missing work DUE WEDS. 3. Which are examples of constant velocity?
Gravity, a toy car on a ramp, a book still on a table, a hockey
puck sliding across ice, a NASCAR pace car... constant velocity?
acceleration? ACCELERATION OCCURS WHEN SPEED OR DIRECTION OF SPEED
ARE CHANGING. IF POSITION CHANGES BUT NOT DIRECTION OR SPEED (RATE
OF CHANGE) YOUVE GOT CONSTANT VELOCITY... GRAVITY:acceleration(not
constant velocity) toy car on ramp: not const. veloc. book- sitting
still on table: CONSTANT VELOCITY HOCKEY PUCK: CONSTANT VELOCITY IF
THERE IS NO FRICTION NASCAR PACE CAR: CONST. VELOC. UNLESS

- Standard: ________ of Objects is an introduction to the topic,
which will be further developed in Standard: Forces and
Motion._____indicates how fast something happens or how much
something changes in a given period of time (elapsed _____)._______
is described by the rates of speed, ______, and ________.Speedis
the rate at which an object is moving, or the total ________
covered over a time interval. Given a specified_____ interval
(e.g., one hour), thedistancecovered is proportional to the speed.
If the amount of ____ is constant and speed increases, the distance
traveled will increase. If time is constant, distance covered is
proportional to rate. If time is constant and the rate increases,
distances traveled will increase.
- ________is the speed of an object in a ___________). The change
in speed can be either an increase or a decrease (negative
___________ or deceleration).
- Speed and distance are_________(a quantity that can be added,
subtracted, multiplied, and divided like an ordinary number).
Velocity and acceleration are considered________quantities, because
they take the direction of the motion into account in addition to
magnitude. They cannot simply be treated as an ordinary
number.___________(the true measure from the starting point to the
ending point rather than the actual distance traveled) is also
considered a vector quantity. For example, if a person walks around
a square city block and comes back to the starting point, the
distance is 4 blocks and the ______ is 0. The use of the terms
vector and scalar should be applied to distinguish between the
vector quantities of displacement, velocity, and acceleration and
the scalar quantities of distance and ______.
- Motion can be described by a change in ______ relative to a
_________. The motion of an object can be described by its speed
and the ________it is moving. The position and speed of an object
can be measured and graphed as a function of time.
- Motion can be classified as______________, ______________,
___________ or __________. One-dimensional motion is movement of an
object in a straight line. Two-dimensional motion is the movement
of a projectile with both horizontal and vertical
components.__________motionis movement of an object a given
distance around a single point.Rotationis the spinning of an object
when it turns about its internal axis.Revolutionis the _________of
an object as it turns (circles) around an external axis. For
example, the spinning of the Earth is ________(takes 24 hours),
while the Earth circling the Sun is _________(takes 365.25
days)._________motionis back-and-forth movement of an object, such
as a pendulum.
- ______ is a push or pull. ___________is the original force.
________force is the opposite and equal force. Gravitational force
is dependent upon an objects mass. Centripetal force combined with
___________causes objects to travel in a circular path.
- Common Misconceptions Students may think that
- speed and velocity are the same.
- speed and acceleration are the same.
- acceleration and velocity are the same.
- the location of an object can be described by stating only its
distance from a given point (ignoringdirection)
- the terms distance and displacement are synonymous and may be
used interchangeably.
- acceleration always means an object is speeding up.
- acceleration is always in a straight line.

- I saw the word proportional and didnt really see the point- so
I put a (?) by it.
- I should raise my hand and say What does proportional mean? or
Do I need to know anything about the word proportional?
- ALSO- I underlined a LOT of words that were repeated. I can
study those.

15. Key Concepts
16. Velocityis the speed of an object in a given
direction.Accelerationis the rate at which velocity changes (either
a change in speed or a change in direction). The change in speed
can be either an increase or a decrease (negative acceleration or
deceleration). Speed and distance arescalar(a quantity that can be
added, subtracted, multiplied, and divided like an ordinary
number). Velocity and acceleration are consideredvectorquantities,
because they take the direction of the motion into account in
addition to magnitude. They cannot simply be treated as an ordinary
number.Displacement(the true measure from the starting point to the
ending point rather than the actual distance traveled) is also
considered a vector quantity. 17. Key Concepts
18.
- Abbreviate as many words as you can.
- UNDERLINE any words or ideas that the teacher says out
loud.
- Ask another student to trade notes. What did they see that you
missed?
- READ your books or handouts. Are you sure you understand the
main ideas?
19. For example, if a person walks around a square city block
and comes back to the starting point, the distance is 4 blocks and
the displacement is 0. The use of the terms vector and scalar
should be applied to distinguish between the vector quantities of
displacement, velocity, and acceleration and the scalar quantities
of distance and speed.Motion can be described by a change in
position relative to a point of reference. The motion of an object
can be described by its speed and the direction it is moving. The
position and speed of an object can be measured and graphed as a
function of time. 20. Key Concepts

22. Motion can be classified as one-dimensional,
two-dimensional, circular, or periodic. One-dimensional motion is
movement of an object in a straight line. Two-dimensional motion is
the movement of a projectile with both horizontal and vertical
components.Circular motionis movement of an object a given distance
around a single point.Rotationis the spinning of an object when it
turns about its internal axis.Revolutionis the motion of an object
as it turns (circles) around an external axis. For example, the
spinning of the Earth is rotation (takes 24 hours), while the Earth
circling the Sun is revolution (takes 365.25 days).Periodic
motionis back-and-forth movement of an object, such as a pendulum.
23. Key Concepts
24. Force is a push or pull. Action force is the original force.
Reaction force is the opposite and equal force. Gravitational force
is dependent upon an objects mass. Centripetal force combined with
inertia causes objects to travel in a circular path. 25.
