Exam 6: Gravity, Projectiles, and Satellites

A satellite describes an elliptical orbit about a planet. The satellite travels much faster when it is directly over a

A bullet fired horizontally from a rifle begins to fall

Two objects move toward each other because of gravity. As the objects get closer and closer, the acceleration of each

A rock is thrown upward at 50 degrees with respect to the horizontal. As it rises, its horizontal component of velocity

According to Newton, doubling the distance between two interacting objects

After a rock thrown straight up reaches the top of its path and then falls a short distance, its acceleration is (neglect air resistance)

A hunter on level ground fires a bullet at an angle of 10 degrees above the horizontal while simultaneously dropping another bullet from the level of the rifle. Which bullet will hit the ground First?

Compared to the period of satellites in orbit close to the Earth, the period of satellites in orbit far from the Earth is

A black hole is

An object is placed exactly halfway between the Earth and moon. The object will fall toward the
