Kevin’s weight may change between Planet X and Planet Y.
Mass is the amount of matter contained in an object. Gravity is Earth’s pull of a body towards its centre.
Weight (W) is product of the mass (m) of the object and the force of gravity (g) acting on the object.
W = mg
The force of gravity may change between Plant X and Planet Y, and thus Kevin’s weight may change between Planet X and Planet Y.
