]You can probably think of several real-world situations in which an understanding of speed, distance and time is helpful. The concept of density is applicable to floating and buoyancy – which has many serious real-life applications. Can you think of some? Objects less dense than water will float on water. But water is not the only medium things can float on. Here is a video of a cannonball floating in mercury, a metal which is liquid at room temperature: Why do helium balloons float? Here is a video of an attempt to use helium balloons to lift a man off the ground:

An understanding of speed is needed before considering kinematic graphs:
