This podcast is part of the series: Forces

Creator: Blake and Kiley
School/Organization: Fairhope high School
Baldwin County School District
Overview:
This podcast is one of a series of podcasts that are designed to teach about the forces in our world. This particular podcast focuses on gravitational and nuclear forces. The students discuss Universal Gravitation, and nuclear forces and demonstrate each in the podcast. They also define the unit for force.

SC (912) Physical Science  6. Identify characteristics of gravitational, electromagnetic, and nuclear forces.   SC (912) Physical Science  7. Relate velocity, acceleration, and kinetic energy to mass, distance, force, and time. Interpreting graphic representations of velocity versus time and distance versus time Solving problems for velocity, acceleration, force, work, and power Describing action and reaction forces, inertia, acceleration, momentum, and friction in terms of Newton's three laws of motion Determining the resultant of collinear forces acting on a body Example: solving problems involving the effect of a tailwind or headwind on an airplane Solving problems for efficiency and mechanical advantage of simple machines   SC (912) Physical Science  8. Relate the law of conservation of energy to transformations of potential energy, kinetic energy, and thermal energy. Identifying the relationship between thermal energy and the temperature of a sample of matter Describing the flow of thermal energy between two samples of matter Explaining how thermal energy is transferred by radiation, conduction, and convection Relating simple formulas to the calculation of potential energy, kinetic energy, and work   SC (912) Physical Science  12. Identify metric units for mass, distance, time, temperature, velocity, acceleration, density, force, energy, and power.   SC (912) Physics  4. Describe quantitative relationships for velocity, acceleration, force, work, power, potential energy, and kinetic energy.   SC (912) Physics  8. Summarize similarities in the calculation of electrical, magnetic, and gravitational forces between objects. Determining the force on charged particles using Coulomb's law   SC2015 (912) Physical Science  7. Analyze and interpret data for one and twodimensional motion applying
basic concepts of distance, displacement, speed, velocity, and acceleration
(e.g., velocity versus time graphs, displacement versus time graphs,
acceleration versus time graphs).   SC2015 (912) Physical Science  8. Apply Newton's laws to predict the resulting motion of a system by constructing force diagrams that identify the external forces acting on the system, including friction (e.g., a book on a table, an object being pushed across a floor, an accelerating car).   SC2015 (912) Physics  1. Investigate and analyze, based on evidence obtained through observation or experimental design, the motion of an object using both graphical and mathematical models (e.g., creating or interpreting graphs of position, velocity, and acceleration versus time graphs for one and twodimensional motion; solving problems using kinematic equations for the case of constant acceleration) that may include descriptors such as position, distance traveled, displacement, speed, velocity, and acceleration.   SC2015 (912) Physics  2. Identify external forces in a system and apply Newton's laws graphically by using models such as freebody diagrams to explain how the motion of an object is affected, ranging from simple to complex, and including circular motion. a. Use mathematical computations to derive simple equations of motion for
various systems using Newton's second law. b. Use mathematical computations to explain the nature of forces (e.g., tension, friction, normal) related to Newton's second and third laws.
