# Physics : Projectile Motion

Projectile MotionName:Group Members (if any):Instructions:Go to
the phet website for Projectile motionAll materials are from this
site. Click on the Lab box.All objects in free fall are affected by
gravity here on Earth. Objects moving in two dimensions such as a
punted footbaare no exception. These objects are affected by
gravity. Everything we throw, toss, kick, or shoot is called a
projectile.These objects all take the same path as long as we
ignore air resistance. This exercise lets you see what happens
wheyou vary launch angle, launch speed, and air
resistance.Outcomes:1. The student will describe the effects of
changing the launch angle on the range of the projectile.2. The
student will describe the effects of changing the launch speed on
the range of the projectile.3. The student will describe the
effects of air resistance on the range.Materials:N/ASafety
Points:N/AProcedure:*Note: You can choose what you want to launch,
but if it goes off the screen you will have to choose something
else. TPart A – Effect of launch on angle on projectile rangeMake
sure air resistance is not checked. Move the target out of the way.
Set the launch velocity at 10 m/s. Starting at 30 degreeData Table
