Explain the difference between distance and displacement Solve problems using the formulas: speed = distance Velocity = displacement time time Solve problems for average speed and average velocity Solve problems for Acceleration Describe production rate and solve problems using that formula. Solve for angular speed in revolutions per minute and radians per second. Analyze graphs of velocity and time, speed and time, and acceleration and time. Calculate the average velocity and average acceleration 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
