Let's say you go on a run and start to sweat because you are heating up. What kind of energy conversion is happening? * Potential to Kinetic Kinetic to Thermal Potential to Thermal Kinetic to Potential
If an automobile with a velocity of 4.0 m/s accelerates at a rate of 4.0 m/s2 for 2.5 s, what is the final velocity?
A one-pixel difference in video measurement can cause a minor change in position, a noticeable change in instantaneous velocity, and a significant change in instantaneous acceleration. Bearing this in mind, compare the average acceleration you calculated with the instantaneous accelerations (ay) listed in the data table. Do the values agree? Explain your reasoning.
What is inertia and what is it related to?
Distance vs Displacement As an object moves, its location undergoes change. There are two quantities that are used to describe the changing location. One quantity - distance accumulates the amount of total change of location over the course of a motion. Distance is the amount of ground that is covered. The second quantity - displacement - only concerns itself with the initial and final position of the object. Displacement is the overall change in position of the object from start to finish and does not concern itself with the accumulation of distance traveled during the path from start to finish. True or False: An object can be moving for 10 seconds and still have zero displacement. A. True B. False
