Newtons Laws Of Linear Motion Flashcards
What is sports biomechanics?
Scientific study that applies principles of;
1.mechanics
2.physics
to analyse human movement
1.sports
2.athletic activities
Give 3 of newtons law to improve performance
1.Understanding movement patterns
2.Optimising performance
3.preventing injures
What is ‘understanding movement patterns” in newtons laws to improve performance
How objects accelerate,decelerate and change of direction
What is “optimising performance” in newtons laws to improve performance
Maximise force production, minimise energy expenditure and enhance movement efficiency
What is “preventing injuries” in Newtons law to improve performance
Reducing risk factors, such as;
1.excessive forces
2.poor technique
3.inadequate equipment
What is the name of the FIRST LAW in newtons law?
Law of inertia
What is the name of the SECOND LAW in newtons laws?
Law of acceleration
What is the name of the THIRD LAW of newtons laws?
Law of action and reaction
What is Newton’s first law (law of inertia)?
Object will continue in state of rest or motion in a straight line unless acted upon by a external force
What is Newton’s second law (law of acceleration)?
Acceleration of an object is dependent upon two things
1.net force
2.mass
What is Newton’s third law (law of action and reaction)
Every reaction there is an equal and opposite reaction
What is economy of movement ?
How efficient or energy sparing an athlete is when they are moving
What is energy systems?
Athlete is more efficient with movement and their body will use less oxygen and fatigue less
