5 True/False questions
How can a ship float? → the amount of water the ship displaces increases the buoyant force and therefore has a net force greater upwards than down.
How does a submarine dive? → the amount of water the ship displaces increases the buoyant force and therefore has a net force greater upwards than down.
What can you tell about an object if you know the density? → if it would sink or float.
What is area measure by? → Newtons
What is the formula for density? → force/area
