Average velocity and speed review (article) Khan Academy

WebFinal velocity times final velocity. And so we can just solve for final velocity here. So we know our acceleration is negative 9.8 meters per second squared. So let me write this over here. So this is negative 9.8. So we have 2 times negative 9.8-- let me just multiply that out. So that's negative 19.6 meters per second squared. WebIf an object changes direction in its journey, then the average speed will be greater than the magnitude of the average velocity. Speed is a scalar, and average velocity is a vector. Average velocity indicates direction and can be represented as a negative number when the displacement is in the negative direction.

Determine the object’s acceleration by dividing the object’s mass by force and multiply the answer by the time it took for it to accelerate. For example, if the object weighs 30 kg and has a force of 15 N applied to it, then the acceleration would be 4 m/s. flights nclWebA value of velocity can be negative as a negative value would mean the object is travelling at the opposite direction than the intended one. For example: If a banana was travelling at 5 m/s to the right you would say it has a velocity of 5 m/s. If its velocity were -5 m/s it would mean that the banana was travelling 5 m/s to the left. flights ncl to bkk
