Freshman Physics Final Exam Questions and Answers for
the year 2023-2024 Correct
friction
The force that acts to resist the relative motion of objects or materials that are in
contact.
inertia
The property of any body to resist changes in its state of motion. Mass is the measure
of inertia.
Newton's first law
See of law of inertia.
law of inertia
Every body continue is its state of rest,or of motion in a strait line at constant speed,
unless acted upon by a nonzero force. Also known as Newton`s first law.
kilograms
The fundamental SI unit of mass. One kilogram is the amount of mass is one liter of
water at 4 degrees C.See Appendix A.
mass
A measure of an object`s inertia ;also a measure of the amount of matter in an
object.Depends only on the amount of and kind of particles that compose an object not
on it`s location.
weight
The force on a body due to the gravitational attraction of another body.
newton
SI unit of force. One newton is the force applied to one-kilogram mass that will produce
an acceleration of one meter per second per second.
inversely
When two values change directions, so that if one increases the other decrease.
Newton's second law
The acceleration produced by a net on a body is directly proportional to the magnitude
of the net force,and is inversely proportional to the mass of the body.
Free body diagram
a diagram showing all the forces acting on an objet
Newton's third law
whenever one body exerts a force on a second body, the second body exerts an equal
and opposite force on the first
momentum
the product of the mass and the velocity of an object. has magnitude and direction. also
called linear momentum
impulse
product of force and time interval during which force acts. Impulse equals momentum
change
work
the product of the force on an object and the distance through which the object is
moved; measured in joules
, joule
the SI unit of work and of all other forms of energy. One joule of work is done when a
force of one newton is exerted on an object moved one meter in the direction of the
force
power
Rate at which work is done or energy is transformed, equal to the work done or energy
transformed divided by time; measured in watts
watt
the SI unit of power. One watt is expended when one joule of work is done in one
second
energy
the property of an object or a system that enables it to do work; measured in joules.
mechanical energy
The energy due to the position or the movement of something; potential or kinetic
energy.
potential energy
energy of position, usually related to the relative position of two things, such as a stone
and earth, or an electron and a nucleus
kinetic energy
energy of motion, equal to half the mass multiplied the speed squar
crest
one of the places in a wave where the wave is highest or the disturbing is great
trough
one of the places in a wave where the wave is lowest, or the disturbance is greatest,in
the opposite direction from a crest
amplitude
the distances from the midpoint to the maximum of a wave or, equivalently, from the
midpoint to to the minimum
wavelength
The distance from the top of the crest of a wave to the top of the following crest, or
equivalently, the distance between successive identical parts of the wave.
frequency
The number of events (cycles, vibrations, oscillations, or any repeated event) per time,
measured in hertz (or events per time)
hertz
The SI unit of frequency.
transverse wave
A wave with vibration at right angles to the direction the wave is traveling.
longitudinal wave
A wave in which the vibration is in the same direction as that in which the wave is
traveling, rather than at right angles.
interference pattern
A pattern formed by the overlapping of two or more waves that arrive in a region at the
same time
constructive interference
