2. Graph your velocity for different walking speeds and directions, and sketch your graphs on the axes. (Just draw smooth patterns; leave out smaller bumps that are mostly due to your steps.) a. Make a velocity graph by walking away from the detector slowly and steadily. Try again until you get a graph you're satisfied with.

Speed can be expressed as kilometers per hour (km/hr), meters per second (m/s), and so on. In most cases, objects don’t travel at a constant speed. Therefore, the average speed is used to describe the motion. s = speed, t = time, and d = distance. Acceleration is the rate at which an object’s speed changes.

Nov 27, 2012 · Velocity includes speed AND something else. What do you think makes velocity different from speed? Why do the two vehicles pictured above have different velocities? The following vehicle has the cruise control set to 20 km/hr. The speed is remaining constant, but the velocity is not constant—it is changing. Explain why.

Determining air velocity is a useful part of testing. It is calculated as follows: V = 1096.7* √¯H/d . ... Mean Gas speed from piston speed (above) and "area/cross section quotient": ... because depending on the character of the motor's use you will have different aims. Starting from: ( S/ 360 ) x RPM x ( B area / P area) = ft/sec or ...

Velocity is similar to speed but also includes direction. For example, if a car is traveling south at 55 mph then we can say the velocity is 55 mph south. Objectives . Investigate the concepts of position, direction, speed, and velocity. Measure and graph distance versus time for an object moving at a constant speed. Interpret this relationship.

To describe speed you have to know two things: 1) the . distance. traveled, and 2) the . time. it took to travel that distance. To calculate speed, all you have to do is divide distance by time. Velocity. is just speed in a particular direction. For example, if in 3 hours you ran 6 kilometers west, your velocity was 6 km/3 hours = 2 km/hour west.

7. Now look at your graphs of position and velocity versus time. How can you tell from the velocity data when the walker’s speed was zero? 8. How can you tell from the velocity data which direction the walker was walking? 9. What is the difference between a velocity of 0.5 meters per second (m/s) and a velocity of –0.5 meters per second (m ...

Speed and Velocity Problems. What is the average speed of a cheetah that sprints 100 m in 4 s? How about if it sprints 50 m in 2 s? If a car moves with an average speed of 60 km/hr for an hour, it will travel a distance of 60 km.

A. Speed is the measure of the rate of change in position B. Velocity describes both the speed and direction of an object - So Speed is directly related to velocity but they are not the same thing
