Final answer:
B. False. Only root events cannot be accelerated. Acceleration refers to the rate at which an object's velocity changes over time and is applicable to objects in motion.
Step-by-step explanation:
False. Only root events cannot be accelerated. In physics, acceleration refers to the rate at which an object's velocity changes over time. It is a vector quantity that has both magnitude and direction. Root events, such as an object at rest or moving with constant velocity, do not experience any change in velocity and therefore have an acceleration of zero. However, objects in motion can experience acceleration, whether it is increasing or decreasing in magnitude.
For example, if a car is initially traveling at a constant speed of 30 m/s and then increases its speed to 40 m/s in 5 seconds, we can calculate the acceleration using the formula:
acceleration = change in velocity / time taken
acceleration = (40 m/s - 30 m/s) / 5 s = 2 m/s^2
So, in this case, the car is experiencing a positive acceleration because its velocity is increasing. Therefore, the statement that only root events can be accelerated is false.
