When body moves with terminal velocity the acceleration in the body become
Correct answer: A. zero
- A. zero
- B. maximum
- C. variable
- D. infinite
Explanation
Terminal velocity is constant speed achieved by an object falling through a fluid (like air) when the force of gravity pulling it down is balanced by the force of air resistance pushing against it. This speed is constant(uniform) and the maximum speed that falling object can achieve.As velocity=constantΔ velocity =0Acceleration= Δ velocity/time=0/time =0

About Fluid Dynamics
Fluid flow is described through speed, pressure and density, including steady flow and the equation of continuity for conserving mass. Bernoulli's equation relates pressure, speed and height, while fluid drag and terminal velocity explain why a falling object eventually moves at constant speed when drag balances its weight.
