The document discusses force and motion through examples and explanations of key concepts like Newton's laws. It explains Newton's first law of inertia through an example of a pencil sitting still on a table. It also demonstrates Newton's third law of equal and opposite reaction through an example of hitting a balloon, feeling a push back from the balloon. The document uses examples, diagrams, and questions to help teach students about important force and motion concepts.

7. Break Down Definitions
Example or
Word Definition

An object in motion will stay in
Newton’s First Law motion and an object at rest
(law of inertia) will stay at rest, unless another
force acts upon it
Newton’s Second An object acted upon by a
Law force will move in the direction
of the force
Newton’s Third Law Forces always occur in equal
and opposite pairs

on the first incline to the speed of the marble on the second
incline.

15. Newton
Spring Scale used to measure Newton
• Definition: Metric unit of force = force which, if
applied to an object having a mass of 1 kg, would
give that object an acceleration of 1 m per second
per second in a vacuum
• symbol, N
• named in honor of English physicist Sir Isaac
Newton

in order from greatest amount of friction to least
amount of friction.

surface and measure the amount of force (in
Newtons) and write it on your table. Was your
predictions correct? Explain.
• In your own words what is friction?

17. Friction
The reason object slow down and
eventually stop
• There are four main types of friction:
• Sliding friction: sliding a book on a desk
• Rolling friction: bicycle tires rolling
• Fluid friction (gases or liquid): gases or water
resistance
• Static friction: initial friction when moving an
object

18. Friction
• Definition:
Force that
opposes the
motion of an
object
• With a partner
discuss which
arrows show the
direction of
friction and why.

constant velocity,
unless acted upon
by an unbalanced These fruits will stay at rest
force. until acted upon by an
unbalanced force.

• Now blow on the pencil or touch it with your
finger… what did the pencil do?

•The force in the pencil example was _________
•The motion caused by the force was _________

33. Newton’s 1 law

object in motion will
stay in motion at
constant velocity, unless
acted upon by an
unbalanced force.

What is the motion
caused by the force?

34. Why study force/motion?
• Newton’s 1st law (inertia) is why we need seat

by a force will move
in the direction of the

For every
action, there
is an equal
and
opposite
reaction.
Exhaust is action; rocket
flying is the reaction

interact with each
other, they exert
