Document Summary

Distance- how far an object moves during motion (scalar) Displacement- straight line from initial to final point in specified direction (vector); indicates change in position form the starting point to the end point. Average speed- time rate of change of total distance, defined over a particular period of time (scalar) Average velocity- time rate of change of total displacement defined over a particular period of elapsed time (vector) Instantaneous velocity- velocity at any time --> speedometer reading (vector) Uniform motion- motion where the speed and direction remains unchanged i. e. velocity is constant. Non-uniform motion- velocity is not constant--> speed is changing or direction is changing. *in non-uniform motion average velocity is calculated over finite period of time using slope of the line connecting 2 points. *sign of acceleration indicates where object is speeding up or slowing down: Vectors in 2d: magnitude of vector is length=speed; have both magnitude and direction. *place vectors head to tail; always points from tail of.
