Q

What does it mean if a body is dynamic?

A

It means that the body is moving; this either means there is an increase/decrease in speed or change in direction.

Q

What is the difference in Mass and Weight?

A

Mass is the quantity of matter that never changes. Weight is the force exerted due to gravity.

15
Q

What is center of gravity?

A

a hypothetical point around which the force of gravity appears to act

16
Q

What is Newton’s First Law?

A

an object in motion stays in motion, an object at rest stays at rest unless acted on by an external force

17
Q

What is Newton’s Second Law?

A

F=ma

18
Q

What is Newton’s Third Law?

A

For every action, there is an opposite and equal reaction

19
Q

What is a vector?

A

a measurement with magnitude and direction

20
Q

What is a scalar?

A

a measurement of only magnitude, not direction

21
Q

What is Wolff’s Law?

A

“Every change in the form and function of a bone or of their function alone is followed by certain definitive secondary alteration in their external confirmation, in accordance with mathematical laws”
or
Tissues adapt to levels of imposed stress.
