2. Review Newton’s Laws Explanation Summary First inertia Second When an object is acted on by an unbalanced force, it will accelerate in the direction of that force. Third action-reaction
Buoyancy arises from the fact that fluid pressure increases with depth and from the fact that the increased pressure is exerted in all directions (Pascal's principle) so that there is an unbalanced upward force on the bottom of a submerged object. Since the "water ball" at left is exactly supported by the difference in pressure and the solid object at right experiences exactly the same pressure environment, it follows that the buoyant force on the solid object is equal to the weight of the water displaced (Archimedes' principle).
What will happen to an object with a density equal to the fluid in which it's submerged? - it will be suspended just under the surface
Bernoulli's Principle: faster moving air has lower pressure.
What do we call the combination of all forces, or the resulting force on an object? Net Force
