on the p t graph the slope of the line is the velocity....therefore if the line is becoming less steep then it is slowing down..

[bhswarthout]

Since the slope of the v vs t graph is the acceleration, if the graph has a constant slope (is a straight line) then the acceleration must be constant.

The pleasure it all mine!

[bhswarthout]

If there is a force applied in the direction of motion or in the opposite direction of motion (friction) then work is done by that force.  But if the velocity is constant then the net work done on the object is zero.

Hi Joules,

Glad you find the videos helpful. Berlin is great, you would love it.

From this graph you can get two things (1) the position of the object at a specific time and (2) from the slope of the line/curve you can get the velocity of the object. The slope of the position vs time graph is the velocity of the object.

how do you know when an object is slowing down on a P vs T graph?

am i the only one impressed by how neat he is with that computer pen!...DAMN
