Questions and Answers

What is the correct definition of displacement?

  • The average speed of a particle over a period of time.
  • The instantaneous speed at a specific moment.
  • The total distance traveled by a particle.
  • The change in position of a particle, represented as a vector. (correct)

    • Displacement is the same as the total distance traveled by an object.

    False

    What is the formula for average speed?

    • Topics: Position, Velocity, Speed, Instantaneous Velocity, Speed, Acceleration, One-dimensional motion with constant acceleration, Vector analysis

    Chapter 2.1 Displacement, Velocity, and Speed

    • Displacement: Change in a particle's position; a vector quantity
    • ∆x = xf - xi
      • if xf > xi, ∆x is positive (+)
      • if xf < xi, ∆x is negative (-)
    • Displacement is not equal to distance traveled
    • Distance traveled = AC + CB
    • Displacement = AB

    Chapter 2.2 Instantaneous Velocity and Speed

    • Instantaneous velocity: The limit of the average velocity as the time interval approaches zero.
    • vx = lim∆t→0 ∆x / ∆t = dx/dt
    • The slope of the tangent line on a position-time graph is equal to instantaneous velocity.
    • Instantaneous velocity can be positive, negative, or zero.
    • Instantaneous speed: Magnitude of the instantaneous velocity

    Chapter 2.3 Acceleration

    • Acceleration: Rate of change of velocity.
    • ax = ∆vx/∆t = dvx/dt.
