Under what condition(s) is the magnitude of average velocity of an object equal to its average speed? Solution Since average speed is the total distance travelled in a time frame and velocity is the total displacement in the time
Speed, Distance, Time Worksheet. Use * m/s, km/h, or mph. Calculate Speed R̅= P 1. A car travels a distance of 540km in 6 hours. Calculate the speed of the car. 2. John is a runner. He runs the 100m sprint in 20.0 s. Calculate the John’s speed. 3. Lauren walks 400 m in 125 s . Calculate Lauren’s average speed. 4.
The rate of change of velocity. If the distance versus time graph of an object is a horizontal line, the object is. Moving with constant speed. Moving with constant acceleration. At rest. Moving with zero acceleration.
Lakhmir Singh Solutions for Class 9 Physics Chapter 1- Motion Answer: A body is said to have a uniform velocity when it covers equal distances in equal intervals of time in a particular distance. Q12. Under which condition is the magnitude of average velocity equal to average speed? Answer:
