• According to Newtons third law of motion, do
  forces act alone or in pairs?
• Answer Forces act in pairs. For every Action
  force, there is an opposite and equal Reaction
  force!

• Newtons first law of motion, which states that
  an objects motion will stay the same unless it
  is acted upon by other forces is also called the
  Law of _____________.
• Answer Inertia

9
Sir Isaac Newsometon? 300

• If we know that the forces acting upon an object
  are balanced (Net Force Zero), what do we know
  about the objects motion?
• Answer The objects motion is staying the same.
  Its not changing. Its not accelerating.

10
Sir Isaac Newsometon? 400

• Using the formula F m a, what force (in Newtons
  N) is required to accelerate a 100 Kg object 2
  m/s2 (meters per second, per second)?
• Answer 200N

11
Sir Isaac Newsometon? 500

• What is needed to change the direction or speed
  of an objects motion? Or, what is needed to get
  the object to accelerate?
• Answer Unbalanced forces need to be acting upon
  it. Put another way, there needs to be a
  Non-Zero Net Force.

• If one van is loaded with 1 ton of lumber on its
  roof, and an identical one is loaded with 1 ton
  of lumber inside its cargo area, which one will
  be less stable going around a traffic circle and
  why?
• Answer The van loaded on its roof will be less
  stable because of its higher center of massit
  has a higher risk of rolling over.

  center of mass is _________.
• Answer Higher

  will take (a, b, c, or d)
• twice the distance to come to a stop
• more than twice the distance to come to a stop
• less than twice the distance to come to a stop
• the same distance to come to a stop.
• Answer (b) more than twice the distance to
  come to a stop
