Which statement best explains why objects are pulled toward Earth's center?
Earth has a magnetic force that is strongest at its core
Earth has a much greater mass than objects on its surface
the weight of the atmosphere pushes objects toward Earth's surface
the strength of the Sun's gravity pushes down on objects at Earth's surface
Which of these describes what happened when Galileo dropped two cannonballs with different masses from the same height.
The heavier cannonball reaches the ground first
The lighter cannonball reaches the ground first
They reach the ground at the same time.
The results depend on the volumes and the masses

The force that keeps satellites in orbit around Earth is
magnetic
friction
electrical
gravity
What effect does friction have on a moving object?
it causes the moving object to slow and eventually stop
it causes the moving object to speed up
it keeps the moving object moving in the same direction forever
it causes the moving object to turn around and move in the opposite direction
