Daily TAKS Connection: Newton

Daily TAKS ConnectionNewtons Laws Motion,
Work and Power

• IPC(4) The student knows concepts of force and
  motion evident in everyday life. The student is
  expected to. The student is expected to
• (A) calculate speed, momentum, acceleration,
  work, and power in systems such as in the human
  body, moving toys, and machines.
• (B) investigate and describe applications of
  Newtons Laws such as in vehicle restraints,
  sports activities, geological processes, and
  satellite orbits.

• Construct a three flap foldable
• Materials
• Foldable handout
• Scissors
• Pen
• Colored pencils/crayons

• Instructions
• Fold bottom paper along fold line at bottom edge
• Color flap Newtons Laws
• Hotdog fold along center fold line
• Cut along the dotted lines from edge to peak
• Tuck the flaps into the bottom flap
• Color flap labels

Law of Inertia

• Record the following notes in your foldable under
  the inertia tab
• an object at rest will remain at rest unless
  acted on by an outside force
• an object in uniform straight line motion will
  stay in that uniform straight line motion unless
  acted on by an outside force

Question 1

• Safety restraints in cars help prevent passenger
  injuries that would otherwise occur as a result
  of passengers remaining in motion during a cars
  abrupt stop. Which of these laws predicts that
  an unrestrained moving body will continue to
  move?
• A. Law of inertia
• B. Law of reflection
• C. Law of universal gravitation
• D. Law of conservation of momentum

5
Question 2

• A wet bar of soap slides 1 meter across a wet
• tile floor without appearing to slow down.
• Which of these statements explains why the
• bar of soap fails to slow down?
•  A. A constant force on an object produces a
• constant positive acceleration.
• B. An object in motion tends to remain in
• motion in the absence of an external force.
• C. A moving object having constant velocity
• contains kinetic energy.
• D. An objects weight is proportional to its
• mass.

6
F ma

• Record the following notes in your foldable under
  the F ma tab
• Using your formula chart, write out Newtons 2nd
  law
• Rearrange the equation to solve for both mass and
  acceleration
• Record the gravitational force from your formula
  chart
• All objects are affected by gravity
• The effect of gravity increases the closer two
  objects are to one another
• All objects fall at the same rate (gravity)
  however, air resistance (an opposing force) can
  slow things down

Question 3

• Which of these would cause the gravitational
• force between Earth and the sun to increase?
• A. An increase in the length of a day on
• Earth
• B. A decrease in the distance between Earth
• and the sun
• C. An increase in the number of planets
• orbiting the sun
• D. An increase in the masses of Earth and
• the sun

Question 4

• How many newtons of force does a 75.0 kg student
  exert on their chair because of gravity?
• (Solve problem in your foldable under Fma tab)

9
Question 5

• After shooting a cannonball, a cannon recoils
  with a much lower velocity than the cannonball.
  This is primarily because, compared to the
  cannonball, the cannon has a -
• A. much greater mass
• C. greater kinetic energy
• B. smaller amount of momentum
• D. smaller force applied to it

10
Question 6

• A leaf from an apple tree falls to the ground
  more slowly than an apple falls. As an
  explanation of this observation, the ancient
  Greeks theory of natural place has been replaced
  by a more recent theory involving gravitational
  force and
• A. atomic weight
• B. inertial mass
• C. air resistance
• D. kinetic energy

11
Action/Reaction

• Record the following notes in your foldable under
  the action/reaction forces tab
• For every action there is an equal and opposite
  reaction
• action and reaction in Newton's third law are
  forces
• An action-reaction pair includes only two objects

12
Question 7

• Which of the these is the best description of the
  action-reaction force pair when the space shuttle
  lifts off from the launchpad?
• A. The ground pushes the rocket up while exhaust
  gases push down on the ground.
• B. Exhaust gases push down on air while the air
  pushes up on the rocket.
• C. The rocket pushes exhaust gases down while the
  exhaust gases push the rocket up.
• D. Gravity pulls the exhaust gases down while
  friction pushes up against the atmosphere.
