• 1. Which of the following describes acceleration correctly? A. It describes how fast is an objects motion.B. An object is accelerating if it is changing its velocity.C. It refers to the change in position with respect to its reference point.D. Acceleration is defined as the rate of change of the object's position with respect to a frame of reference and time.2. The following conditions shows that an object accelerates, except: A. When the object’s velocity changed.B. When an object in constant speed changed its direction.C. When an object in constant speed suddenly slows down.D. When an object is constantly moving in the same speed in a straight line.3. You are riding in a car with a constant speed of 40 km/h and then the car turned left without changing the speed. Is there an acceleration that took place? A. Yes, because the speed of the car did not change.B. No, change in direction does not pertain to acceleration.C. No, because the car did not slow down or increase its speed.D. Yes, because there was a change in direction as the car turned left.4. Why does a motorbike accelerate when it is travelling around in a circular path in a constant speed? A. Because it speeds upB.
