![]() Infinitesimally-small displacement divided by an infinitesimally-small But we're gonna run into a problem here because if you wanna find a perfect value for the instantaneous velocity, you'd have to take an Smaller displacement over that even shorter time interval. The instantaneous velocity, we could choose an even This would give you a better value for the instantaneous velocity but Point where you're trying to find the instantaneous velocity. In that case, you'd wannaįind a smaller displacement over a shorter time interval that's centered at that The instantaneous velocity at a particular point in Still just gonna be four meters per second to the right or, if you like, positiveįour meters per second. Up or slowing down that took place during this path, your average velocity's Speeding up and slowing down and changing your speed at every moment. Say you jogged 60 meters in a time of 15 seconds. The instantaneous velocities at particular points on your trip. Meters away from school and it took you a total ofĢ00 seconds to get there, your average velocity wouldīe five meters per second, which doesn't necessarily equal Note that this is differentįrom the average velocity. Velocity of this person at that particular moment in time. Per second to the right was the instantaneously And if you include theĭirection with that speed, you get the instantaneous velocity. ![]() Is the speed of an object at a particular moment in time. ![]() When you get a littleĬloser to home, you say: "No, Captain Antares wouldn't give up "and I'm not giving upĮither", and you start running at eight meters per secondĪnd you make it home just in time for the opening music. Since the last time you ran, so you have to slow down a little bit to two meters per second. You're pretty motivated to get home, so say you start runningĪt six meters per second. Wars marathon on tonight, so you'd do what every You were walking home when you remembered that there was a Galaxy
