![]() How does the range vary with launch speed? It is a linear relationship? Maximizing the range – You may want to hit the magnifying glass with the minus sign in it, a couple of times, to zoom out a little for this part. ![]() Fill out the table and make a plot: vi (m/s) (plot on x- axis) Range (m) (plot on y- axis) 0 Were you correct in your prediction? Explain. Find the range for several different values of initial speed (make sure you get values over the whole range of initial speeds available). Predict: What will happen to the range when you double the velocity? Range versus initial speed: Experiment 1: How does the initial speed affect the range of the projectile? Set the angle to 60 degrees. Boston University Studio Physics – Phet Projectile Motion Exploration page 2 For the rest of the lab, have the simulation in “Lab” mode. It’s a good idea for each member of the group to do a calculation (maybe even different ways) so you can double-check your method. Then verify the value the simulation is using for g. Describe your strategy here, detailing the steps: Compare strategies with the other students in your group. Note that the simulation has a helpful blue measurement tool which, when placed on one of the dots, tells you the time, horizontal position, and vertical position for that point on the trajectory. Come up with a strategy to verify what value the simulation is using for g. Finding g: Use these settings - an angle of 60° and an initial speed of 18 m/s. Choose your favorite projectile…does it matter which one you choose? Now draw a diagram of the situation in the box to the right, labeling all relevant quantities. Click-and-drag on the target to move it horizontally to the impact point on the ground. Spend 5 minutes just playing with the simulation to see what it can do. ![]() _13 _ m/sanday-velocity comporient of _ 7.5 _ m/s.Download Phet Projectile Motion Exploration page 1 and more Physics Lecture notes in PDF only on Docsity!Boston University Studio Physics – Phet Projectile Motion Exploration page 1 Name:_ Group: _ Section:_ Lab 2: Phet Simulation – Projectile Motion Phet simulations are simulations on all sorts of topics (not just physics) that come from the University of Colorado - Boulder To find the simulation, either Google “Phet simulation projectile motion” or go directly to this link: Click “Intro.” When the simulation opens, hit the “Fire” button. ![]() of 15 m/s would | have an x- velocity component of So, the projectile would fire as far as one fred horizontally at 8.5 m/s and as high as one firedĪ projectile fired at 30 degrees with a velocity. The projectile would have a y-velocity of |v, = 20sin 65] or 18 m/s. So, a projectile fired at 20 m/s at 65° has an x-velocity of |v, = 20 cos 65] or 8.5 m/s. Magnitude of the velocity by the sine of the angle, 0. “* Similarity, the y-component of velocity is found by multiplying the The velocity by the cosine of the angle, 0. The x-component (v,) is found by multiplying the magnitude of Attempt to hit the target with three different angles by changingĪ projectile’s velocity (v) has an x-component (v,) and a y-component «Measure the distance from the cannon to the target using the tape measure.Į Move the target to 21.0 m from the cannon. ° Set the initial speed to a value between 10-15 m/s. ¢ The cannon can be moved to add or remove initial Y position and X position.Į The cannon can be pivoted to change the firing angle, 9.Į The tape measure can be moved and dragged to measure range to target.īe sure air resistance is off and spend some time firing various projectiles. That while gravity (acceleration) acts on the projectile in the verttea\ direction, itĭoes not affect the velocity of the projectile in the _\ovizwwtal direction. In this:module, you will investigate the motion of a simple projectile: Realize In the Y direction is independent of the acceleration (if any) and velocity in the Xĭirection. Projectiles travel with two components of motion, X any Y.
