Laws of Motion
... Newton’s 1st Law: The natural state of an object is to keep its motion A change of motion occurs only if there is net force Inertia = the tendency of an object not to change its motion Mass is quantitative measure of an object’s inertia Newton’s 1st Law is also known as the law of inertia. It w ...

Since we can neglect the masses of the string and the pulley, and the pulley is frictionless the tension at both ends of the string are the same (magnitude T ). Let us assume m2 accelerates down ...
