Part B: The fireball when moving . Part C: The change in the It __when moving . fireball's velocity was caused by So, its velocity is always Acceleration Due to Gravity For any projectile, the rate of acceleration is o The value of this acceleration on Earth is m/s. In other words, a falling object's velocity increases every second by i meters per second. s This acceleration is called the (g). .
