![]() ![]() Present to the class the Introduction/Motivation content.Conduct the pre-assessment true/false voting exercise, as described in the Assessment section.Gather materials and make copies of the Physics Tug of War! Worksheet.If the books are too heavy, the stack of two books will not move at all. Specifically, make sure that the books are light enough to permit the side with two books to move in Part 2 of the experiment. Test the activity to fine-tune the materials.This means that the airplanes have to push A LOT of air. This is especially important for airplanes because they are much heavier than the air molecules that they are pushing against. If the second person was 10 times heavier than the first, then the person who weighed 100 pounds would accelerate backwards 10 times as fast.Ĭan you think of any time that this has happened to you? Maybe on the playground or during sports? If you throw a tennis ball and a basketball with the same amount of force, which can you throw father? (Answer: Tennis ball.)Įngineers must consider the weight and mass of object when designing. This means that if a person who is 100 pounds pushed off of a person who is 200 pounds (twice as heavy), then the person who weighed 100 pounds would accelerate backwards twice as fast. Newton's second law of motion uses a mathematical equation to say that the force needed to move an object is proportional to the object's mass. ![]() Physics Tug of War!

International Technology and Engineering Educators Association - Technology Summarize numerical data sets in relation to their context, such as by:ĭescribing the nature of the attribute under investigation, including how it was measured and its units of measurement.įluently divide multi-digit numbers using the standard algorithm.įluently add, subtract, multiply, and divide multi-digit decimals using the standard algorithm for each operation. In order to share information with other people, these choices must also be shared.Įxplanations of stability and change in natural or designed systems can be constructed by examining the changes over time and forces at different scales. For any given object, a larger force causes a larger change in motion.Īlignment agreement: Thanks for your feedback! All positions of objects and the directions of forces and motions must be described in an arbitrarily chosen reference frame and arbitrarily chosen units of size. The greater the mass of the object, the greater the force needed to achieve the same change in motion. ![]() The motion of an object is determined by the sum of the forces acting on it if the total force on the object is not zero, its motion will change. Plan an investigation individually and collaboratively, and in the design: identify independent and dependent variables and controls, what tools are needed to do the gathering, how measurements will be recorded, and how many data are needed to support a claim.Īlignment agreement: Thanks for your feedback! Science knowledge is based upon logical and conceptual connections between evidence and explanations.Īlignment agreement: Thanks for your feedback! This activity focuses on the following Three Dimensional Learning aspects of NGSS: ![]() Plan an investigation to provide evidence that the change in an object's motion depends on the sum of the forces on the object and the mass of the object.Ĭlick to view other curriculum aligned to this Performance Expectation ![]()
