Motion in a straight line Flashcards
what is displacement
is the distance between two points in a specified direction
whats speed
is the rate at which distance changes with time
whats velocity
is the rate of change of displacement with time
whats the triangle for speed
//////////distance /////////
////average speed / time
whats the triangle for velocity
/////////displacement //////
//average velocity //// time//
how do you find the average speed
initial speed + finial speed
divide by 2
whats the rate of change of speed triangle
/////////////final speed - initial speed /////////////
/////rate of change of speed / time taken////////////
what does vector quantities have
magnitude and direction
what does scalar quantities have
magnitude
what does velocity show us
what direction the object is going
whats the acceleration triangle
/final velocity - initial speed //
////acceleration/////////// time ///////
whats the triangle for average velocity
// u+v
ave v // t
how do you find the average speed
initial speed + finial speed
divide by 2
whats acceleration
is the rate of change in velocity with time
