This red car is rolling swiftly down the hill. Since this car has values that can be measured with magnitude and direction it is called a vector. Some examples of vector measurements are displacement, or distance traveled in a certain direction, and velocity. The velocity, or speed in a direction, of the car will naturally accelerate as it goes down the hill. Acceleration is a change is speed or direction. When it reaches the bottom of the hill the acceleration will be zero because velocity will be constant, or unchanging. That is assuming the driver maintains a stable speed limit and doesn't hit the gas or slam on the breaks. The slope of a constant acceleration is zero and on a graph it would be represented by a flat horizontal line.
Using cars as a way to test acceleration was a good idea. The way that they can change their acceleration or keep the same velocity is good for showing a velocity over time graph.
ReplyDeleteYeah thank you, i thought it was a good simple example: D
ReplyDeletei love how you drew something instead of taking a picture
ReplyDeletethanks, although my skills do not nearly compare to yours. xp
ReplyDeletei had fun, and it was easy
