Chapter_05_Gravity

Newton’s first law of motion is essentially a restatement of Galileo’s law of inertia.

True

False

Aristotle believed that objects falling to the ground fall at a constant rate of speed.

True

False

Galileo believed that motion stops in the absence of a force.

True

False

Newtonian gravity is often called universal mutual gravitation because every particle with mass in the Universe must attract every other particle.

True

False

Changing the direction of a moving body does not impact its velocity.

True

False

The escape velocity at a given distance from a planet is less than the circular velocity of an orbit around that planet at the same distance.

True

False

The Moon pulls more strongly on Earth’s near and far side than on its center.

	True False

	8 The apparent positions of stars around the sun during an eclipse have been used to prove the general theory of relativity. True False

	9 The neap tides occur at the new moon and full moon. True False

	10 Spring tides occur during the new and full lunar phases. True False

	11 Two objects in orbit around each other orbit their common center of mass. True False

	12 Newton’s third law states that forces occur in pairs acting in the same direction. True False

	13 If an object’s velocity equals or exceeds the escape velocity, it will follow a closed parabolic or hyperbolic orbit. True False

	14 The second postulate of special relativity states that the speed of light,

	when measured in a vacuum, is constant for all observers. True False

	15 Special relativity states the relationship between energy and mass as. True False
