Cause and Effect


Students know:
  • A body is in motion if its position changes with respect to its surroundings.
  • A particle moving in a straight line undergoes one dimensional motion.
  • A particle moving along a curved path in a plane has two dimensional motion.


Students are able to:
  • Create graphs from sets of data points.
  • Identify distance and displacement as a scalar/ vector pair.
  • Identify speed and velocity as a scalar/ vector pair.
  • Describe motion mathematically in terms of an object's change of position, distance traveled, and displacement.
  • Apply concepts of average speed and average velocity to solve conceptual and quantitative problems.
  • Explain velocity as a relationship between displacement and time. (Δd=vΔt)
  • Explain acceleration as a relationship between velocity and time. (a=Δv/Δt)
  • Use graphical analysis to understand conceptual trends in displacement, velocity, acceleration, and time.
  • Use graphical analysis to solve for displacement, velocity, acceleration, and time.
  • Calculate velocity and acceleration from displacement vs. time graphs.


Students understand that:
  • Motion graphs (displacement vs. time, velocity vs. time, and acceleration vs. time) for one- and two- dimensional motion may be used to derive (conceptual and mathematical) relationships of motion.
