Mass
The mass of an object tells us the amount of ‘stuff’ or matter it is made of.
An object’s mass remains the same wherever the object is.
Momentum
If an object is moving, it has momentum. This is what keeps an object moving in the same direction. The more momentum something has, the harder it is to change its direction or bring it to a stop.
Gravity
Gravity is the name of the force that pulls objects together. It is a non-contact force. This means it acts on objects that are not touching each other.
Kepler's Laws: Find the Mass of the Sun
Many years ago, a mathematician named Johannes Kepler created a set of rules explaining planets' movement in our Solar System.
Calculate Your Weight on Another Planet
The 'Space Weight' Calculator
Ever wondered how heavy or light you would feel on another planet in our Solar System?
Gravity Simulator
Is gravity the same everywhere? Experiment with how the ball reacts in each of the Solar System locations by dropping or throwing the ball. How similar or different is each location to Earth?
