of mass?
How positive and negative positions are determined?
When the object moves to another position, its displacement is the second position minus the first position. If one follows the rule of always subtracting the first position from the second, the sign always works out to be positive if the displacement is to the right and negative if the displacement is to the left.
How an object can have a negative position in a coordinate system?
If an object is moving in the +x direction, and it is slowing down, then the slope of the graph is negative.
Why is the center of mass independent of coordinate system?
Also the position of center of mass is determined by the mass distribution in the body, hence being independent of coordinate system. Was this answer helpful?
Does the position of the center of mass depend on distance?
The position of centre of mass only depend upon shape size and distribution of mass within the body. So centre of mass doesn`t depend on distance between the particles
Which forces can change the state of the center of mass?
(D) Internal forces can change the state of centre of mass. Acceleration of center of mass occurs due to external forces acting on the body only. Hence statements B and C are correct and statement D is wrong.
What is the definition of center of mass?
It is the average position of all the parts of the system, weighted according to their masses. For a simple rigid object which has a uniform density, the center of mass is located at the centroid.
