The motion of an object can be described by measurements of its position at different times. Velocity is a measure of the rate of change of position of an object. Acceleration is a measure of the rate of change of velocity of an object. This change in velocity may be a change in speed and/or direction. Motion is defined relative to the frame of reference from which it is observed. An object's sate of motion will remain constant unless unbalanced forces act upon the object. This is Newton's first law of motion.
- Calculate the average velocity of a moving object using data obtained from measurements of position of the object at two or more times.
- Determine and compare the average and instantaneous velocity of an object from data showing its position at given times.
- Collect, graph, and interpret data for position vs. time to describe the motion of an object and compare this motion to the motion of another object.
