Forces and Fluids

Front

What is a gas?

Back

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

Front

What is drag force?

Back

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

Front

What is buoyant force?

Back

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

Front

What determines whether an object will float or sink in a fluid?

Back

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

Front

What is the difference between density of water and air?

Back

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

Front

What happens to the drag force when running in water compared to running on dry land?

Back

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

Front

What is the relationship between volume and the state of matter for gases?

Back

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

Front

What is the principle of Archimedes?

Back

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

Front

What is the effect of an open parachute on drag force?

Back

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

Front

What is a solid?

Back

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