Froggy Jumps Buoyancy Basics QuizVersion en ligne Test your buoyancy know-how. par Taylor 1 What force keeps objects afloat in a fluid by counteracting weight? a Electrostatic force b Buoyant force c Gravitational force 2 According to Archimedes' principle, the buoyant force equals the weight of the displaced fluid. If an object displaces 2 kg of water, what is the buoyant force? a Displacement is irrelevant b 0 g c 2 kg × g 3 Which variable increases buoyancy for a given object in the same fluid? a Object density b Volume of displaced fluid c Object mass 4 If an object's density is less than the fluid's density, what happens? a It floats b It remains neutrally buoyant c It sinks 5 What happens to pressure as depth increases in a fluid? a Pressure increases with depth b Pressure stays constant c Pressure decreases with depth 6 Which factor does not affect the buoyant force on an object in a fluid? a Fluid density b Object color c Displaced fluid mass 7 An object with same density as the fluid will: a Rise rapidly b Neutrally buoyant c Sink immediately 8 If you compress an object in a fluid, its buoyancy... a Always increases b Never changes c Can change due to volume change 9 Which equation relates buoyant force to fluid density? a Fb = ρ_fluid × g × V_displaced b Fb = m × g c Fb = ρ_object × g × V_total 10 A boat floats due to: a Relying on air inside hull only b Displacing water with enough volume c Adding mass to sink
