The center of mass is the point in an object or system where its mass can be considered to be concentrated. It is the average position of all the parts of the object, weighted according to their masses.
Imagine a seesaw with different objects placed on each end. The center of mass is like the balancing point on the seesaw where you could place your finger and keep it perfectly balanced.
Torque: Torque refers to the twisting force that causes an object to rotate around an axis. It depends on both the force applied and the distance from the axis.
Equilibrium: Equilibrium occurs when all forces acting on an object are balanced, resulting in no net acceleration or movement.
Moment of Inertia: Moment of inertia measures an object's resistance to changes in rotational motion. It depends on both its mass distribution and how it is rotating.
A shopping cart has three wheels that roll on frictionless bearings, but one of the side wheels A (left) or B (right) has significant friction. When a force F is applied to the handle as shown, the center of mass of the cart speeds up and the cart turns to the left. Which wheel has friction, and is the friction greater or less in magnitude than F?
An object is made up of a solid cap and a solid base. The base is four times heavier then the cap. Is the center of mass closer to the base or the cap?
