![]() Investigate the variables that affect the drag force.ĭescribe the the effect that the drag force has on the velocity and acceleration.ĭiscuss projectile motion using common vocabulary (such as: launch angle, initial speed, initial height, range, time). Predict how varying the initial conditions will affect a projectile’s path, and provide an explanation for the prediction.Įstimate where an object will land, given its initial conditions.ĭetermine that the x and y motion of a projectile are independent. Blast a car out of a cannon, and challenge yourself to hit a target Learn about projectile motion by firing various objects. In addition, find the relation between the time of flight and the initial velocity, and find the time of flight equation. Explore vector representations, and add air resistance to investigate the factors that influence drag.ĭetermine how each parameter (initial height, initial angle, initial speed, mass, diameter, and altitude) affects the trajectory of an object, with and without air resistance. In this experiment, the experimenter will be able to identify projectile motion definition and use Phet simulation ( projectile motion)to be clear how the experiment is work. Set parameters such as angle, initial speed, and mass. ![]() _13 _ m/sanday-velocity comporient of _ 7.5 _ m/s.Blast a car out of a cannon, and challenge yourself to hit a target! Learn about projectile motion by firing various objects. 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. from publication: A comparison of two methods of active learning in. So, a projectile fired at 20 m/s at 65° has an x-velocity of |v, = 20 cos 65] or 8.5 m/s. Download scientific diagram Interface of the PhET Projectile Motion simulation. Magnitude of the velocity by the sine of the angle, 0. “* Similarity, the y-component of velocity is found by multiplying the By manipulating angle, initial speed, mass, and air resistance, concepts of projectile motion come to light in a fun and game-like environment. The velocity by the cosine of the angle, 0. 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 validation survey is composed of 20 que stions and divided into three categories. The x-component (v,) is found by multiplying the magnitude of features of the PhET as an instructional materia l in teaching Projectile Motion to Grade 9 students. 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.

NEW The Physics Classroom 2009 Answer Key Describing Motion Verbally. ° 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.
