Question

what happens to the velocity of a ball as it is dropped off a cliff? it increases at a non - uniform rate it is constant it increases at a uniform rate it decreases at a uniform rate

Explanation:

When a ball is dropped off a cliff, it is in free - fall. In the absence of air resistance, the only force acting on it is gravity. According to the laws of motion, the acceleration due to gravity near the Earth's surface is approximately constant ($g\approx9.8\ m/s^{2}$). Using the equation $v = v_0+at$ (where $v_0 = 0$ for a dropped object and $a = g$), the velocity increases over time at a constant (uniform) rate.

Answer:

C. It increases at a uniform rate
