Question

11. An object accelerates 7.2 m/s?when a force of 4.0 newtons is applied to

it.
What is the mass of the object?

Answer 1

0.56 kg

Step-by-step explanation:

F = ma. Force = Mass x acceleration

Let's take a look at why that works. If something has more mass ie atoms then it will require more effort to move it. If you want make something speed up at a higher rate then again you need to provide more of an effort. Therefore you need more force for both these situations.

Therefore the equation works.
