#### Transcript Force and Motion

```The student knows that
there is a relationship
between force, motion,
and energy.
A) Demonstrate and calculate how unbalanced
forces change the speed or direction of an
object's motion.
B) Differentiate between speed, velocity and
acceleration.
C) Investigate and describe applications of
Newton’s law of inertia, law of force and
acceleration, and law of action-reaction such as
in vehicle restraints, sports activities,
amusement park rides, Earth’s tectonic
activities, and rocket launches.

I feel the need…
The need for speed!
-the distance traveled by an
object in a given amount
of time.
speed = distance
time
-units = meters/second
or
m/s
Speed = distance / time
s = d/t
Units: unit of distance (meters,
inches, miles)
Unit of time (seconds, minutes,
hours)
d
S
t
-speed of an object and its
direction of motion
Ex. 40 m/s to the North
Graph the data
What is happening to
the speed?
 What would the line
look like if there was no
motion?
 Write down the data

stationary object.

-rate in change of velocity
Acceleration measures how an object
changes velocity by either moving faster,
slower, or changing direction.

There is something about a
line graph that makes
people think they're
looking at the path of an
object. A common
beginner's mistake is to
look at the graph to the
right and think that the the
v = 9.0 m/s line
corresponds to an object
that is "higher" than the
other objects. Don't think
like this. It's wrong.
In this case, higher means
faster.

law of inertia, law of force and acceleration, and
law of action-reaction such as in vehicle restraints,
sports activities, amusement park rides, Earth’s
tectonic activities, and rocket launches.
Write down Newton’s 3 Laws of Motion.
Write down an example of each Law.
I.
II.
III.
An object at rest or in motion will stay at rest
or in motion unless acted upon by an
unbalanced force.
Force = mass times acceleration
For every action there is an equal and
opposite reaction.
An object at rest will stay at rest unless acted
upon by an unbalanced force.
An object in motion will stay in motion
unless acted upon by an unbalanced force.
Name the force that opposes motion and
creates heat.
2. The tendency of an object to stay at rest or to
stay in motion.
Bonus: Write Newton’s First Law of Motion
1.
Force = mass x
acceleration
For every action there is
an equal and opposite
reaction.
-any force that resists motion
-creates heat
Potential Energy-the energy of
position.
-stored energy an object has
because of its position or
shape.
Kinetic Energy-the energy of
motion.
-energy an object or particle
has because it is moving.
Identify Newton’s 3 Laws of Motion.
1. Force = mass x acceleration
2. For every action there is an equal and opposite
reaction.
3. An object at rest or in motion will stay at rest or
in motion unless acted upon by an outside,
unbalanced force.

depicted by the picture.
1.

3. Name the force that resists motion.
4. The distance traveled by an object in a given
amount of time.
5. Identify the type of force (balanced or unbalanced).
Bonus: The speed of an object and its
direction of motion.
5. If the forces acting upon an object are balanced,
then the object
a. must not be moving.
b. must be moving with a constant velocity.
c. must not be accelerating.
d. none of these
Bonus: Find the net force on an object if the
following forces are working upon it:
150 N to the right
230 N to the left
Several of Luke's friends were watching the motion of the
falling cat. Being "physics types", they began discussing
the motion and made the following comments. Indicate
whether each of the comments is correct or incorrect?
2. Once the cat hits the water, the forces are balanced and
the cat will stop.
3. Upon hitting the water, the cat will accelerate upwards
because the water applies an upward force.
4. Upon hitting the water, the cat will bounce upwards due
to the upward force.

a=9 m/s2
5. F=75 N
m=25 kg
a =?
Bonus: What is the rate of change of velocity?
If the car has a force of 30 N, how much
force does the man and his eyelids have
to produce to pull the car?
1. Force = ?
Mass = 15 kg
Acceleration = 5 m/s2
2. Force = 48 N
Mass = 4 kg
Acceleration = ?
3. Force = 86 N
Mass = ?
Acceleration = 43 m/s2
4. Force = ?
Mass = 25 kg
Acceleration = 10 m/s2
5. Force = 72 N
Mass = 9 kg
Acceleration = ?
Bonus: Force = 123,456 N
Mass = ?
Acceleration = 10 m/s2
-done when an applied force
causes an object to move in the
direction of the force.
-pushing or pulling
Work = Force (N) x Distance (m)
W=Fxd
Units: N·m = Joules (J)

Ex. Mr. McDonald’s car has run
out of gas 100 m from a gas
station. If Mr. McDonald
produces 25 N of force how
much work will Mr. McDonald
do pushing his car to the gas
station?
1.Force = 450 N
Mass = ?
Acceleration = 10 m/s2
2. Speed = 540 m/s
Distance = 12 m
Time = ?
3. Work = 225 J
Force = 5 N
Distance = ?
4. Force = 135 N
Mass = 3 kg
Acceleration = ?
5. Speed = 405 m/s
Distance = ?
Time = 9 s
Bonus:
Work = ?
Force = 3 N
Distance = 15 m

being accelerated 5 m/s2?
Mr. McDonald’s car has run out of gas 250 m from
a gas station. If Mr. McDonald produces 50 N of
force how much work will Mr. McDonald do
pushing his car to the gas station?
