  • Explain why a car turning a corner at a constant speed of 20 m/s is not traveling at a constant velocity.
    Because the direction of the car is changing, velocity is not constant (vector).

  • What does a horizontal line on a distance vs time graph represent?
    motionless
  •  10
  • What does a diagonal, straight line represent on a distance vs time graph?
    constant speed
  •  10
  • What does a curved line represent on a distance vs time graph?
    non-constant speed (acceleration)
  •  10
  • What does a horizontal line above the x axis represent on a speed vs time graph represent?
    constant speed
  •  10
  • What does a horizontal line on the x axis on a speed vs time graph represent?
    motionless
  •  10
  • What does a straight, diagonal line represent on a speed vs time graph?
    constant acceleration
  •  10
  • What does negative slope represent on a speed vs time graph?
    slowing down
  •  10
  • What does negative slope represent on a distance vs time graph?
    going back to start
  •  10
  • How do you calculate distance?
    Add up all of the lengths to get a total distance.
  •  10
  • What does "delta v" represent?
    change in velocity (final velocity minus initial velocity)
  •  15
  • Explain why rate and speed are considered the same thing.
    Both divide distance by time.
  •  10
  • Explain the motion of the object in the graph.
    slow constant speed away from start, stopped, slow constant speed away from start, fast constant speed home
  •  25
  • Calculate the speed of the object during the third section of movement
    S=? D=30m T=3s S=D/T S=30m/3s S=10m/s
  •  25
  • Describe the motion of the object using the graph.
    accelerating quickly, constant speed, slow acceleration, slow deceleration
  •  25
  • Describe the acceleration of the object using each section of the graph
    positive, zero, positive, negative
