Technical information, teaching suggestions, and related resources that complement this Interactive are provided on the Notes page. The first law says that an object will stay at rest unless an external force acts upon it, in which case the object will change its motion. He actually has laws of motion, but many people consider it laws of physics. Learners and Instructors may also be interested in viewing the accompanying Notes page. Today, almost no fan of physics, big or small, has gotten by without hearing of Sir Isaac Newton and his laws of physics. Then follow it up with the Concept Checker. Our Force simulation is now available with a Concept Checker. ![]() These two activities were designed with the intent of being used by classroom teachers with their classes. Or if desired, The Physics Classroom has prepared two activities for a more directed experience. Users are encouraged to open the Interactive and explore. Learners can modify a variable, run the simulation, measure the acceleration and draw conclusions about what factors affect the acceleration. The amount of friction is altered by altering a coefficient known as the coefficient of friction. The environment allows a user to modify the amount of force applied to a box, the mass of the box, and the friction between the box and the surface it is pushed across. ![]() The Force Interactive provides an environment that allows the learner to explore the factors that affect the acceleration of an object when acted upon by an ubalanced force.
