Immovable Object vs. Unstoppable Force

Gecko published on



inertial frame of reference = if no external force is acting on a body it will stay at rest or remain in uniform motion

the second law of thermodynamics = the state of entropy of the entire universe, as an isolated system, will always increase over time

momentum = the quantity of motion of a moving body, measured as a product of its mass and velocity


accelerate = begin to move more quickly

infinite = having no limits

transparent = you can see through it very clearly

barrel down = move quickly and forcefully

velocity = speed
