Q

Who developed the heliocentric theory? Who contributed? How so?

44
Q

What concept did Sir Isaac Newton introduce?

A

His Three Laws of Motion

45
Q

Newton’s First Law of Motion

A

46
Q

Another name for Newton’s first law of motion

A

Law of Inertia

47
Q

Newton’s Second Law of Motion

A

Acceleration is produced when a force acts on a mass. The greater the mass of the object being accelerated the greater the amount of force needed.

48
Q

Newton’s Third Law of Motion

A

For every action there is an equal and opposite reaction.

49
Q

What are tides a result of?

A

Moon’s gravity acting on water of oceans.

50
Q

What did the law of gravity explain?

A

Explained how planets stayed in their orbits.

51
Q

What did the law of gravity provide?

A

Definitive mathematical support for the Copernican system and a foundation for Einstein’s later discoveries.
