  • Who will hit a baseball harder: an adult or a child? Will it go farther? Which Law of Motion tells us that more force creates more acceleration?
    Newton's 2nd Law of Motion states that Force = Mass x Acceleration (more force creates more acceleration)
  • The rate at which velocity changes - if we speed up, is that positive or negative acceleration?
    Speeding up in POSITIVE acceleration
  • The force when 2 surfaces rub against each other. A. Friction. B. Gravity.
    A. Friction
  • If you see a ball bounce, what Law of Motion are you witnessing? 1st, 2nd, or 3rd
    Newton's 3rd Law of Motion - for every action there is an equal but opposite reaction
  • The distance an object travels in one unit of time. A. Motion. B. Speed. C. Velocity
    B. Speed.
  • The rate at which velocity changes - if we slow down, is that positive or negative acceleration?
    Slowing down is NEGATIVE acceleration
  • If you see someone push in their chair, what Law of Motion are you witnessing? 1st, 2nd or 3rd
    Newton's 1st Law of Motion - an object at rest remains at rest unless acted upon by an unbalanced force.
  • If I rub my hands together, what force am I using? Gravity, Velocity, or Friction?
    Friction! It's when 2 surfaces rub against each other.
  • Speed in a specific direction. A. Motion. B. Speed. C. Velocity
    C. Velocity
  • True or False: Velocity is speed in a specific direction.
    True! That is the definition of Velocity.
  • Force = mass x acceleration; Objects with a large mass require more force
    Newton's 2nd Law of Motion - think of a semi trying to stop quickly vs a little car
  • The state in which one object's distance from another is changing. A. Motion. B. Speed. C. Velocity
    A. Motion.
  • The force that pulls objects toward Earth. A. Friction. B. Gravity.
    B. Gravity.
  • For every action, there is an equal but opposite reaction
    Newton's 3rd Law of Motion - think of an echo
  • True or False: A force is a push or pull on an object unit Newtow (N)
    True. That is the definition of force.
  • An object at rest remains at rest unless acted upon by an unbalanced force. Which Law of Motion?
    Newton's 1st Law of Motion - think of Mr. Wolfe moving a tissue
  • Finish this sentence: 65 miles per hour is measuring a car's _________.
    Speed - miles per hour describes the distance (miles) an object (the car) travels in one unit of time (hour)
