* ACCELEBRATION ** OBJECTIVES/GUIDE QUESTIONS 1. What is Acceleration 2. When is an object accelerating ** CONTENT Acceleration is a vector quantity that refers to how fast an object is changing is velocity voer a period of time, If the velocity is of an object is varying, then it is said to be accelerating *** HOW TO CHANGE ACCELERATION 1. By increasing its speed while traveling in a straight line 2. By decreasing its speed while traveling in a straight line 3. by changing its direction while traveling at a constant speed NOTE: THE FASTER THE THING, THE GREATER THE ACCELERATION *** FORMULA To calculate acceleration the formula below shows: a = Vf - Vi (final instatenous velocity - ------- initial instantenous velocity T divided by time interval) t = Vf - vi (final inst. velocity - initi. ------- velocity divided by time interval) a
