... Question: How about tides due to the sun? The sun’s gravitational force on Earth is 180 times as large as that of the moon’s pull on Earth. So, what about ocean tides due to the sun?? Why are these not 180 times as strong as those due to the moon? Because tides happen due to differences in grav pul ...

... Summary of Newton’s Three Laws • An object tends to remain at rest, or, if moving, to continue moving at constant speed in a straight line (1st Law). Objects tend to resist changes in motion (inertia) – mass measures this. • (2nd Law) When there is a net force on an object, it will accelerate: a = ...
