Science

• Motion- an object's change in position relative to a reference point
• Reference Point- A moving object can be used as a
• Scalar Quantities- Quantities that just have magnitude (strength) but NO direction ex. Spped, Mass, Volume, Density, Temperature, Distance
• Vector Quantities- Quantities that have both magnmagnitude (strength) and direction. Ex. Velocity, Force, Acceleration, Momentum, Electric Field, Displacement
• Distance- an important part of describing the motion of an object is to describe how far it has moved, which is
• Displacement- Refers to "how far" an object is from its starting point.
• C²=square root a² + b²- what is the formula on how to get the displacement.
• Acceleration - The rate of change in velocity is known as acceleration. If something is accelerating, it is doing one of the following:

  •speeding up

  • slowing down

  •changing directions
• Acceleration - The rate of change in velocity is known as __. If something is __, it is doing one if the following:

  •speeding up

  •speeding down

  •changing directions
• Scalar Quantities

  1. Speed
  2. Mass
  3. Volume
  4. Density
  5. Temperature
  6. Distance
• The SI unit for speed is meters per second (m/s).
• Vector Quantities

  1. Velocity
  2. Force
  3. Acceleration
