KNS 200 Exam 2 Question and
answers 100% correct 2025/2026
_____ is the applications of mechanical principles to understand effects of forces in physical functions
and structures - correct answer ✔biomechanics
_____ is a branch of physics that studies motion and the causes of motion - correct answer
✔mechanics
what is the study of motion? - correct answer ✔kinematics
what is the causes of motion? - correct answer ✔kinetics
____ is the difference between initial and final positions - correct answer ✔displacement
what is the displacement formula? - correct answer ✔d = d(final) - d(initial)
what is the unit for displacement? - correct answer ✔meters
_____ is the rate of change in position - correct answer ✔velocity
what is the formula for velocity? - correct answer ✔v = (d(final) - d(initial)) / change in time
what is the untis for the velocity formula? - correct answer ✔meters per second
_____ is the rate of change in velocity - correct answer ✔acceleration
,what is the acceleration formula? - correct answer ✔a = (v(final) - v(initial)) / change in time
what are the units for the acceleration formula? - correct answer ✔meters per second squared
____ is inertia (the quantity of matter in a body) - correct answer ✔mass
what are the units for mass? - correct answer ✔kg
_____ is a push or a pull - correct answer ✔force
what is the force formula? - correct answer ✔F = m(a)
m = mass
a = acceleration
what are the units for the force formula? - correct answer ✔newtons
what are some examples of force in nature? - correct answer ✔friction, gravity, air resistance
what are the 2 types of forces? - correct answer ✔external forces & internal forces
_____ forces are applied by another object (ground, another person, equipment) - correct answer
✔external
_____ forces are generated inside the body - correct answer ✔internal
, what is an example of a force we apply to another object? - correct answer ✔archery
forces _____ and _____ movement - correct answer ✔generate, control
T or F: Forces maintain, protect, and improve the health of body tissues/systems - correct answer
✔true
T or F: Small changes in posture have large effects on our body - correct answer ✔true
what are newton's 3 laws of physics? - correct answer ✔(1st) law of inertia
(2nd) law of acceleration
(3rd) law of action & reaction
what do these laws tell us? - correct answer ✔how to generate forces and how forces affect structure
and function
what is the law of inertia? - correct answer ✔an object at rest will stay at rest unless there is a force to
cause it to move
an object in motion will continue that motion (direction and speed) unless there is a force to cause it to
change
what is force during law of inertia? - correct answer ✔F = 0
what is the law of acceleration? - correct answer ✔the change in motion of an object is proportional to
the force applied
