Closer , Greater
Name the types of energy we learned about in class (Hint there's only 2).
Kinetic Energy and Potential Energy
What 2 factors effect kinetic energy?
Mass and Speed
The tendency to push other objects away from it.
Repulsive
What is Force?
What is A push or pull that interacts with other object?
Why do all the other planets in our solar system revolve around the sun?
The Sun has the greatest mass of any object in the solar system. As such, everything else will be attracted toward it.

No matter where you are located on Earth, when you drop an object, it will fall____ _____.
Towards Earth
Stationary spot for measuring distance and direction.
Reference Point
_________ is also known as motion energy

What is an electromagnetic force?
It is charged particles that act on each other across a distance. The particles usually fall into a line or pattern.
