Mass, Weight and Free Fall

Name: Mass, Weight and Free Fall
Author: StemPy Lab

Your mass is the same on the Moon, but your weight is not. Why? In this course we separate mass from weight, and we weigh an astronaut on the Moon and on Jupiter. Then we see what happens when only gravity acts, in free fall and in an orbit.

Lesson 1about 20 min
Free fall and motion under gravity
In free fall, only gravity acts. Every falling object speeds up by g in every second, and the equations of motion work with a = g.

Lesson 2about 20 min
Mass and weight
Mass is how much matter an object has. Weight is the pull of gravity on it. Mass stays the same everywhere, but weight does not.

Lesson 3about 25 min
Weight on the Moon and other planets: orbits and weightlessness
Weight is smaller on the Moon and bigger on Jupiter. A satellite is always falling round the Earth, so its crew feels weightless.
