Density is the measure of how much mass is packed into a certain volume. In general, objects with higher density will fall faster than objects with lower density. This is because the higher density object has more mass and therefore more gravitational force acting on it, causing it to accelerate faster towards the ground.
This is because the feather has a lower density compared to the rock. Even though both objects experience the same gravitational force, the feather has a larger surface area and experiences more air resistance, slowing down its fall.
Yes, the shape of an object can affect its speed when falling through air. Objects with a more streamlined shape, like a pointed object, will experience less air resistance and therefore fall faster. Objects with a larger surface area, like a flat object, will experience more air resistance and fall slower.
Altitude, or the height at which the object is dropped, does not affect the speed of a falling object. This is because the force of gravity is constant regardless of altitude. However, at higher altitudes, there is less air resistance which can cause an object to fall faster.
No, there is no limit to how fast an object can fall due to density. However, as an object approaches terminal velocity (the maximum speed it can reach while falling), the effects of density become less significant and other factors, such as air resistance, play a larger role in determining its speed.
