Forces and Fluids

A state of matter that spreads out and fills the entire space it occupies.

The resistance experienced by an object moving through a fluid, such as air or water.

The upward force exerted by a fluid on an object that is submerged or floating in it.

An object floats if its weight is less than the buoyant force acting on it.

Water has a higher density than air, which affects the drag force experienced by objects moving through them.

The drag force is higher in water due to its higher density compared to air.

Gases can occupy different volumes depending on the shape and size of their container.

An object submerged in a fluid experiences a buoyant force equal to the weight of the fluid it displaces.

An open parachute increases drag force, making it harder to fall quickly.

A state of matter with a fixed shape and volume, where particles are closely packed together.
