Unit 2 Kinematics Again
This plane is moving through the air in a certain direction at a certain speed, but it will not remain at the same speed all the time. For example, the instantaneous velocity at lift off and landing will vary. So an average velocity can be calculated as the change in displacement over the change in time. In regards to these three variables, if at least of the two variables are known, the third can be calculated.
D=VT
That is how pilots predict the length of their journey. All they have to do is divide the distance of their destination by their average velocity to determine how long it will take to get there.
cool picture! we can do this also with cars. to see how long it will take us
ReplyDeletethis picture is super epic with the dark clouds and the the light blurriness of the plane. plus this is fresh because we've all been thinking of cars when there are planes, boats, birds and bugs (like Monarch Butterflies).
ReplyDeleteYa we can do this with all sorts of vehicles.
ReplyDeleteThanks, its really just the poor quality of my camera but I thought it looked like a shark:)
So planes don't have a constant velocity. Sounds simple enough...although the pilots wouldn't necessarily know the average velocity beforehand right? Possibly they take the average velocity of the same flight the day before? nice example :)
ReplyDeleteYa they probably base estimates off of previous routes taken.

ReplyDeletehaha, yup exactly. it gives all vehicles a sense of predictability.
