Speed and Velocity

We head to the Porsche Experience Center Atlanta track to learn about the difference between speed and velocity. Different types of velocity are explored and we investigate how to find information from a position versus time graph.

Unit 2 Segment B: Speed and Velocity We head to the Porsche test track to learn about the difference between speed and velocity. Different types of velocity are explored, and we investigate how to find information from a position versus time graph.

## Vocabulary

average speed - an object’s total distance traveled divided by the time elapsed. The SI unit is meters/second (m/s).

average velocity - an object’s displacement divided by time elapsed. The SI unit is meters/second (m/s).

constant velocity - velocity that remains unchanged.

displacement - an object’s overall change in position; the SI unit is the meter (m).

distance - is a measure of how far an object has traveled; the SI unit is the meter (m).

instantaneous velocity - the velocity of an object at a specific point in time.

## Georgia Standards of Excellence

SP1Obtain, evaluate, and communicate information about the relationship between distance, displacement, speed, velocity, and acceleration as functions of time.

SP1.aPlan and carry out an investigation of one-dimensional motion to calculate average and instantaneous speed and velocity. • Analyze one-dimensional problems involving changes of direction, using algebraic signs to represent vector direction. • Apply one-dimensional kinematic equations to situations with no acceleration, and positive, or negative constant acceleration.

SP1.bAnalyze and interpret data using created or obtained motion graphs to illustrate the relationships among position, velocity, and acceleration, as functions of time.

SP1.cAsk questions to compare and contrast scalar and vector quantities.

SPS8Obtain, evaluate, and communicate information to explain the relationships among force, mass, and motion.

SPS8.aPlan and carry out an investigation and analyze the motion of an object using mathematical and graphical models. (Clarification statement: Mathematical and graphical models could include distance, displacement, speed, velocity, time, and acceleration.)
