Question

What is the weight of a body of mass 12 kg? What is the force acting on it? (g = 10 m/s^2)​

Answer 1

The equation for Force is: Force = mass x acceleration, or F=ma for short. It's definitely a useful one to remember if you can.

We've been told that g = 10 meters per second^2, which is the acceleration of the Earth's gravitational field.

So we have our mass, and our acceleration. We can then use F=ma, 12kg x 10ms-2 to work out our Force, 120N

Weight is a type of force, which we get when we do mass x gravitational acceleration, so the two answers are the same!

Weight = 120N

Force acting on the body is also 120N down (with 120N pushing up if it's still)

If the body is not moving, there'll be a force acting opposite to gravity as well. For example, if our 12kg body is sitting on a table pushing down with 120N of force, the table will push back on the body with 120N.

Answer 2

Weight = (12×9.8 )= 117.6 N
