Ability to calculate the average velocity of an object traveling a certain distance over a period of time. Models can be used to predict the behavior of a system, but these predictions have limited precision and reliability due to the assumptions and approximations inherent in models.Īlignment agreement: Thanks for your feedback! Science assumes the universe is a vast single system in which basic laws are consistent.Ī basic understanding of distance, time, velocity and acceleration.

relative positions of charged particles, compression of a spring) and how kinetic energy depends on mass and speed, allow the concept of conservation of energy to be used to predict and describe system behavior.Īlignment agreement: Thanks for your feedback! The availability of energy limits what can occur in any system. That there is a single quantity called energy is due to the fact that a system's total energy is conserved, even as, within the system, energy is continually transferred from one object to another and between its various possible forms.Īlignment agreement: Thanks for your feedback! Conservation of energy means that the total change of energy in any system is always equal to the total energy transferred into or out of the system.Īlignment agreement: Thanks for your feedback! Energy cannot be created or destroyed, but it can be transported from one place to another and transferred between systems.Īlignment agreement: Thanks for your feedback! Mathematical expressions, which quantify how the stored energy in a system depends on its configuration (e.g. This activity focuses on the following Three Dimensional Learning aspects of NGSS:Ĭreate a computational model or simulation of a phenomenon, designed device, process, or system.Īlignment agreement: Thanks for your feedback!Įnergy is a quantitative property of a system that depends on the motion and interactions of matter and radiation within that system. Determine how far an object will travel based on initial conditions.Ĭreate a computational model to calculate the change in the energy of one component in a system when the change in energy of the other component(s) and energy flows in and out of the system are known.Ĭlick to view other curriculum aligned to this Performance Expectation.Describe the trajectory of an object in projectile motion.The combination of a physical understanding of projectile motion and the mathematical ability to solve equations enables engineers (as well as young students) to predict projectile trajectories.Īfter this activity, students should be able to: NASA engineers apply projectile motion concepts as they predict the paths of meteorites that may enter the Earth's atmosphere or disrupt satellite transmissions. This includes machines such as motocross bikes made for launching off jumps to weapons such as missiles, turrets and high-powered cannons. Any engineered design that includes a projectile, an object in motion close to the Earth's surface subject to gravitational acceleration, requires an understanding of the physics involved in projectile motion. Understanding projectile motion is important to many engineering designs.
