Which ball will reach terminal velocity first?
Answer and Explanation: Since the weight of the water-filled ball would be more, therefore it will have to attain more velocity to attain terminal velocity. Therefore, the ball filled with air reaches first to its terminal velocity.
At what height does a tennis ball reach terminal velocity?
After the ball has dropped about 100 meters (around 25-30 stories for a normal building), the force of air resistance becomes large enough to balance the force of gravity; at this point, the ball has reached its “terminal velocity”, and falls at a constant rate without further acceleration.
Why does the ball reaches terminal velocity?
The force of air resistance is approximately proportional to the speed of the falling object, so that air resistance increases for an object that is accelerating, having been dropped from rest until terminal velocity is reached. …
What is terminal velocity and how is it reached?
Terminal velocity is defined as the highest velocity that can be achieved by an object that is falling through a fluid, such as air or water. When terminal velocity is reached, the downward force of gravity is equal to the sum of the object’s buoyancy and the drag force.
Which ball will hit the ground first if dropped at the same time and at the same height in a perfect vacuum and why?
Therefore, when both objects are dropped from the same height and at the same time, the heavier object should hit the ground before the lighter one.
What is terminal velocity of a falling object?
Terminal velocity is the maximum velocity (speed) attainable by an object as it falls through a fluid (air is the most common example). It occurs when the sum of the drag force (Fd) and the buoyancy is equal to the downward force of gravity (FG) acting on the object.
What is the velocity of a tennis ball?
The final velocity of the tennis ball is calculated to be -1.37ms‾¹, while the distance from the peak height to final velocity is 0.10m….Equations of Motion.

Distance to Max Height (m) | 1.43 | 1.13 |
Time to Reach Max Height (s) | 0.54 | 0.48 |
Distance from Max Height to end (m) | 0.10 | 0.38 |

When you drop a plastic ball and a metal ball from the same height at the same time which ball falls to the ground first?
As both balls fall, the ball of greater mass experiences a greater downward force of gravity, as Force = mass * acceleration (F=ma). As both balls have the same acceleration g, the ball with more mass, the metal one, will have a greater force F.
