  3. Every body contintues in a state of rest, or in a state of uniform motion in a straight line, unless it is compelled to change that state by a force acting upon it.

  4. Every body contintues in a state of rest, or in a state of uniform motion in a straight line, unless it is compelled to change that state by a force acting upon it. Orbital Velocity of Earth is 29.8 km/sec Radius of Earth Orbit (A.U.) is 1.496 x 108 km Acceleration is Velocity2 ÷ Radius What is the centripital acceleration of the Earth, that keeps it in orbit around the Sun?

  5. Every body contintues in a state of rest, or in a state of uniform motion in a straight line, unless it is compelled to change that state by a force acting upon it. Orbital Velocity of Earth is 29.8 km/sec Radius of Earth Orbit (A.U.) is 1.496 x 108 km Acceleration is Velocity2 ÷ Radius What is the centripital acceleration of the Earth, that keeps it in orbit around the Sun? (29.9 km/sec)2 ÷ 1.496 x 108 km = .000005932 km/sec2 Or, .005932 meters/sec2

  6. When a force "F" acts upon a body of mass "m", it produces in it an acceleration "a", that is equal to the force divided by the mass. Therefore, a=F/m, and F=ma

  7. When a force "F" acts upon a body of mass "m", it produces in it an acceleration "a", that is equal to the force divided by the mass. Therefore, a=F/m, and F=ma Earth has a mass of about 5.97 x 1024 kg Acceleration is about .006 m/s2 What is the centripital force of gravity pulling the Earth towards the Sun?

  8. When a force "F" acts upon a body of mass "m", it produces in it an acceleration "a", that is equal to the force divided by the mass. Therefore, a=F/m, and F=ma Earth has a mass of about 5.97 x 1024 kg Acceleration is about .006 m/s2 What is the centripital force of gravity pulling the Earth towards the Sun? F = .006 m/s2 x 5,970,000,000,000,000,000,000,000 kg = 3.582 x 1023 N = a whole bunch of force.

  9. Every action has an equal and opposite reaction. The centripital "pull" of the Sun's gravity is opposed almost exactly by the "push" of the Earth trying to continue to move in a straight line.

  10. Every particle of matter in the Universe attracts every other particle of matter in the universe with a force that is directly proportional to the product of the masses of the particles, and inversely proportional to the square of the distance between them.

  11. Every particle of matter in the Universe attracts every other particle of matter in the universe with a force that is directly proportional to the product of the masses of the particles, and inversely proportional to the square of the distance between them. This force is a property of space itself, and probably not something that moves within space, although a particle called a "graviton" has been postulated, and made popular on "Star Trek".

  12. "Can't Live Without You Kurt", and "Don't Leave Me Donna" are convinced that the universe is pulling them together. This is much to the chargrine of the others in the hallway who must watch the P.D.A., but anyway. What is the gravitational pull of the two, when they are 1 meter apart? Kurt has a mass of 80 kilograms, and Donna has a mass of 60 kilograms. The gravitational constant is 6.67 x 10-11(N m2/kg2). F=(Gm1m2/r2). We shall dance, and we shall sing, and then one day we shall trade a ring!!!

Kurt has a mass of 80 kilograms, and Donna has a mass of 60 kilograms. The gravitational constant is 6.67 x 10-11(N m2/kg2). F=(Gm1m2/r2). F = (6.67 x 10-11 • 60 •80)÷(1 • 1) F = .000003216 Newtons. Far, far less than the force of a snowflake hitting the ground.

  14. What goes up might not come back. Does is come down?
