- Identify and describe the universal forces acting within the nucleus
- Define Newton's law of universal gravitation and describe the factors affecting gravitational force
- Describe centripetal force and the type of motion it produces

Nevada Science Standards

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.

Tutorial

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
