The force exerted on an object by Earth's gravity is given by the formula : F = 9.8 m ( not meters it's m ), where F is the force in newtons and m is the mass of the object in kg. How many newtons gravitational force are exerted on a student with a mass with 52kg?

Question

It looks like you just plug in your mass to the formula and multiply it out. Or maybe I overlooked something.

So I just take 52 times 9.8 ?

kainui · Answer

Yeah, that's it, since 52 kg is your mass, when you multiply the acceleration of gravity, 9.8 m/s^2 you get your answer in newtons. A newton is just kg*m/s^2.

wait, I get that I have to that 9.8 times 52 and then what else do I do ?

kainui · Answer

That's about it, you can also consider multiplying the units together too. Just like when you multiply a length times a width, your answer isn't in meters, it's in square meters because you measure area in squares not lines like you do a meter.
