of this lab is to show how to calculate the average speed and acceleration in six different races. In order to find average speed you will need to use the formula s=d/t (s= speed‚ d=distance‚ t=time). On the other hand‚ for accelaration you will use the formula a= vf-vi/t (a=acceleration‚ vf=final velocity‚ vi= initial velocity‚ t=time). Average speed is how fast something is moving; the path distanced moved per time. Acceleration is the rate of which velocity is changing‚ the change may be

the position vector is a function of time. Velocity & Acceleration • Velocity is defined as the change in position over a change in time; thus the average velocity is and the instantaneous velocity is • For motion in one dimension the velocity is the slope of the position line plotted versus time. • The same logic is used in deriving the average and instantaneous acceleration resulting in: • Jerk is defined as the rate of change of acceleration: Example 1 • A body starts from rest at x=0. ax(t)=2t-4

object moving with a constant acceleration can certainly slowdown‚ But can an object ever come to a permanent halt if its acceleration truly remains constant? Explain. -An object can never come to a complete stop if its acceleration remains constant because even if the velocity reaches zero‚ it will just continue‚ probably in the opposite direction #2 An airliner reaches its take off speed of 334 m/s from rest in 35.2 s.
