Acceleration Lab

• If there is change in speed or direction of body, there is acceleration in body
• If there is acceleration in the body, its velocity is increasing. In this case acceleration is taken as positive and its direction is in the direction of velocity
• If the speed of body is decreasing, then the acceleration produced is negative. In this case it is called deceleration and it is taken as negative and its direction is opposite to the direction of velocity

$$ Distance = speed \times time$$ $$ displacement = velocity \times time$$ $$a=\frac{v_{f}-v_{i}}{t}$$
