Do all objects in free fall reach terminal velocity because I thought objects in free fall always accelerate with 9.8 m/s/s so why is there a point where they stop accelerating

Expert Solution

The concept of terminal speed arises when we have an opposing force along with gravity present in a system. When this opposing force is absent, then the objects in a free fall will keep accelerating with the acceleration g and the concept of terminal speed could not be applied here.

The opposing force here should be a force which is directly proportional to the velocity of the object, and so as the object increases its velocity due to the acceleration due to the gravity, the value of the opposing force keeps on increasing.

In case we have an opposing force, for example, the air resistance or the drag force experienced by a ball which is falling inside a liquid then in that case after some time the resistance force or the opposing force becomes exactly equal to the force of gravity and in that case the total force on the object becomes zero and so the acceleration becomes zero and so it keeps on moving with the same velocity for the rest of the journey which we call the terminal speed.

Calculate the terminal velocity in free fall of a bowling ball (mass of 7.2 kg, diameter of 21.6 cm) and a basketball (mass of 0.51 kg, diameter of 23.85 cm). The bowling ball can be considered a smooth sphere (Cd = 0.1), while the basketball can be considered a rough sphere (Cd = 0.4). What would be the terminal velocity of the basketball if we considered it a smooth sphere?

Free Fall on Different Worlds Objects in free fall on the earth have acceleration ay=−9.8m/s2ay=−9.8m/s2. On the moon, free fall acceleration is approximately 1/61/6 of the acceleration on earth. This changes the scale of problems involving free fall. For instance, suppose you jump straight upward, leaving the ground with velocity vivi and then steadily slowing until reaching zero velocity at your highest point. Because your initial velocity is determined mostly by the strength of your leg muscles, we can assume...

11) When we solved problems dealing with objects in free-fall, we often exploited a symmetry that led to the conclusion that the time it takes an object to go from a starting height to a maximum height (where the vertical (y-direction) velocity is zero) is the same as the time that it takes for the object to fall from that maximum height back to the starting height. If we introduce air resistance as a force similar to a friction force,...

How do I calculate time before an object reaches the ground during free fall, which includes items such as terminal velocity and other realistic factors. Please provide all formulas and what each variable means with units. Do not give me a basic entry physics general equation. You may use any complex formula including what ever variables needed such as drag coeff, surface area, etc.

As everybody knows that Black objects are black because almost all the light that falls on them is absorbed into the material. Little or no light is reflected back toward our eyes, therefore we see black. It is also known that, since black objects absorbs all the light they ultimately become heated-up..! If we see the snow in visible light, It appears to be White. But in the Infrared, it appears to be black. Does that mean that the Snow...
