Answer to Question #75406 in Mechanics | Relativity for jenna

Question

The acceleration of an object is inversely proportional to .....



Remember that directly proportional means that one value increases(or decreases), the other one increases (decreases). In Newton's 2nd law of motion:

F = ma

force is directly proportional to m and a because if either one of them increases, the force increases. If either one of them decreases, the force decreases.

Inversely proportional means that as one increases, the other one decreases....

Answer 1

From newton’s second law, F=ma.making acceleration the subject of the formulae,a=F/m.Hence a ~ 1/m.therefore the acceleration on an object is inversely proportional to mass.
