Basic purpose of this lecture is to present on How to Calculate Acceleration. Acceleration is the rate of change of velocity of an object. where a is acceleration, v is the final velocity of the object, u is the initial velocity of the object and t is the time that has elapsed. This equation can be rearranged to give: v = u + at. Here also focus on Types of acceleration: Increasing speed; Example: Car speeds up at green light. Decreasing speed; Example: Car slows down at stop light. Changing Direction; Example: Car takes turn.
