Studied by 8 peopleCircular 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.”
LIGO
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
