What is Biomechanics?

• The study of the effects of exercise on the body.

• Biomechanics is the study of the internal and external forces on the human body and the effects produced by these forces

• Isn't a combination of biology, physics and mechanics

• The study of mental strategies to improve athletic performance.

Is force and force summation a key part of biomechanics?

• Yes

• No

What is a major lower body muscle found in the top of your leg ?

What are THREE Major muscles found in the UPPER BODY?

Evaluate responses using AI:

OFF

What are the two terms that affect the angle between two parts of the body?

• Medial and Lateral

• Radius and Ulna

• Anterior and Posterior

• Flexion and Extension

Which of these IS NOT one of Newton's laws?

• Inertia

• F=MxA

• Every object has an equal and opposite reaction!

• Force Summation

What are THREE major Lower Body muscles?

OFF

What is Force Summation?

• The study of forces being added up to create a reactio.

• To obtain or generate maximum force with any movement, many muscles are requires to be used in a well timed sequence

• Force is an external agent capable of changing a body's state of rest or motion.

• An object at rest remains at rest, or if in motion, remains in motion at a constant velocity unless acted on by a net external force

What is the difference between linear and angular motion in biomechanics?

• Linear motion involves movement in a curved path, while angular motion involves movement along a straight path.

• Linear motion involves rotation around an axis, while angular motion involves movement along a straight path.

• Linear motion and angular motion are synonymous terms in biomechanics.

• Linear motion involves movement along a straight path, while angular motion involves rotation around an axis.

What one of Newton's Laws is this?

An object at rest remains at rest, or if in motion, stays in motion unless acted on by a net external force

• Newton's First Law - Inertia

• Newtons Second Law - The Law of Accelleration

• Newton's Third Law - Action and Reaction
