What is the difference between mass and weight?

a. the mass of an object is the amount of matter it contains, while its weight is a measurement of the force that gravity exerts on it.
b. the mass of an object is always less than the weight of an object.
c. the mass of an object is directly related to how much gravity there is while its weight is a measurement of how much matter it contains.
d. there is no difference between mass and weight.

Amass attached to a spring is displaced from its equilibrium position by 5cm and released. the system then oscillates in simple harmonic motion with a period of 1s. if that same mass–spring system is displaced from equilibrium by 10cm instead, what will its period be in this case? a mass attached to a spring is displaced from its equilibrium position by and released. the system then oscillates in simple harmonic motion with a period of . if that same mass–spring system is displaced from equilibrium by instead, what will its period be in this case? a) 0.5sb) 2sc) 1sd) 1.4s
