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?
