Phet forces and motion basics worksheet answers

Students who show understanding can: (9-12) Analyze data to support the claim that Newton's second law of movement describes the mathematical relationship between the net force on a macroscopic object, its mass, and its acceleration. (HS-PS2-1) Forces and Motion (PS2. A) The movement of an object is determined by the sum of the forces working on it; if the total force on the object is not zero, its movement will change. The larger the mass of the object, the greater the force needed to achieve the same change in movement. For a particular object, a larger force causes a greater change in movement. (6-8) All positions of objects and the directions of forces and movements should be described in a randomly chosen frame of reference and randomly selected size units. To share information with other people, these choices must also be shared. (6-8) Newton's second law accurately predicts changes in the movement of macroscopic objects. (9-12) Cause and effect (K-12) Cause and effect relationships can be used to predict phenomena in natural or designed systems. (6-8) The development and use of models (K-12) Modeling in 9-12 builds on the base-8 and progresses to the use, synthesis and development of models to predict and demonstrate relationships between variables between systems and their components in the natural and designed worlds. (9-12) Developing and using a model based on evidence to illustrate the relationships between systems or between components of a system. (9-12) Using mathematics and computational thinking (5-12) Mathematical and computational thinking at level 9-12 builds on the basic 8 and progresses to the use of algebraic thinking and analysis, analyze, represent, and represent computational tools for statistical analysis, and computational tools for statistical analysis, including trigonometry functions, exponential and logarithms, and computational tools for statistical analysis. Simple computational simulations are created and used based on mathematical models of basic assumptions. (9-12) Use mathematical representations of phenomena to describe explanations. (9-12) Create or review a simulation of a phenomenon, designed device, process or system. (9-12) 4E. Energy transformations 6-8: 4E/M2. Energy can be transferred from one system to another (or from one system to its environment) in different ways: 1) thermally, when a warmer object comes into contact with a cooler; (2) mechanically, when two objects push or pull together over a distance; 3) electrical, when an electrical source such as a battery or generator is connected to an electrical device in a full circuit; or 4) by electromagnetic waves. 4F. Motion 3-5: 4F/E1a. Changes in speed or direction of movement are by forces. 3-5: 4F/E1bc. The greater the power, the greater the movement change will be. The more massive an object is, the less effect a particular force will have. 6-8: 4F/M3a. An unbalanced force that works on an object changes the speed or direction of motion, or both. 9-12: 4F/H1. The change of motion (direction or speed) of an object is to the force applied and inversely proportional to the mass. 9-12: 4F/H4. When one thing exerts one force on the other, the same amount of force is exerted on it. 11B. Models 6-8: 11B/M4. Simulations are often useful in modeling events and processes. Back to HTML5 Version Force Motion Friction Speed Newton's First Law Explore the forces at work when pulling against a cart and pushing a refrigerator, crate or person. Create an applied force and see how objects move. Change friction and see how it affects the movement of objects. Example learning goals Identify when forces are balanced versus out of balance. Determine the sum of forces (net force) on an object with more than one force on it. Predict the movement of a zero net-force object. Predict the direction of movement with a combination of forces.
