P.12.B.2 Students know magnetic forces and electric forces can be thought of as different aspects of electromagnetic force. I/S
P.12.B.4 Students know the strength of the gravitational force between two objects increases with mass and decreases rapidly with distance. I/S
Next Generation Science Standards
HS-PS2-d Use mathematical expressions to represent the relationship between the variables in both Newton's Law of Gravitation and Coulomb's Law, and use these expressions to predict the gravitational and electrostatic forces between objects
HS- PS3-e Develop and use models of two objects interacting through a field to explain the changes in energy and the forces between the objects due to the interaction.
Read Chapter 12.4 Universal Forces
Outline the reading in your Science Notebook & include major points and diagrams/tables.
You should focus on the following essential questions:
- What force can attract and repel
- What force holds the nucleus together
- What is Newton's Law of universal gravitation
