1ST LAW - THE LAW OF INERTIA
“A body continues in a state of rest or uniform vel
unless acted upon by an external source”.
If an object is in motion, it keeps going unless som
stops it. If it is resting, it will continue to rest until
something moves it.
No force = no movement
Force = movement
Example forces = Gravity, air resistance, friction,
force

across the net from the force of the hand striking
NOTE: the bigger the mass, the larger the inertia n
