diffrance mass and weight

discussion summary practice problems Summary Weight is the force of gravity on an object. Mass vs. Weight mass weight a measure of inertia (resistance to change in motion) the force of gravity acting on an object due to its mass invariant (does not change with location) variable (depends upon location) scalar (has magnitude only) vector (directed downward) kg (SI base unit) N (SI derived unit)

Weight is the force of gravity

discussion summary practice problems Discussion An interaction between bodies due to their mass. Weight is the force of gravity acting on an object. Derive formula from free fall thought experiment. W = mg Things that weigh a newton. One newton is about halfway between one-fifth and one-fourth of a pound or the weight of one hundred grams. 1 N ≈  101.972 gf or 0.101972 kgf 1 N ≈  ...
