Kepler's second law of planetary motion
If you increase the distance from the sun, the planet moves slower.
Kepler's third law of planetary motion
If you increase the distance from the sun, it will increase the time to move around the sun.
Newton's 1st Law of Motion
If an object is moving at a constant speed, then it will continue to move at constant speed unless acted upon by an outside force.
If the masses of two objects increase, then the force of gravity between the two objects will
If the force with which you push an object increases, then the acceleration of that object will
If the mass of an object increases and the force on that object remains the same, then the acceleration of that object will
Would you weigh more or less on a planet with a smaller mass?
less because the planet has a smaller gravitational pull on you than earth
Neptune has the slowest speed because
it has the weakest gravitational attraction between the sun and planet.
Mercury has the fastest speed because
it has the strongest gravitational attraction between the sun and the planet
Difference between inner and outer planets
The inner planets are small, solid, and have no rings. The outer planets are large, gaseous, and have rings
If the two objects move further apart, what happens to the force of gravity between the two objects?
