If an object has a mass of 50 kg, what is its weight?

Weight is given by the formula,

`W=mg`

• `W` is the weight of the object in newtons

• `m` is the mass of the object in kilograms

• `g` is the gravitational acceleration

On Earth, `g=9.8 "m/s"^2`. So, the object's weight on Earth will be:

`W=50 "kg"*9.8 "m/s"^2`

`=490 "N"`

Can you tell what the object's weight will be on another planet, such as Mars?
