One example of Inertia is when I woke up. I did not move for about 20 minutes, and wouldn't have moved if it wasn't for outside forces (A.K.A, my mom.) Another example of Inertia in my daily life is when a pencil falls, because it would keep falling if it wasn't for it hitting the floor. Cars when they stop is a third example.
An example of when keeps moving is a ball rolling down a hill.
An example of when something doesn't move but other things move is a cube on a hill with a bunch of balls which DO roll down the hill.
