Batting is momentum between objects moving in different directions. Momentum is conserved when:

Pre-impact of ball & bat = post-impact of ball & bat

Giving with the ball, increases the length of time over which force acts on the ball means:

the force exerted during the catch is reduced

An example of using impulse to safely decrease momentum would be

a high jumper using a crash mat to land safely

Newtons laws
Stability
Force summation
Projectile motion
7
COG, BOS and LOG all refer to what basic biomechanics concept?
Balance

8
Giving with the ball, increases the length of time over which force acts on the ball means:
there is less chance the ball will be dropped by the catcher
the player has more time to get in position to catch
the velocity of the ball remains constant
the force exerted during the catch is reduced

True
False
11
The most stable position for a rugby player to take in preparation for tackling an oncoming opponent is:
stand straight and lean forward

The change in momentum experienced by an object is always equal to its:
change in time
change in force
impulse
change in velocity
13
For the Olympic event the Hammer Throw, what biomechanical principle is most important?
Impulse
Newton's 1st Law
Newton's 3rd Law
Sequential Force Summation
14
An example of using impulse to safely decrease momentum would be
a gymnast landing with straightlegs following a vault.
moving forward to block a punch in tae kwon do.
catching a ball at arms distance from the body.
a high jumper using a crash mat to land safely
15
