A train is resting on a track when another train with several more cars bumps it and causes it to move forward 10 meters. This is an example of acceleration because:

in simple terms, the principle states that the buoyancy force on an object is equal to the weight of the fluid displaced by the object, or the density of the fluid multiplied by the submerged volume times the gravitational acceleration, g. this is also known as upthrust.

truck y has a greater velocity than truck x.
