Best ResponseYou've already chosen the best response.1xplain tangential acceleration and radial acceleration .how to find net acceleration?when are the cases when they become 0 alternatively?

Best ResponseYou've already chosen the best response.3dw:1329408300806:dwthe terms are not quite what I'm used to, but radial acceleration is a result of the change in direction of the object:\[a=\frac{v^2}r\]it is because the motion vector changes that we get this acceleration (change in direction always means acceleration is happening) so if the object is moving in a straight line the radial acceleration (I call it centripetal acceleration) is zero

Best ResponseYou've already chosen the best response.3this illustrate that the change in direction causes an acceleration because the velocity vector changesdw:1329408593274:dwAs for tangential acceleration that is a result of the object speeding up or slowing down linearly. if, say, we have an object moving in a circular path we have\[a=\alpha r\]where alpha is the angular acceleration:\[\alpha=\frac{d\omega}{dt}\]So if the angular velocity is changing, the object is experiencing a tangential acceleration.

Best ResponseYou've already chosen the best response.1so radiall acc does not contribute to change in angular velocity?

Best ResponseYou've already chosen the best response.1doubt 2:when an apple falls towards earth the earth moves up to meet the apple .is this true xplain?

TuringTest
 4 years ago
Best ResponseYou've already chosen the best response.3no radial acceleration happens just by virtue of the object turning, tangential means the object is actually speeding up along the direction of motion (circle, line, whatever) Last question: Yes this is true, because the all forces come in actionreaction pairs. Because the earth exerts a force (gravity) on the apple, the apple exerts a gravity force on the earth. The magnitudes of those forces are the same, therefor the earth doesn't move much, but it must theoretically move some.

Best ResponseYou've already chosen the best response.1hey why does earth move less?

TuringTest
 4 years ago
Best ResponseYou've already chosen the best response.3because it is more massive, and\[F=ma\]m of the apple is small, and m of the earth is large, so the same force on the apple and earth will cause a much greater acceleration on the smaller mass (the apple) than the earth

Best ResponseYou've already chosen the best response.3if v1=v2 from one point to the next we have 0 change in tangential velocity, which is tangential acceleration of 0dw:1329409969038:dw

TuringTest

Best ResponseYou've already chosen the best response.3well area times velocity is a constant for an incompressible fluid like water, so when the tube narrows the speed of the water increases. I'm pretty sure they multiply to unit volume passing though the area in question

Best ResponseYou've already chosen the best response.1Speed= distance/ time Area*distance/time Volume/time

TuringTest

Best ResponseYou've already chosen the best response.3...or just looking at units\[v\times A=\frac ms\cdot m^2=\frac{m^3}{s}\]which at least suggests it's volume over time
