Circular Motion and Conservation

Circular motion

The act or process of moving in circle.

Centripetal acceleration

The acceleration toward the center of the circle in order to keep an object traveling in a circular path.

Centripetal force

The force that causes centripetal acceleration.

2*pi*r

Circumference

Newton’s Universal Law of Gravitation

The law states that every object in the universe attracts every other object with a force along an imaginary line between them.

The universal gravitation constant

G = 6.67×10^-11

Kepler’s first law

The path of each planet around the sun is an ellipse with the sun at one focus.

Kepler’s second law

The radius from sun to plant sweeps out equal areas in equal time.

Kepler’s third law

Square of the ratio of two planet’s periods equals the cube of the ratio of two planet’s average radius from the sun.

Einstein’s explanation of gravity

Gravity is a result of the warping, or curving, of space and time, which made up the same space-time “fabric.”

Gravity waves

Newton’s description of gravity

Gravity is a force of attraction between all objects with mass in the universe.

Ac = v²/r

Centripetal acceleration’s formula

Fc = (mv²/r) and (4*pi²*rm/T²)

Centripetal force’s formula

F = G*(m1m2/d²)

Formula of Newton’s universal law of gravitation

(T1/T2)² = (r1/r2)³

Formula of Kepler’s Third Law

v = (2*pi*r/T)

Velocity’s formula

Fc = W/Tan0

Centripetal force’s formula based on weight and angle.

%Error = (Fc1 - Fc2)*100%/Fc1

Percentage of error’s formula

T = (2*pi*r)/T = 2*pi*square root(r³/G*m)

Period of revolution’s formula
