M602 Review Questions
Unit 1
1. What do we call the time
rate at which velocity
changes?
Acceleration.
2. What do we call the line,
real or imaginary, that passes
through the center of an object
about which it could rotate? It
is also called a point of
reference.
Axis.
3. What do we call a point
around which an object
rotates?
An axis of rotation.
4. What do we call the amount
of mass contained in a
particular volume?
Density.
5. What do we call the
ability to do work?
Energy.
6. What do we call any action
which tends to produce,
retard, or modify motion; or
change the shape of an
object?
Force.
7. What do we call the action
of one body or substance
rubbing against another; the
resistance to motion of
surfaces touching each other.
Friction.
8. What do we call the
standard measurement of
work used in the United
States?
Foot-pounds.
9. What do we call the force
required to raise 33,000
pounds one foot in one
minute, or 33,000 ft/lbs per
minute. It is used to measure
the power of motors and
engines.
Horsepower.
10. What do we call the opposition of
a body to having its state of rest or
motion changed by an outside force;
the tendency of a body at rest to
remain at rest and a body in motion to
remain in motion, unless acted upon
by an outside force?
Inertia.
11. What do we call the
temperature scale using
absolute zero as the zero
point and divisions that are the
same size increments as
Celsius degrees?
Kelvin scale.
12. What do we call the
energy possessed by an
object because of its motion?
Kinetic energy.
13. What do we call the
quantity of matter in a body as
measured by its resistance to
change in inertia?
Mass.
14. What do we call anything
that occupies space and has
weight?
Matter.
15. What do we call the
branch of physics which deals
primarily with the ideas of
force, mass, and motion and
is usually considered the
fundamental branch of
physics?
Mechanics.
16. What do we call the
tendency of an object to
maintain its given speed and
direction or maintain its
velocity? It may be computed
by multiplying the mass of the
object times its velocity.
Momentum.
17. What do we call the
tendency of an object to
change position over time?
Motion.
18. What explains inertia or
the tendency of a moving
object to resist change in its
state of motion?
Newton’s First Law of
Motion.
19. What states that a change
in motion is proportionate to
the force applied?
Newton’s Second Law of
Motion.
20. What states that whenever
there is a force pushing in one
direction, there is another
force pushing back?
Newton’s Third Law of
Motion.
21. What do we call the
energy of an object before it is
set into motion or released;
stored energy?
Potential energy.
22. What do we call the rate of
doing work measured in footpounds per second, joules, or
watts? When larger measures
are required, the kilowatt and
horsepower are used.
Power.
23. What do we call the
amount of force exerted over
a given area measured in
pounds per square meters or
pounds per square inch?
Pressure
24. What do we call the
greatly reduced friction
created when an object
moves over wheels, rollers,
or balls?
Rolling friction.
25. What do we call the
tendency of an object to turn
around a center point or axis
of rotation?
Rotation.
26. What do we call the rate of
motion of an object over time
without regard to its direction?
Speed.
27. What do we call a force
which tends to produce a
twisting or rotating motion
around a center point or axis
of rotation?
Torque.
28. What do we call the speed
of an object moving in a
particular direction?
Velocity.
29. What do we call the
amount of matter contained in
a particular area often used to
denote the amount of gas or
liquid in a container?
Volume.
30. What do we call the
gravitational attraction the
earth has on an object?
Weight.
31 What do we call the
product of the force exerted
on an object and the distance
it is moved?
Work.
32. What do we call the pull
on all bodies in the earth’s
sphere toward the earth’s
surface?
Gravity.
