<p>Notes</p>
<p>The following topics are covered in this chapter.</p>
<ul data-class="ListBulleted"><li>
State Newton's Law of Universal Gravitation: Every particle in the universe
attracts every other particle with a force which is directly proportional to the
product of their masses and inversely proportional to the square of the
distance between their centres
</li>
<li>Use the equation for Newton's Law of Universal Gravitation to solve
problems 1 2

F G m m
r
</li>
<li>Define weight (Fg) as the gravitational force the Earth exerts on any object
on or near its surface
</li>
<li>Calculate the acceleration due to gravity on any planet using the equation:

</li>
<li>Calculate the gravitational force on an object on other planets with different
values of gravitational acceleration.
</li>
<li>Distinguish between mass and weight
</li>
<li>Know that the unit of weight is the newton (N) and that of mass is the
kilogram (kg)
