Words and meanings to learn
centre of mass
the point in an object where all its mass seems to be concentrated; it's the point where the object balances evenly in all directions
weight
the force of gravity acting on an object; it depends on the object’s mass and the gravitational field strength
plumbline
a string with a weight at the end, used to find a vertical line or direction; it's often used to locate the centre of mass when an object is suspended
balance
a condition where an object stays steady and doesn’t tip over, usually because its centre of mass is above its base of support
suspended equilibrium
a state when an object is hanging and remains still because its centre of mass is directly below the point of suspension, meaning the object is balanced
