Build Your Own Robot Arm
Engineers team up to design and construct an 18-inch-long robotic arm that can successfully pick up a paper cup. Each group is given the exact same set of materials, but it is up to them to decide what to use and how to use it. It is a...
Curated OER
Motion and Forces
Unbalanced forces and the way that they create a movement is explained in this nice succinct collection of slides. There are a number of bullet points on these 5 slides, but the information is logical and easy to understand.
Curated OER
Force Diagrams
Seeming incomplete, this slide show introduces physical science novices to the balancing of forces and drawing force diagrams. The first seven slides work well to meet this purpose. The remaining slides, however, turn viewers over to...
Curated OER
Pressure and Moments
Each slide gives relevant equations and a number of explanations and examples, for the situations comparing pressure or moments to external control factors. The necessary conditions for particular situations are labeled and your pupils...
Curated OER
Labeling Forces Correctly!
Define six common forces: propulsion, air resistance, water resistance, friction, gravity, and upthrust. A picture of a Smart Car is displayed with arrows showing all of the forces acting on it when it is motion. A picture of a rubber...
Curated OER
Pushy Kids in Physics
Students examine the concepts of balanced forces, unbalanced forces, and resulting net forces. They participate in a force and motion demonstration by pushing students in various directions, and calculating and identifying the resulting...
Curated OER
Cruising Aircraft and Balanced Forces
Pupils, after reading an explanation from a NASA Web-based textbook, demonstrate an understanding of the text by applying it to questions involving cruising aircraft and balanced forces.
BioEd Online
Bio Ed Online: Introduction to Force and Motion
How is the motion of an object affected by forces that act on that object? Can you predict how the motion of an object will be affected by balanced and unbalanced forces? Is there a relationship between force, mass, and acceleration? In...
Physics Classroom
The Physics Classroom: Determining the Net Force
Online classroom site explaining the concept of balanced and unbalanced forces. The site has examples and exercises for the student to review and try.
BBC
Bbc: Bitesize: Science: Energy, Electricity and Forces: Unbalanced Forces
Explains abut unequal forces acting on an object and what would be observed. Also explains what the resultant force is and how it is calculated.
Science Education Resource Center at Carleton College
Serc: Balanced Forces
In this activity the students will learn the scientific definition of force. The students will see different examples of forces on an object and will gain an understanding that there are at least two forces acting on an object at all...
Exploratorium
Exploratorium: Structures Around the World
How does that bridge stay up? What are the forces acting on that column? This site helps students understand how structures can be built by having them build their own. Also provides images of real structures for kids to compare with...
Physics Classroom
The Physics Classroom: Vectors: Forces in Two Dimensions:equilibrium and Statics
Through examples and practice problems, this interactive tutorial helps students understand forces that are in a state of equilibrium with a net force of zero.
Concord Consortium
Concord Consortium: Nonbonding
Bring two molecules together and observe potential energy changes.
University of Virginia
University of Virginia: Rotational Motion
A page describing rotational equilibrium and non-equilibrium situations. Includes graphics, equations, and many examples.
BBC
Bbc Schools: Revisewise Science: Forces
Use this site to review information about forces, concentrating on balanced and unbalanced forces. The information is provided in an interactive activity. There is also a factsheet presenting information on balanced and unbalanced...
