Hi. Good video. For area of Trapezoid should the equation rather be Area = B (1/2 H1 + H2) Where: H1 is height of triangle and H2 is height of quadrilateral.
Sir how the displacement is 275m The object started at origin and after some time it again reached at the same position so velocity turned 0 and the displacement also turned 0 So I didn't understood how the displacement is 275 m??
You're reading the graph as if its a pos-time graph. It is not. Its a vel-time graph. It does not indicate what position it started and finished with. It indicates what velocity it started and finished with.
@@PhysicsclassroomVideos So sir when velocity is 0 Means the object is at rest... Or The object started and reached at the same position .. So when velocity is 0 ??
Excellent
Sir what is wrong with the note of this lessons ? I couldn't download it
Looks like we forgot something. We should be able to get that up by the end of he day. Thanks for letting us know.
The page at www.physicsclassroom.com/Physics-Video-Tutorial/Kinematics/Velocity-Time-Graphs-Calculating-Displacement/Lecture-Notes is now fixed.
helloo How did the average velocity in 2:29 become 2 what is the formula thank you
Average the initial and final velocities ==> (0 + 4)÷2
@@PhysicsclassroomVideos thank youu
but why is it to be divided? does that mean finding velocities should always be divided by 2?
Hi. Good video. For area of Trapezoid should the equation rather be
Area = B (1/2 H1 + H2)
Where: H1 is height of triangle and H2 is height of quadrilateral.
A = B * (1/2)*(H1 + H2)
Which is equivalent to the equation given in the video. You need to average the 2 heights and multiply by the base.

@@jayantideshpande8459 At rest. Doesn't mean a thing about position.
@@PhysicsclassroomVideos when a object which has a motion
Suddenly comes to stop...
Then the velocity is 0 ??
This is my doubt...
