Motion

• Motion - continuous change in position with respect to a reference point for a particular time travel
• Reference Point - starting point or origin for measuring motion
• Distance - total length of the entire path
• Scalar Quantity - single number indicating size magnitude or dimension. Specified by magnitude alone
• Displacement - shortest distance
• Vector Quantity - specified by a magnitude and direction.
• Pyramid of formula

  A) Distance

  B) Time

  C) Speed

  
• What formula?

  A) Velocity

  
• What formula?

  A) displacement

  
• Velocity - How fast an object is moving and to which direction.
• Instantaneous - speed change

  Constant Speed - Does not change it’s speed
• Velocity - How fast an object is moving and to which direction.
• Acceleration - refers to the  rate of change in speed or velocity of an object. How quick an object speeds up or slows down
• Positive Acceleration - increases

  Deceleration - Decrease
• Formulas

  A) Acceleration

  B) Initial Velocity

  C) Final Velocity

  D) Time

  E) Distance

• Diagrams - visual representations that explain an idea or info using symbols and pictures

  • Slope - in a graph gives  us an idea about the movement of an object.
  • Motion Graphs-Visual Representation that uses lines to show how to or more sets of measurements are related to each other.
• Ticker timer - used to study motion of an object for a short period of time. Steel strip will vibrate, making 50 dots a second.
• Ticker timer speed calculation

  A) time

  B) speed
