What is Enterprise?
The velocity equation (in full)
What is "velocity equals distance divided by time"?
Newton's First Law of Motion
What is "An object at rest will remain at rest and an object in motion will continue in a straight line at the same speed unless an unbalanced force acts upon it?"
The Law of Conservation of Energy
What is "Energy can neither be created nor destroyed, only changed in form"?
The equation for momentum (in full)
What is "momentum equals mass times velocity"?
Truth (give the definition)
What is the way things really are?
