Chemical and physical foundations of Biological
systems MCAT REVIEW questions with correct
answers
What does the term force describe? Correct Answer-an outside influence
on an object.


What is a frame of reference? Correct Answer-means that if the
placement of one object is known, it is easier to locate another object
with respect to the position of the original object.


What is speed a measurement of? Correct Answer-an objects movement
or change in position (x), over a change in time (t).


What is the measurement of speed with direction called? Correct
Answer-velocity


What is the equation for velocity? Correct Answer-velocity (v) = delta
(x)/ delta (t)


What is the standard measurement for velocity? Correct Answer-meters
per second (m/s).


What is acceleration a measurement of? Correct Answer-an objects
change in velocity over time.

,What is gravity considered a form of? Correct Answer-acceleration


What is the equation for acceleration? Correct Answer-acceleration (a) =
delta (v)/delta (t).


What is the standard measurement of acceleration? Correct Answer-
meters per second squared. (m/s^2).


What is calculation for momentum? Correct Answer-the calculation of
an object's mass multiplied by its velocity.


What is momentum? Correct Answer-the amount an object wants to
continue moving along its current course.


What is momentum in a straight line called? Correct Answer-linear
momentum.


What is impulse? Correct Answer-the amount of force that acts on an
object during a length of time.


What is the law of inertia?
(Aka Newtons 1st law of motion) Correct Answer-an object in motion
remains in motion, unless acted upon by an outside force. An object at
rest remains at rest, unless acted upon by an outside force.

,What is the law of F=ma?
(Aka Newtons 2nd law of motion) Correct Answer-the force (F) on an
object is equal to the mass (m) multiplied by the acceleration (a) on that
object.


What is Newtons 3rd law of motion? Correct Answer-For every action
there is an equal and opposite reaction.


What are considered as forces? Correct Answer-anything acting upon an
object either in motion or at rest; this includes friction and gravity.


What does a force diagram show? Correct Answer-an object as the focal
point, with arrows denoting all the forces acting upon the object.


When is an object considered to be at equilibrium? Correct Answer-if an
object is at constant motion or at rest (its acceleration is at zero).


Why do two objects dropped at the same time, from the same height,
regardless of mass, theoretically hit the ground at the same time? Correct
Answer-because gravity acts upon both the objects at the same rate.


What factors would make it so that two objects wouldn't hit the ground
at the same time? Correct Answer-shape of the objects as well as air
resistance.

, What is the rate of acceleration that gravity has on every object? Correct
Answer-approx. 9.8 (m/s^2).


What is an axis? Correct Answer-an invisible line on which an object
can rotate.


What is the force causing constant acceleration on or around an axis
called? Correct Answer-centripetal force.


What is the outward force felt when an object is undergoing circular
motion called? Correct Answer-centrifugal force.


What is centrifugal force also referred to as? Correct Answer-fictional
force.


What is centripetal force also referred to as? Correct Answer-true force.


What is the momentum of an object moving in a circular motion called?
Correct Answer-angular momentum.


What does the conservation of angular momentum mean? Correct
Answer-that the angular momentum of a system is always constant,
regardless of the placement of the mass.


What does the term energy refer to? Correct Answer-an objects ability to
perform work.
