What is the formula to calculate speed?Look in your journal. S=t÷d S=d÷t S=d•t S=t•d What is speed? Look in your journal. how far you go how much distance is covered over a period of time how fast you accelerate the change in the locationf of an object What is acceleration? the quickness of an object the location of an object change in an object's motion (position, direction, speed) caused by unbalanced forces. speed in a specific direction A runner races in the 100 meter dash. It takes her 10 seconds to finish. What is her average speed? 10 m/s 1000 m/s 100 km/s 10mph Total distance divided by total time is: constant speed sudden speed average speed fast speed What is the speed of an object that travels 60 meters in 4 seconds? No guessing. Solve and check the units. 0.067 m/s 15 m/s 240 km/h 15 mph What two measurements are necessary for calculating speed? Look in your journal. mass and time temperature and mass mass and distance distance and time A runner's times for each section of a 400-meter race are shown: Which best describes the runner's motion over the courseof the 400-meter race? Think carefully before you answer........ the runner's speed stayed the same the runner's speed increased The runner's speed decreased the runner's direction stayed the same Section Time 1st 100 m 11 seconds 2nd 100 m 13 seconds 3rd 100 m 14 seconds 4th 100 m 14.5 seconds An unusually fast zombie was chasing after Billy-Bob to eat him. What was the zombie's average speed after 6 seconds if he traveled 36 meters? 6 meters per second 6 seconds per meter 0.17 meters per second None of the above Soccer ball "A" goes 15 feet in 3 seconds and soccer ball "B" goes 12 feet in 2 seconds.Which ball moved he fastest? Soccer Ball "A" Soccer Ball "B" Their speeds are equal Which of the following is a unit of speed? km km/hr hr s Which of the following is a unit of time? km/hr km hr mi Find speed when distance is 142 km and the timeis 2 hours. If needed, use scrap paper to solve. 17 km/hr 90 km/hr 52 km/hr 71 km/hr Sally runs 100 meters in 20 seconds. What was her average speed? 5 s/m 5 m/s 5 km/s 5 m What is the method to solve for time? Look in your journal at the calculation triangle. time = speed ÷ distance time = distance ÷ speed time = speed x distance time = distance x speed |
