Question

Rebecca is pushing her motorcycle down the road to a repair shop with a certain net force. If the net force is doubled, by how much does the acceleration change?

Answer 1

If the net force is doubled the acceleration change in the same proportion, that is to say, it is doubled too.

Step-by-step explanation:

We have that:

`F = ma`

From the equation above we see that the acceleration is directly proportional to the force, so hence if the force is doubled:

`F_(1) = ma_(1)`

`2F_(1) = ma_(2)  \rightarrow a_(2) = 2(F_(1))/(m) = 2a_(1)`

Therefore, If the net force is doubled the acceleration change in the same proportion, that is to say, it is doubled too.

I hope it helps you!
