force and acceleration
... Mass is a measure of the amount of matter in an object. As already mentioned, mass depends on the number and kinds of atoms in the object. Weight, however, depends on gravity. You would weigh less on the Moon, for example, than you do on Earth. Why? The Moon's gravity is weaker than Earth's, so you ...

3 Newton`s First Law of Motion—Inertia
... Galileo tested his idea by rolling balls along plane surfaces tilted at different angles. • A ball rolling down an inclined plane speeds up. • A ball rolling up an inclined plane—in a direction opposed by gravity—slows down. • A ball rolling on a smooth horizontal plane has almost ...

On the other hand, this energy can be kept in the radiation field in very many ways, essentially, since the electromagnetic field has very many degrees o ...

Chapter 6 Impulse and Momentum Continued
... Chapter 6 is about the COLLISION of TWO masses. To understand the interaction, both masses must be considered. Newton's 3rd Law plays a very important part. Collisions involve two new concepts: Impulse and Momentum. Impulse concept leads to the Momentum definition. Also applied to two (or more) mass ...
