What is....................whatever you liked learning most about in Science this year!!
In the orbit of a planet or other body in the solar system, the point that is CLOSEST to the sun
What is Perihelion?
In the orbit of a planet or other body in the solar system, the point that is FARTHEST from the sun
What is Aphelion?
a law that states that ALL objects in the universe attract each other through gravitational force.
What is the law of universal gravitation?
The strength of the force of gravity depends on the product of the masses of two objects. Therefore, as the masses of two objects increase, the force that the objects exert on one another does what?
What is increases?
Gravitational force is inversely proportional to the square of the distance between two objects. Therefore, as the distance between two objects increases, the force of gravity between them does what?
What is decreases?
