hey guys welcome back then we were doing see you then blocks me what the difference in speed and velocity is then if you remember in what direction velocity and everything's going to kind of feel. First day of what changes when an object accelerates in order for acceleration to happen something as a child see what that is how do you calculate the acceleration of an object in a straight line extending graphing World in class celebration of what changes when an object accelerates Irwin laundry acceleration sorry velocity changes velocity and directions it's acceleration happens when velocity changes Angels We Have Heard acceleration must have you think of it can you think of a car speeding acceleration acceleration acceleration deceleration something change in velocity directions never changes but if you change direction then you are accelerating you're going down the street to go on this way and then all the princesses turned right cuz directions to Celebration can be speeding up slowing down changing direct and your definition of acceleration is get rid of all this acceleration is the rate at which velocity changes over time and I will definitely need to write definition anytime you have acceleration due to a change in velocity right acceleration can be a change in an increase in Barrel motorcycle she goes around and around and around and routing on a string in your swinging it around the ball is continuously changing directions 360 degrees there you go and then a person ride a ferris wheel anything's going in a circle is accelerating Non-Stop centripetal acceleration how do you calculate acceleration of an object well you have to know the velocity right because it's the change in velocity equals the average acceleration over edible can be calculated by dividing the change by the time the right that equation. average acceleration final velocity make sure you realize that this is final velocity first and then initial velocity flat this could also be 2 - 1 of your time alright shut up all right into the whole thing went haywire here is your equation acceleration VF final velocity initial velocity means change in status of your change in velocity change in velocity minus the tire change rhetoric we already said this right here celebration is the rate at which velocity negative acceleration so I got to redo this I guess you need to write down at the SI unit for acceleration is flowerpot falls off of second-story window the flower pot starts from that something starts rest write that down starts from rest then you know your initial velocity equals 0 meters per second 0 meters per second equals 0 meters per second start from there we have that in class tomorrow so don't worry about this problem unless you want to try to figure it out tonight that's fine that is so
