Astro 7N Unit 1 with 100% correct answers 2024

Astro 7N Unit 1according to newton's second law of motion, if the net force acting on the object increases while the mass of the object remains constant, what happens to the acceleration? - correct answer acceleration increases if the earth were moved to half its current distance from the sun, how would the force of gravity by the sun on the earth change? - correct answer it would be four times stronger what did newton's law of universal gravitation tell us about how gravity works? - correct answer the force of gravity from the sun will be stronger on an object with more mass the earth radius is about 6400 km. if you were in orbit in the space station 150 km above the ground, the force of gravity you feel from earth would be - correct answer slightly weaker than when you are standing on earth if you were to sit on the ground, there would be a force due to gravity pulling you toward the earth. which of the following is true according to newton's 3rd law? - correct answer you are pushing the earth away from yourself with the same force what would happen to the earth if the sun's gravity somehow turned off instantaneously? - correct answer it would continue to move in a line in the same direction it was moving when the gravity turned off consider a planet whose rotation axis is not tilted with respect to its orbital plan. what are the seasons like on this planet? - correct answer there are no seasons if the earth rotated on its axis more slowly than it does now - correct answer the days would be longer if earth had its orbit changed so that at all points along its orbit it were always the same distance from the sun (circular orbit), how would this affect the seasons on earth? - correct answer they would be the same as they are now
