Motion

• Speed


  how fast something is moving
• Speed


  measure of how quickly an object covers a distance
• Distance


  Total length of the path traveled
• Distance


  Actual length of the path taken
• Velocity


  vector quantity which refers to the rate at which an object changes its position
• Velocity


  requires speed and direction
• Acceleration


  rate at which an object velocity changes overtime
• Acceleration


  how quickly an object speeds up or slow down or changes direction
• Displacement


  refers to how far out of place an object is
• Displacement


  object's overall change in position
• Scalar Quantities


  measures magnitude only
• Magnitude


  size or extent of quantity or measurement
• Scalar Quantities


  measured with a number and unit only
• Vector Quantity


  measures both magnitude and direction
• Arrows


  used to represent vectors
• Arrow length


  shows the magnitude of the measurement
• Arrows way of pointing


  shows the direction of the vector
• Acceleration


  rate of change in velocity
• Average Acceleration


  provided to express that the acceleration rate may vary within the given time period
• Instantaneous Acceleration


  exact acceleration rate at a specific point of time
• Freebody Diagram


  shows all forces acting upon an object
• Freebody Diagram


  used to find the resultant force
• Force Arrows


  means by which we show forces acting on an object
• Resultant Force


  remaining measure of force
• Normal Force


  prevents an object from taking the place of another object
• Net force


  Resultant force
• Freebody Diagram


  shows if forces are balanced or not
• Freebody diagram


  shows the direction of the force or movement
