... • The sum of all the Forces acting on the system is equal to the total mass of the system times the acceleration of its center of mass. • The center of mass of a system of particles (or objects) with total mass M moves like a single particle of mass M acted upon by the same net external force. ...

Newton`s Law of motion 1
... Gravitational mass is measured by such method, e.g. spring balance. Measuring the mass (inertia mass) Mass can be defined as the ‘ amount of matter’ in an object. But considering Newton’s 2nd Law of motion, m = FN / a, mass has a new meaning – “Inertia”. Inertia is the resistance of an object to a c ...

Wood on wood would have a different frictional force than steel on wood, and so on. Heavy objects have more friction than very light ones, etc. • When an object is at rest, it takes a ...
