inertia | the tendency of a moving object to keep moving in a straight line |
buoyancy | an upward force exerted by a liquid on an object that causes the object to float. |
balanced forces | forces that act on an object without changing its motion |

motion | a change in position over time |
velocity | speed with direction |
distance รท time | the formula for calculating speed |
energy | the ability to perform work or change an object |
