Intro to Biomechanics

What is biomechanics?

• The study of living things from a mechanical perspective

• The study of chemical reactions in the body

• The study of nutrition and diet

• The study of mental health in sports

The difference between mass and weight is?

• one takes into account gravity & the other doesn't

• one is affected by velocity and the other by speed

• there is no difference

• one is measured in kilograms and the other in litres

What is the role of biomechanics in sport?

• To study the human body

• To produce optimal performance

• To analyse coaches and their strategies

• To create robots to bring oranges at half time

What is kinematics concerned with?

• The push and pull of forces

• The description of motion

• The amount of matter in an object

• The study of human anatomy

Biomechanics studies forces that are:

• Only internal

• Only external

• Both internal and external

• Neither internal nor external

Which of the following is NOT true about Friction?

• occurs when 2 surfaces are in contact

• is decreased by wearing studs on the bottom of your shoes

• is decreased by sharpening your ice skate blades

• is important so you don't slip off your surfboard

Which of the following statements is true about mass?

• Mass changes with location

• Mass is constant

• Mass is a force

• Mass is measured in newtons

The reluctance of a body to change it's state of motion is known as?

• Speed

• Inertia

• Distance

• Mass

Which of the following is NOT a type of external force?

• Gravitational force

• Frictional force

• Muscle contraction

• Air resistance

Force is described as..

• the opposite of inertia

• the amount of matter in a body

• mass x velocity

• A push or pull
