Does aluminum or lead have a greater buoyant force? Insight: Although each sphere experiences the same buoyant force, the lead sphere is more massive than the aluminum sphere and therefore the lead sphere still weighs more while submerged than does the aluminum sphere. Is lead buoyant? The specific gravity of lead is 11.34 – which […]

Does the initial velocity affect acceleration?
Does the initial velocity affect acceleration? Initial velocity is independent of the slope of the graph; that is, the acceleration. Does a heavier object hit the ground first? In other words, if two objects are the same size but one is heavier, the heavier one has greater density than the lighter object. Therefore, when both […]
