Drawing Free-Body Diagrams Free-body diagrams are diagrams used to show the relative magnitude and direction of all forces acting upon an object in a given situation. A free-body diagram is a special example of the vector diagrams that were discussed in an earlier unit. These diagrams will be used throughout our study of physics. The size of the arrow in a free-body diagram reflects the magnitude of the force. The free-body diagram above depicts four forces acting upon the object. Practice Apply the method described in the paragraph above to construct free-body diagrams for the various situations described below. A book is at rest on a tabletop.

Trabajo y energía I: conceptos - Física Los conceptos de trabajo y energía son conceptos complicados de entender. El trabajo se simboliza como W (work en inglés). Este es la fuerza que necesitamos entregarle a un objeto para moverlo de un lado a otro: W = Fuerza por distancia. La energía es la forma en la que el objeto recibe el trabajo. Se habla de dos tipos de energías: Cinética: Tiene que ver con el movimiento Potencial gravitatoria Si tenemos un cuerpo y lo queremos mover debemos hacer una fuerza. La aceleración depende de la fuerza entregada y de la masa. La energía potencial gravitatoria depende de la ubicación del cuerpo. Momentum Car Crash Webquest Introduction Introduction A traffic accident occurred in a 35 km/hr speed limit zone on Millway Street in which a 3000-kg Cadillac Escalade SUV rear-ended a 2000-kg Subaru Outback Wagon that was stopped at a stop sign. The entire police investigative division has gone on vacation to Bora Bora to relax, so the mayor has contracted with you and your team of experts to determine what happened and what traffic laws were broken. Task Your team will provide the mayor with a detailed accident report (including all equations and work) that includes mass, velocity, and momentum of both vehicles both prior to and after the collision. The mayor has provided you with the following diagram drawn by police officers at the site of the accident: Process Each group member will choose one of the following roles. Evaluation Work will be evaluated based on the attached rubric. Conclusion Teacher Notes

Middle School Chemistry | Download Free Science Activities, Access Chemistry Multimedia, Find Information on Workshops Peso y masa - Física En este video trabajaremos con el peso de los cuerpos. En lo cotidiano, utilizamos el concepto de masa y de peso como sinónimos, no siendo así para la física. Cuando Newton estudió las causas del movimiento se dio cuenta que a un mismo cuerpo cuando se le aplica distintas fuerzas este se mueve a diferentes aceleraciones. Tomemos un ejemplo: Si tenemos un cuerpo de masa 10 Kg, nos preguntamos, cuánto pesa en la tierra considerando que esta tiene una gravedad de 9,8 m/s2 Peso = Masa por gravedad Peso = 10 kg x 9,8 m/s2 Peso = 98 Newton ¿Cuánto pesa en la luna que tiene una gravedad de 1,66 m/s2? Peso = 10 kg x 1,66 m/s2 Peso en la luna = 16,6 Newton Otro concepto de la dinámica muy importante es el principio de acción y reacción.

Mumbai Suburban Table tennis Association Physics and Motion The Shockwave Physics Studios consists of a collection of pages which feature interactive Shockwave files that simulate a physical situation. Users can manipulate a variable and observe the outcome of the change on the physical situation. Many of the animations are accompanied by an activity sheet which provides directions and procedural information for users. Such activity sheets were designed so that the animation could become a classroom-ready activity for use by students and teachers.

El encargado de estudiar las causas del movimiento fue Newton. Él descubrió que a un cuerpo de masa m para que pueda empezar a moverse hay que aplicarle una fuerza. De esa manera descubrió la siguiente fórmula: Fuerza = Masa por Aceleración. Las fuerzas pueden ser de distintas maneras ya que la fuerza es un vector y, como todo vector, va a tener un valor, una dirección y un sentido. Las fuerzas se grafican con un número, es decir F1, F2, F3. Si dos vectores tienen igual dirección e igual sentido simplemente los sumamos. Si dos vectores tienen igual dirección pero distinto sentido, la fuerza resultante será la resta de las mismas. Cuando tenemos una fuerza en ángulo, antes de poder sumarla con las otras fuerzas en los ejes debemos descomponerla. Componente x y Componente y Componente x = Fuerza por coseno del ángulo del eje x Componente y = Fuerza por seno del ángulo. Tenemos una F2 de 50 N
