KNS 200 Exam 2 Question and
answers rated A+ 2025/2026
Biomechanics - correct answer ✔________ is the applications of mechanical principles to understand
effects of forces on physical functions and structures.
Mechanics - correct answer ✔_______ is a branch of physics that studies motion (kinematics_ that the
causes of motion (kinetics).
Displacement - correct answer ✔The formula for ______ is the final position minus the initial position.
(unit: meters)
Velocity - correct answer ✔The rate of change in a position is the ______.
Acceleration - correct answer ✔A rate of change in velocity is _______.
Mass - correct answer ✔______ is a quantity of matter in the body; inertia. (unit: kg)
Force - correct answer ✔______ is a push or pull, friction, gravity, or air resistance. The formula for this
is mass x acceleration.
External - correct answer ✔An _______ force is applied by another object (ground or another person).
Internal - correct answer ✔An _______ force is forces generated inside the body.
Inertia - correct answer ✔Newton's 1st law, the law of ______, states that an object at rest will stay at
rest unless there is a force to cause it to move.
, 1st - correct answer ✔Newtons ____ law, the law of inertia, states that an object in motion will
continue that motion (direction and speed) unless there is a force to cause it to change.
Acceleration - correct answer ✔Newton's 2nd law, the law of _______, states that the change in
motion of an object is proportional to the force applied.
2nd - correct answer ✔Newton's ____ law, the law of acceleration, states that the change in motion is
in the direction that the force is applied.
3rd - correct answer ✔Newton's ____ law, the law of action and reaction, states that for every action
force, there is an equal (in magnitude) and opposite (in direction) reaction.
Harvard fatigue lab - correct answer ✔The first exercise physiology lab in the U.S. that focused on
fatigue, altitude, and temperature was called the ________ _______ ______.
Eisenhower - correct answer ✔President ______ encouraged more physical fitness after a heart attack
in the 1950's.
Energy - correct answer ✔Adenosine triphosphate (ATP) is used for ______.
4 - correct answer ✔A carbohydrate is about ____ kcals/gram.
9 - correct answer ✔A fat is about ____ kcals/gram.
4 - correct answer ✔A protein is about _____ kcals/gram.
