One way that mathematical models are used by scientists and engineers is to make predictions about how a system will behave. in the video, the engineers use a simple kinematics model to predict how much the glider would need to accelerate as it is pulled along the runway in order to launch. based on the aerodynamics of the glider, the engineers calculated it would need to reach a speed of 40 mph to successfully launch into the air. the roof is 160 feet above the ground, and the runway (built from tables on top of the peak of the roof) was about 60 feet long. the first question the engineers need to figure out is if it is theoretically possible to reach the desired launch speed given the length of the runway and the height of the tower questions 1. given this information, what must the acceleration of the glider be to reach the launch velocity by the end of the runway? (convert all values to si units.) 2. the engineer wants the glider to accelerate at a rate of 1.2g (11.6 m/s"). how does this compare to your result? why would the engineer over-estimate the acceleration?

When temperature of a substance increases, of its particles increase resulting in more between particles. real world applications of thermal expansion absolute zero (-273 degrees c) is the lowest possible temperature on the kelvin scale. it is a measure of where a substance has no kinetic energy. heat is a process of the . energy flows spontaneously from a object to a until equilibrium is reached. heat is measured in heat is transferred throughis a method of heat transfer that occurs between particles of matter that are in direct contact with each other. are poor conductors that impede / reduce the rate of heat transfer. is a method of heat transfer that occurs in fluids (non-solids) by means of currents. real world application of convectiona method of heat transfer through electromagnetic waves. when energy moves from one object to another inside a closed system, no energy is or in the system in the transaction. systems will spontaneously move to a state of organized energy or high disorder over time called
