NEWTON’S LAW
The basis for principles used in sports movem
Methods of training depart from these laws a
mechanically.
Tips for efficient sports performances are bui
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
Sporting example:
Volleyball at the highest arc of a server’s toss, tha
motionless. It will either fall straight down due to
across the net from the force of the hand striking
NOTE: the bigger the mass, the larger the inertia n
