Only about five percent of the universe consists of the matter and energy that you and I see, feel, and experience. The other 95% of the universe consists of:
Write a paragraph on whether you believe that nature is mathematical mathematical. Is nature mathematical? Support your answer with specific evidence.
mass m = (density ρ)*(Volume)
distance d = (velocity ѵ)*(t)
velocity ѵ = (acceleration a)*(t) distance d = ½acceleration a)*(time t)² distance d = ½acceleration of gravity g)*(time t)² momentum p = (mass m)*(velocity ѵ) gravitational potential energy = (mass m)*(acceleration of gravity g)*(height) Kinetic energy = ½(mass m)*(velocity ѵ)²
