## Projectile motion activity

Horizontal projectile motion is one of the most basic examples of classical physics.

Gravity is a force that causes acceleration towards the center of the Earth at 9. This causes objects that are falling to increase in speed until they reach their terminalor maximum, velocity or until they are stopped by another force, like hitting the ground.

Horizontal motion, however, is a good example of Newtonian physics: things in motion stay in motion unless acted upon by another force. If an object is traveling horizontally, it tends to travel horizontally at the same speed until another force changes its motion. In this experiment, you will build a ramp and use that to project a ball off the table.

You'll calculate the ball's velocity to determine how far the ball will travel, allowing you to anticipate the ball's trajectory and place your target in the perfect spot. Where t is time, h is height, and g is gravitational acceleration, or 9. Because the ball does not travel very far, the horizontal velocity loss due to friction will be very small.

The horizontal space below the ramp is crucial to the experiment because it ensures that the vertical component of the ball velocity is zero when the ball leaves the table. This allows us to calculate the time it will take to hit the floor using only the height of the table and the acceleration due to gravity.

The vector nature of velocity and acceleration can be depicted on the screen. The animation can be started, paused, continued, single-stepped or rewound.

And finally, the time of flight, the horizontal displacement, and height are displayed during the course of the animation. Section 1: For Horizontally Launched Projectiles : Raise the launch height to about 50 meters and adjust the launch angle to 0 degrees.

Conduct several trials to answer the following questions. During the course of a trajectory, is the horizontal component of the velocity a constant or a changing value? During the course of a trajectory, is the vertical component of the velocity a constant or a changing value?

### Exploring Projectile Motion

Describe the acceleration of a projectile - direction, constant or changing magnitude, etc. Be complete. As a projectile falls vertically, it also travels horizontally.

Is the distance which it falls vertically effected by its horizontal velocity? Discuss how your data provide support for your answer. A classic mind-bender: If a ball is dropped from rest from an elevated position at the same instant that a second ball is launched horizontally from the same heightthen which ball will hit the ground first? Assume the balls behave as projectiles.

Consider questions in the previous section of this lab horizontally launched projectiles. Would launching a projectile at an angle effect any of the answers which you provided earlier?

Consider path or trajectory, horizontal velocity v xvertical velocity v y and acceleration. Be thorough and organized as you answer your questions.

At what point in the projectile's trajectory is the velocity vector entirely horizontal i. Pick a launch speed and angle and compare the time required for the projectile to rise to the peak of its trajectory to the time for the projectile to fall from the peak of its trajectory. The Single Step button and the Vector display can be used to assist in your measurements.

Repeat for other launch angles if necessary. Describe your findings. For a fixed launch velocity, what launch angle between 0 and 80 degrees maximizes the time of flight for an angle launched projectile? In the space below, display some collected data which clearly support your answer. Fill in the table below to investigate the effect of launch angle on horizontal displacement.

Based on the data collected above, which launch angle provides the maximum range horizontal displacement for a projectile? Describe any other obvious observations which you could make from the inspection of the above data.

Discuss the motion of a projectile in terms of the changes or lack of changes in its horizontal and vertical motion parameters. Comment on such quantities as horizontal velocity v xvertical velocity v yhorizontal acceleration a xand vertical acceleration a y. Do a bang-up job! Kinematics Newton's Laws Vectors and Projectiles.

The expendable cost is the estimated cost of supplies needed for each group of students involved in the activity. Understanding and predicting projectile motion, as illustrated by the path of the water, is critical to many engineering designs.

Understanding projectile motion is important to many engineering designs.

## Phet Projectile Motion Lab: Lab Answers

Any engineered design that includes a projectile, an object in motion close to the Earth's surface subject to gravitational acceleration, requires an understanding of the physics involved in projectile motion. This includes machines such as motocross bikes made for launching off jumps to weapons such as missiles, turrets and high-powered cannons.

NASA engineers apply projectile motion concepts as they predict the paths of meteorites that may enter the Earth's atmosphere or disrupt satellite transmissions. The combination of a physical understanding of projectile motion and the mathematical ability to solve equations enables engineers as well as young students to predict projectile trajectories.

Each TeachEngineering lesson or activity is correlated to one or more K science, technology, engineering or math STEM educational standards. In the ASN, standards are hierarchically structured: first by source; e. Develop and use models to illustrate that energy at the macroscopic scale can be accounted for as either motions of particles or energy stored in fields. Grades 9 - Do you agree with this alignment?

Students will predict which object will hit the ground first if set in motion at the same time. Your Account. Summary In this physics lab student will investigate how gravity affects an object that falls from a resting state and how it affects an object that is projected out from the same resting state.

Concept: Gravity affects all objects at the same rate. Students will set 2 objects in motion at the same time. One from a state of rest and a second that is projected outward from the same level at the same time.

Student will use observation to determine which will object hits the ground first. Vocabulary: gravity, acceleration, projectile motion. This is a mini lab that takes about 5 minutes. Equipment needed are 1 ruler, two flat objects coins, washers, discs This activity is used after discussing the concept of gravity and acceleration. This activity is very straight forward and does not need to be adapted.

Place a ruler on a desk with one edge hanging 3- 4 inches over the edge desk. Place one object on the ruler and the other next to the ruler and the edge of the table. Quickly move the ruler to strike the object on the desk. Prior to conducting the activity have students predict which object will hit the floor first.

## Projectile Motion Activity

This activity can be done as a class demonstration or in small groups. Space is needed to conduct this activity. Larger objects are easier to see.

Also if you conduct this activity on a tile floor students can hear the object fall and determine which object hits the floor first.This lab will answer whether or not initial speed affects the time that a projectile is in the air.

Also, it will be determined if there is a direct relationship or not between initial speed and time. According to the graph and results in the table, we see that the height of the projectile is consistently This coincides with the consistent measure of time of 1. Therefore, the height, a vertical component of the projectile, is directly related to the time, and the initial speed is not related at all.

Since it was discussed that the time was affected by vertical information such as height, we also know that the vertical acceleration of all freefalling objects is The lab fulfilled its purpose well because it displayed that various speeds do not affect the time it takes for a projectile to reach the ground. The initial speed and the time have no relationship whatsoever. Only vertical motion affects the time for a projectile. Article last reviewed: St.
