KAAP350 - Unit 3 Biomechanics Part 2

Who formulated the laws of motion?

• Albert Einstein

• Galileo Galilei

• Sir Isaac Newton

• Nikola Tesla

What does Newton's First Law of Motion, also known as the Law of Inertia, state about an object in motion?

• An object in motion will change its velocity every minute.

• An object in motion will not change its state unless acted upon by an external force.

• An object in motion will stop eventually without an external force.

• An object in motion does not require any force to keep moving.

What is inertia according to Newton's First Law of Motion?

• The ability of a body to increase its velocity.

• The tendency of a body to resist changes to its state of motion due to its mass.

• The force required to keep a body in motion.

• The energy a body possesses due to its motion.

What does Newton's Second Law of Motion state about the relationship between force, mass, and acceleration?

• Force equals mass divided by acceleration

• Force equals mass plus acceleration

• Force equals mass times acceleration

• Force equals the square of mass times acceleration

What does Newton's Third Law of Motion state?

• For every action, there is an equal and opposite reaction.

• For every action, there is a lesser reaction.

• For every action, there is a greater reaction.

• For every action, there is no reaction.

What is a characteristic of angular motion?

• It involves a straight path

• It does not require an axis

• It must have an axis of rotation

• It follows a curved path

Which type of motion is described by a straight path?

• Angular

• Curvilinear

• Rectilinear

• Circular

What describes curvilinear motion?

• Motion along a straight line

• Motion that requires an axis of rotation

• Motion along a curved path

• Random motion

What is General Motion in the context of human movement?

• Movement that involves only linear motion

• Movement that involves only angular motion

• A combination of linear and angular motion

• Movement that does not involve joints

How is linear translation of the body through space accomplished?

• Through linear motions only

• Through angular rotations about the joints

• Through external forces only

• Through stationary positioning of the body
