Answer to Question #14813 in Mechanics | Relativity for john daqs daquilos

Question

If mass is doubled and the net force is kept constant, what will be the acceleration of the body?

Answer 1

Let's consider the second Newton's law:

F = ma& ==> a = F/m.

Now let's double the mass:

F = 2ma ==> a = F/(2m).

We can see that acceleration decreases by two times.
