Speed and Velocity (Chapter 1 Lesson 2)

Speed and Velocity (Chapter 1 Lesson 2)

Author: Jason Fritz
Description:

I can answer the following questions:
•What is speed?
•How can you use a distance-time graph to calculate average speed?
•What are ways velocity can change?
 

6.2.2.1.1

Measure and calculate the speed of an object that is traveling in a straight line.

6.2.2.1.2

For an object traveling in a straight line, graph the object’s position as a function of time, and its speed as a function of time. Explain how these graphs describe the object’s motion.


•Speed is a measure of the distance an object travels in a unit of time. You can describe an object’s constant speed, instantaneous speed, or average speed.
•A distance-time graph shows the speed of an object.
•Velocity includes both the speed and the direction of motion.

Acceleration

Acceleration (pg 27) is a measure of how much the velocity of an object changes in a unit of time.

• An object accelerates when its velocity changes as a result of increasing speed, decreasing speed, or a change in direction.

Example: You are riding your bike at a velocity of 5 m/s down your street. A dog starts to chase you so you start to peddle as fast as you can for the next 2 seconds. You now have a velocity of 9 m/s. What is your acceleration? 9 m/s – 5 m/s = 4m/s divided by the time (2s) = 2 m/s/s is your acceleration.

SCIENCE OF NFL FOOTBALL: KINEMATICS

In this segment, NBC's Lester Holt and former NFL running back Deuce McAllister explore kinematics on the playing field. NSF-funded scientists Tony Schmitz from the University of Florida and John Ziegert of Clemson University explain how the kinematic concepts of position, velocity and acceleration can be used to define how a running back moves.

NASA | FLEET For Unseeded Velocity Measurements In All Speed Regimes

With many advances in computational methods, researchers increasingly rely more on computers to design airplanes and space vehicles. But, a lot of uncertainty continues to exist in their codes. This research targets finding a way to reduce, if not eliminate, some of the uncertainty.
