What is acceleration
the change in speed of an object
change in velocity with time
|dw:1352654357456:dw|
ya change in velocity with respect to time simple...
Acceleration (velocity), in physics, the rate of change of velocity over time. An accelerating object is speeding up, slowing down, or changing the direction in which it is moving. Acceleration is a vector quantity—that is, it has both a magnitude and a direction. Acceleration describes both the magnitude of an object’s change in velocity, and the direction in which it is accelerating. Acceleration can thus involve changes of speed, changes of direction, or both. As acceleration is a rate of change of velocity over time and velocity is measured in meters per second (m/s), the units of measurement of acceleration are meters per second per second (m/s2).
