Answer to Question #14813 in Mechanics | Relativity for john daqs daquilos
If mass is doubled and the net force is kept constant, what will be the acceleration of the body?
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.
