Is it true that the thing that affects how fast it falls is the objects surface area?
Surface area is ONE thing that can affect how fast an object falls. Two forces determine how fast an object falls - the force of gravity and the opposing drag on the object from the medium it is falling through. In the case of an object falling in a vacuum, there is no drag so the object falls strictly according to the law of gravity. If an object is dropped through a fluid such as air or water, it can reach a terminal velocity where the force of gravity is exactly counterbalanced by the opposing drag on the object. In this case acceleration ceases - although motion does not. In other words, the object continues to fall, but it doesn't speed up. Drag force is a function of object velocity, viscosity of the fluid it is falling through, the surface area of the falling object, the surface roughness of the falling object, and the geometry of the falling object (spheres usually have less drag than cubes for example).
Does surface area of a falling object affect its motion?
Yes. Think of a glider, and then imagine folding its wings in half.
What are the advantages of higher proportion of surface area to volume?
- A higher surface area will increase heat loss as more heat can be radiated. - It may improve an object's ability to float on water. - Increases drag or air resistance when an object is moving - this is why parachutes are used to slow people down when falling.
What is the measure of how much surface an object has?
Area is the measure of how much surface an object has.
How does surface area different from area?
Surface area is the area of all the sides of a 3D object, but area could be anything. e.g. Area is the surface of a 2D object or if you say the area of all the sides, it means the same as Surface area. -----=-----=-----=-----=-----=-----=-----=-----=-----=-----=-----=-----=-----=-----= By Austin from Covenant Christian School
