hollistb said:So i have a problem with a question in which there is a falling raindrop where the mass and the radius are proportional and i have to find the acceleration with respect to radius and velocity.. I figured that bc it was falling its acceleration would be equal to g... but that seems to easy!
Gravity causes a raindrop to accelerate as it falls towards the ground. The speed of the raindrop will increase until it reaches its terminal velocity, which is the maximum speed at which the drag force of the surrounding air equals the force of gravity.
Raindrops vary in size due to a number of factors, including the temperature and humidity of the air, as well as the strength of updrafts within a cloud. Larger raindrops tend to form in warmer, more humid conditions, while smaller raindrops form in colder, drier conditions.
Air resistance, also known as drag, causes a raindrop to flatten as it falls. This is due to the pressure of the air pushing against the bottom of the raindrop, causing it to spread out and become more oblate in shape.
Surface tension is the force that holds the molecules of a liquid together at its surface. In the case of a falling raindrop, surface tension helps to maintain the spherical shape of the raindrop as it falls through the air, minimizing the effects of air resistance.
The impact force of a raindrop is directly related to its speed. The faster a raindrop falls, the greater its impact force will be upon hitting the ground. This is why larger raindrops can cause more damage than smaller ones.
