Horizontally Launched Projectiles

We enlist a high school baseball team to help show how objects behave when they travel as horizontally launched projectiles.

Unit 2 Segment G: Horizontally Launched Projectiles We enlist a high school baseball team to help show how objects behave when they travel as horizontally launched projectiles.

Premiere Date: August 2, 2018 | Runtime: 00:09:33

## Learning Objectives

-Define key terms related to projectile motion such as projectile, trajectory, range, and hang time.

-Explore why we analyze the motion of a projectile separately in the horizontal and vertical directions.

-Analyze the horizontal and vertical components of motion separately by doing an example.

-Reinforce the idea that elapsed time is the same for an object at its given position in the vertical direction and the horizontal direction.

## Vocabulary

hang time - the amount of time a projectile remains in the air.

projectile - an object that is moving through the air.

range - the displacement of a projectile in the horizontal direction.

trajectory - the path taken through the air.

## Georgia Standards of Excellence

SP1
Obtain, evaluate, and communicate information about the relationship between distance, displacement, speed, velocity, and acceleration as functions of time.
d
Analyze and interpret data of two-dimensional motion with constant acceleration. • Resolve position, velocity, or acceleration vectors into components (x and y, horizontal and vertical). • Add vectors graphically and mathematically by adding components. • Interpret problems to show that objects moving in two dimensions have independent motions along each coordinate axis. • Design an experiment to investigate the projectile motion of an object by collecting and analyzing data using kinematic equations. • Predict and describe how changes to initial conditions affect the resulting motion. • Calculate range and time in the air for a horizontally launched projectile.

## Request Teacher Toolkit

The Physics in Motion teacher toolkit provides instructions and answer keys for study questions, practice problems, labs for all seven units of study.  GPB offers the teacher toolkit at no cost to Georgia educators. It will be available in September 2018. To preorder your teacher toolkit, complete and submit this form to request the teacher toolkit. You only need to submit this form one time to get materials for all seven units of study.
