Physics and sports

Introduction

Racing

Tennis

Bowling

Cycling

Gymnastics

Friction, Acceleration, Center of Mass, Centripetal Force, Center of Gravity,...

Useage of physics in sport is huge.

RACE CAR

Wide wheel base

low

Centre of gravity and mass

friction Tilt toward the centre

Newton‘s third law

The bigger the radius of the turning circle, the less force needed to make the curve.

The force is directly related to the square of the speed of the car.

Down force is not strong enough

Tennis

„Sweet point“

Center of massLOWER mas of the racket, a greater acceleration is

achived with the same force

Hockey physicsIce hockey

• Easier moving• Less friction

hockey• harder moving• Greater amount or

resistance• Greater force

needed

the resistance to motion of two moving objects or

surfaces that touch

Application of Physics in Gimnastics

Law of Angluar Momentum

TWISTING (less and more moment)

L= (r) (m) (v)

Center of Gravity

POMMEL HORSE

Forces

Newton‘s First Law

RINGS

Newton‘s Second Law

Newton's second law is: F = (m)(a)

Newton‘s Third Law

VAULTING

Wrestling

Newton’s first law

The object will stay:

At rest (if it is at rest)

Moving at a constant velocity (if it is moving)

untill the resultant force acts on the object.

Centre of mass/centre of gravity

Cente of gravity of an object is the point at which we can

take its entire mass to act.

WIDE BASE

LOW CENTRE OF MASS

Swimming

Newton’s third law

If an object A exerts a force on an object B, then the object B

exerts and equal but opposite force on A.

Exerting forces

Swimmer

Object A=Object B

=Water

Weightlifting

Principle of moments

SUM OF CLOCKWISE MOMENTS = SUM OF ANTI-CLOCKWISE MOMENTS

PIVOT

ANTI-CLOCKWISE MOMENTS - BICEPS

CLOCKWISE MOMENTS – WEIGHT OF THE ARM + WEIGHT OF THE HAND
