momentum, impulse, intro to biomec

biomechanics

the study of motion and the effects of forces relative to the body. applies the laws of mechanics and physics to human performance.

impulse-momentum relationship

objects can ONLY have momentum when moving, greater the momentum, the more force that needs to be applied to either stop or slow the object down.

momentum

amount of force/motion possesed by a moving body. it is the product of mass and velocity

impulse

application of force over a period of time to change momentum

impulse formula

force x time

momentum formula

mass x velocity

increasing momentum

to maximise the momentum of an object, one must aim to increase both the force and time component.

how are both force and time increased

force is increased through effective summation of force and strength, time is increased through technique

sporting examples for increasing momentum

include sprinting, throwing sports, and weightlifting techniques that utilize explosive movements.

decreasing momentum

to reduce momentum of an object, increase the time component.

sporting examples of decreasing momentum

bungee jumper, cricket fielding, foam inside running shoes
