Damon Pryor Physics Notes 12/11/06 2.5-2.7 + 4.8 Instantaneous Velocity: how fast a particle moves at a given instance, V= lim (x 0) delta x/delta t = dx/dt (the derivative of x over the derivative of t). Speed: is the magnitude of velocity; basically speed is instantaneous velocity with out direction. Instantaneous Acceleration: the derivative of velocity over the derivative of time. dx/dt.

Unformatted text preview: Acceleration has both magnitude and direction. Constant Acceleration: x-x0 =v0(t)+1/2a(t)2 (raise to the second power). The velocity of a particle depends on the reference frame. Observers on different frames of reference will measure the same acceleration for a moving particle, if they are moving at a constant velocity relative to each other....
