Center of Mass
It is the location in space where a force that is applied to the system will make it move without tendency to rotate
Geometric center
On solving the center of mass of an object, the geometric center must be first located
Geometric center
It is also known as the physical center of the object
The masses that constitutes objects of the system
The location of the objects in arbitrary coordinate system
2 factors to determine center of mass
uniform composition (homogeneous)
A system that has ____, has its geometric center as its center of mass
force
When force is applied to the center of mass, the object as a system of particles moves in the direction of ____ without rotating
center of mass
No matter what the shape of the object, this helps understand the mechanism of force and motion of that object
Momentum
It is the product of mass and velocity
Momentum
Sometimes called inertia in motion
Momentum
It combines the idea of inertia and motion
kg m/s
Unit of Momentum
Impulse
It is the product of force that acts on a body at a given time
Newton seconds
Unit of Impulse
Impulse-Momentum Theorem
It states that when a force acts on the body it produces a change in momentum
Law of Conservation of Linear Momentum
It states that in an isolated system where the external net force is zero, the total momentum of the system is constant
