Newton’s Laws
1. The law of inertia.
“ a body continues in a state of rest or uniform motion unless
a unbalanced force acts upon it”
2. The Law of acceleration
“ the more force used to move an object, the larger it’s
acceleration will be in the direction it was applied.
Force= mass x acceleration
3. Law of reaction
“ for every action there is an equal and opposite reaction”
E.G pushing into the floor to make a jump into the air.
Force summation
The amount of momentum given to the object is
determined by the sum of all forces generated
by each body part. – force summation
To gain maximum momentum the
force needs to be generated by:
• Using as many segments of the body as
possible
• Using muscles in the correct sequence, using
large muscles first then the smaller faster
ones.
• Correct timing
• Greatest range of motion
Jumping smash
Starts with movement from the legs pushing
down into the ground ( Law…..)
This force is then returned up through the legs (
equal and opposite reaction) at the same time
the arm is extended, power transfers through
the forearm to the wrist.
Projectile Motion
• As soon as an object is in motion is becomes a
projectile.
Angle of release
• Can be applied to the Smash, long serve and
over head clear.
• The greater height you can reach the steeper
the angle = more force
Height affects angle of release.
More height more power and
speed = force
