Boats float because water pushes them up!

This push is called buoyancy.

🛶 A boat has a hollow shape with air inside.

This helps it float on water

🪨 A rock sinks because it is small and heavy.

🛶 A boat floats because it spreads its weight and pushes water away.

formula of buoyancy.

Fb​=ρgV

• F₍b₎ = buoyant force (the water pushing up)

• ρ (rho) = how heavy the water is

• g = gravity

• V = amount of water pushed away
