MCAT REVIEW || with Complete Solutions.
What does the term force describe? correct answers an outside influence on an object.
What is a frame of reference? correct answers 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 answers an objects movement or change in position (x),
over a change in time (t).
What is the measurement of speed with direction called? correct answers velocity
What is the equation for velocity? correct answers velocity (v) = delta (x)/ delta (t)
What is the standard measurement for velocity? correct answers meters per second (m/s).
What is acceleration a measurement of? correct answers an objects change in velocity over time.
What is gravity considered a form of? correct answers acceleration
What is the equation for acceleration? correct answers acceleration (a) = delta (v)/delta (t).
What is the standard measurement of acceleration? correct answers meters per second squared.
(m/s^2).
What is calculation for momentum? correct answers the calculation of an object's mass
multiplied by its velocity.
What is momentum? correct answers the amount an object wants to continue moving along its
current course.
What is momentum in a straight line called? correct answers linear momentum.
What is impulse? correct answers 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 answers 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 answers 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 answers For every action there is an equal and
opposite reaction.
What are considered as forces? correct answers anything acting upon an object either in motion
or at rest; this includes friction and gravity.
What does a force diagram show? correct answers 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 answers 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 answers 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
answers shape of the objects as well as air resistance.
What is the rate of acceleration that gravity has on every object? correct answers approx. 9.8
(m/s^2).
What is an axis? correct answers an invisible line on which an object can rotate.
What is the force causing constant acceleration on or around an axis called? correct answers
centripetal force.
What is the outward force felt when an object is undergoing circular motion called? correct
answers centrifugal force.
What is centrifugal force also referred to as? correct answers fictional force.
What is centripetal force also referred to as? correct answers true force.
What is the momentum of an object moving in a circular motion called? correct answers angular
momentum.
What does the conservation of angular momentum mean? correct answers 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 answers an objects ability to perform work.
What is energy usually measured in? correct answers joules.
, What is potential energy? correct answers stored energy, or energy due to an objects height
above the ground.
What is kinetic energy? correct answers energy of motion.
What is mechanical energy? correct answers is the sum of potential and kinetic energy in a
system, minus energy lost to non-conservative forces.
What is thermodynamics? correct answers the study of heat and movement.
What is the fundamental law of thermodynamics called? correct answers conservation of energy.
What is the law of conservation of energy? correct answers energy is neither created nor
destroyed, but rather, energy is transferred to different forms.
What are fluids? correct answers liquids and gases.
What is pressure? correct answers weight of block/ area of base.
What is buoyant force? correct answers a net upward force on the bottom of a block due to the
pressure of the water acting on that surface. this counteracts the weight of the block.
What two conditions would cause a block to sink to a depth such that the buoyant force of the
water just matches the total weight of the block? correct answers 1)the body of water is deep
enough to float a block.
2)the density of the block is less than the density of water.
What would cause the block to be beached? correct answers if the water is not deep enough.
What would cause the block to sink? correct answers if the density of the block is greater than
the density of the fluid.
What is weight and balance of a vessel called? correct answers trim.
What is the hull? correct answers Body of a boat that displaces a volume of water.
What are ballast tanks? correct answers void spaces that are hollow in bottom of boat.
How could a less denser liquid float on a denser liquid? correct answers if they are immiscible.
What does it mean to be immiscible? correct answers does not mix.
What is Pascal's Law? correct answers states that a change in pressure, applied to an enclosed
fluid, is transmitted undiminished to every portion of the fluid and to the walls of its containing
vessel.
