# Engage: Legend or Legendary?

These guys are pretty amazing. They perform different tricks in this video that may seem impossible. See for yourself. Are the shots real or fake?

Is it possible to do these shots again? Why or why not?

# Explore: Analyzing Projectiles

A projectile is any object moving through air or space wherein gravity is the only external force acting on it. Like the shots shown in the video in the Engage activity, the motion of a projectile seems to be complicated. However, if we look at the vertical and horizontal components of a projectile’s motion separately, we will find it very simple.

In this activity, you will use a simulation to analyze how the different variables affect the motion of  a projectile. Open and print the Analyzing the Motion of a Projectile activity sheet from the Related Documents section at the bottom of the page. Use the simulation below to complete the activity.

In your science notebook, explain why the vertical and horizontal motions of projectiles should be analyzed separately.

Before watching the second video, open and print Sample Projectile Calculation from the Related Documents section at the bottom of the page. Watch the video and use it as a guide to solve the sample problem.

Note: You may see variables represented differently depending on the source. For example, the following variables are used to represent vertical displacement and horizontal displacement in the video:

$dv$ =  vertical displacement                 $dh$  =  horizontal displacement

Since vertical motion is usually associated with the y-axis, and horizontal motion is usually associated with the x-axis, "y" and "x" are often used in relation to vertical and horizontal motion.

These variables are used to represent vertical displacement and horizontal displacement in the Sample Projectile Calculation document:

$dy$ =  vertical displacement                   $dx$ =  horizontal displacement

# Elaborate: Calculating Projectiles

Open and print the Calculating the Motion of a Projectile activity sheet from the Related Documents. Use the simulation to collect the data you need to complete the activity. Complete all the calculations on the activity sheet, and then turn in your paper to your teacher to check your answers.

# Teacher Notes

This resource is a collection of interactive materials, videos, and other digital media assembled in a conceptually scaffolded 5E lesson format. It provides alternative or additional Tier 1 learning options for students learning about projectile motion—Physics  TEKS (4)(C). The assignments require student participation with self-checked and teacher-checked formative assessment opportunities. For example, after students record observations and data in their notebooks, they may be prompted to be prepared to share their answers with the class.

Review the resource before assigning it to your students to check for prerequisite knowledge, differentiation needs, and student follow-up requirements as necessary. Students will need a science notebook or something on which to record their responses.
