The Galileo version describes projectile motion as a combination of horizontal motion with a constant velocity, equal to the projectile initial horizontal velocity component, and vertical motion with constant acceleration and an initial velocity equal to the projectile's initial velocity component. In the mood to try something different? This unique resource models two views of projectile motion. Projectile Motion: Galileo and Newton Simulation.If you don’t have Tracker yet, here’s a link to the free download: Download Tracker Video Analysis and Modeling Tool This resource uses the free Tracker Video Analysis tool to measure and analyze the motion of an angry bird projected from a slingshot to hit a pig. Projectile Motion Simulation: Problem-Based Learning Investigation The lesson is aimed at beginners as they explore variables affecting trajectory. Learners take the role of a military artillery officer with the task of explaining factors that affect the path of a projectile fired from a cannon. Can you set the initial conditions so that you hit the target? Teachers: For a unique activity to accompany this simulation, here’s a Problem-Based Learning exercise developed by a high school teacher. By manipulating angle, initial speed, mass, and air resistance, concepts of projectile motion come to light in a fun and game-like environment. In this simulation, students can fire various objects out of a cannon, including a golf ball, football, pumpkin, human being, a piano, and a car. The simulation is an HTML5 simulation that was designed with iPads, Chromebooks, and smart phones as the target device. The simulator is accompanied by three separate exercises that emphasize various aspects of projectile motion. The velocity vector components, acceleration vector, and the trajectory trace can be toggled off and on. The trajectory, range, and time of fight are displayed. This projectile simulator allows students to alter the launch speed, launch height and launch angle of a projectile. Non-Horizontally Launched Projectiles - Problem-Solving.Horizontally Launched Projectiles - Problem-Solving.Horizontal and Vertical Components of Velocity.Characteristics of a Projectile's Trajectory.List the error sources the simulation eliminates or minimizes.Motion and Forces in Two Dimensions Chapter, Lesson 2 Describe why using the simulation is a good method for studying projectiles. Try for at least 2 other combinations of launch velocity and angle.Ħ.Test your predicted value using the simulation. Calculate the horizontal range when the initial velocity is 25m/s and the launch angle is 20 deg to the horizontal.Does the simulation work as predicted? Show your working clearly Use SUVAT equations to make predictions for the horizontal range of projectiles launched at different angles and speeds. You should also add force vectors (ignore air resistance). The simulation allows you to add the velocity and acceleration vectors, so use this to help with the diagram. Remember the length of arrow indicate the relative size of the vector. Label all the vectors acting on a projectile at different stages of flight. Summarize your discoveries including explanations for the different flight paths.Ĥ. Use the simulation to investigate how the items you listed in #2 effect the shape of the flight path. Draw the flight path of your drink can and describe the shape. Compare your list with another group, discuss your explanations and make modificationsģ.Next to each item, briefly explain why you think the landing location changes.
