• Energy is being degraded through friction.
The wheels are being heated up.

• Everywhere in the form of heat, and
friction, and motion.

• Only 10-20% of gasoline burned goes
toward moving the car forward.

All of the energy in the
universe is slowing
losing quality.

• At some point, many billions of years from
now,

• At some point, many billions of years from
now, the universe will be without any
usable energy.

 Newton’s 1st Law
 An object at rest tends to stay at rest and an
object in motion tends to stay in motion with
the same speed and in the same direction
unless acted upon by an unbalanced force.
 Called Law of Inertia

 Newton’s 1st Law
 An object at rest tends to stay at rest and an
object in motion tends to stay in motion with

 Inertia: Forces that resist to motion.

Inertia
– An object in motion tends to stay in motion unless
acted on upon by an unbalanced force.

on by a force.

• Activity! Try to pull the sheet of paper out
from under a stack of Dominoes without
having them fall.
– How does this activity demonstrate Newton’s
First Law of Motion?

• Activity! Try to pull the sheet of paper out
from under a stack of Dominoes without
having them fall.
– How does this activity demonstrate Newton’s
First Law of Motion?
• Answer: The Dominoes are at rest and will remain
at rest. The paper was yanked quickly (Motion)
and stayed in motion. The Dominoes did not fall
because of Inertia and Newton’s First Law of
Motion.

• Demonstration! Teacher will knock the bottom
Domino from the stack with their Samurai sword
(meter stick)
– How does this demonstration reflect Newton’s First
Law?

• Activity! Place a quarter or other object on a
playing card that’s on top of a container.
– Flick the card out quickly and see if the object
can land in the cup.

• Demonstration! Accelerating Car
– Design a vehicle that has a flat surface.
Place a passenger (weight), then quickly
accelerate.
• What happens? How does this relate to Newton’s
First and Third Law?

• Answer: The heavy weight wanted to stay
at rest and didn’t go into motion with the
car.

• Demonstration! Place a ball on a scooter board, move in
a straight line with attached rope, then turn the scooter
board to the side.
– What direction does the ball travel?
Petri-Dish taped
to Scooter

Answer: The ball rolled in a straight line
because an object in motion wants to stay
in motion and in the same direction.

• What is going to happen to Mr. Test Tube?

• Demonstration: Let’s create our own
version of Mr. Test Tube.

• Video! Crash Test with and without seatbelts.
– An object in motion will stay in motion

• Approximately 35,000 people die in motor
vehicle crashes each year.
– About 50 percent (17,000) of these people could
have been saved if they wore their safety belts.

• Wear a seatbelt! There’s room to live inside
of the car. Newton’s first law can be deadly if
you get in a car accident.

• Because of gravity, many objects thrown
through the air have a parabolic trajectory.

• Demonstration: Which will fall the fastest if
dropped at the same time?

• Demonstration: Now place the dollar on
top of the book and repeat?

• Objects with similar air resistance fall at
the same rate.
– Everything falls at the same rate of speed in a
vacuum.
– That rate is the gravitational constant.
• On earth (9.8 m/sec²)

• In space, away from the gravity of Earth,
you will keep going in one direction until
acted upon by another force.

Explain Newton’s first law with a few
sentences about this picture?

• Answer! The apple was in a state of rest
until acted upon by an outside force which
happened to be a very large ant.

• What do you feel when you go around a sharp
curve at high speeds?

• The word for this pulling force that you feel is
called “inertia.”

 Inertia: The property of matter by
which it retains its state of rest or its
velocity along a straight line.

• Inertia: The property of matter by
which it retains its state of rest or its
velocity along a straight line.
–So long as it’s not acted upon by an
external force.

• Lets hear it. Inertia as it applies to the
sport of curling.

• Activity! (Optional) Set-up a modified version
of curling by taping some colored paper to
your floor.
– Each table group elects one member to slide their
notebook across the floor and try to score for their table.
(Friction and Inertia)
– Pick an order, and your table group is allowed to knock
other notebooks out of the way.
– Whatever team is closest to the scoring area at the end
wins. Run it again in the opposite direction.

Inertia can pull a car off the road
or across the double line and into
on coming traffic.

• How does inertia apply to this racer?

• The driver must have the perfect lean
angle of the motorcycle so that the force of
gravity reaches equilibrium with the
centrifugal force attempting to stand the
bike back up.

– Driver must have an understanding where
their center of mass is.

• Center of Mass: Point in a body at which the
whole mass may be considered as
concentrated.

• Center of Mass: Point in a body at which the
whole mass may be considered as

– Usually associated with center of gravity. Similar
concepts on Earth.

• Activity: Use the Dominoes to recreate the
picture below.
– Try and get as far from the table as you can
before the center of gravity is off of the edge.
– Sketch your stack and draw a line where you
think the center of gravity / mass will be.

• Activity: Finding the Center of Mass

– Put your hands together on your desk to
make a fulcrum point.

– Place a meter stick on the fulcrum so it is
balanced.

– Add a weight to one end and try to find the
new center of mass.

that can be placed in an empty soda can and
still have lean on its side.

• Activity: Dueling Pendulums
– Lift one pendulum to the side and release in the
direction of the arrow. What happened?
– Does this activity break Newtons First Law of
motion that an object at rest tends to stay at rest.

• Activity: Dueling Pendulums
– Answer: No, the swinging pendulums energy is
transferred to the still pendulum.
– Remember, Energy cannot be created or
destroyed but transferred between systems and
surroundings.
