# Motion

Arbor Scientific is providing physics and physical science teachers with a collection of student lab activities on the study of Motion. Here you can browse lab activities by title and get teachers notes, student worksheets and a list of equipment and supplies needed for each activity.

• ## Momentum - Tailgated by a Dart

Posted on February 10, 2012 by Arbor Scientific

In this lab, students will learn to estimate the speed of an object by applying conservation of momentum to an inelastic collision. Energy is not lost its transferred from one object to another. Students will fire a dart into the back of the free rolling car and measure the distance of the car, calculate the speed of the dart and car, and measure the mass of the car and dart.

• ## Tornado in a Bottle Inquiry

Posted on January 1, 2011 by Dr. Russell Harkay

We will use funnels, soda bottles, and a toy called a Tornado Tube to explore the concepts of moment of inertia, rotational motion, angular momentum, kinetic and potential energy, and air pressure in an attempt to discover and explain the physics of a rather complex hydrodynamic system.

• ## Range of a Horizontal Projectile

Posted on January 1, 2011 by Arbor Scientific

Students will use a photogate to measure the launch velocity of a horizontal projectile. That velocity will be used to predict the projectile’s range, or horizontal displacement. The Marble Projectile Ramp is used to launch a marble horizontally from a table or desk. The included screws can be moved to provide up to four different [...]

• ## Horizontal Projectile

Posted on January 1, 2011 by Buzz Putnam

Students will use a simple method, employing just a meter stick and stopwatch, to determine the initial velocity of a horizontal projectile. They will then predict the range of the projectile, precisely measure the actual range by using carbon paper, and calculate the percent difference.

• ## Acceleration and Gravity

Posted on January 1, 2011 by Arbor Scientific

When a car is on a ramp, a portion of its weight works to roll it down the ramp. Another portion works to hold it down to the ramp. These two portions, or component forces, are perpendicular to one another and can be found by using the car’s weight and the angle of the ramp.

• ## Racing Marbles: The Race

Posted on January 1, 2011 by Arbor Scientific

Two marbles will roll simultaneously on different paths, starting and ending at the same height. Students will predict and then observe the results of a “race” between the two marbles, and explain the results. Quantitative analysis of the motion will be done with photogates.

• ## Observing Acceleration with an Accelerometer

Posted on January 1, 2011 by Arbor Scientific

Use a liquid accelerometer to observe different types of motion and classify the acceleration. Students will observe straight-line motion (constant velocity and constant acceleration), and then take their knowledge of the water’s behavior to more complex circular and pendulum motion. They will discover the centripetal (toward the center) acceleration of circular motion, and the acceleration toward equilibrium of a pendulum system.

• ## Acceleration Due to Gravity

Posted on January 1, 2011 by Cary Busby

The first experiment will use very basic equipment to measure an important quantity, the acceleration of an object in freefall. This is also known as the acceleration due to gravity, or g. The acceleration due to gravity is nearly the same at all points on the earth’s surface, 9.8 m/s2. You will compare your result to this accepted value. The second experiment will use a data-logger and photogates to measure the acceleration due to gravity. The “picket fence” has been used since photogates were developed to measure acceleration. The “pickets” block the photogate in sequence, giving a series of velocity readings. Using the velocities and the times between those velocities, the data-logger (or the student) can calculate the acceleration of the picket fence. The third experiment will use a data-logger and motion sensor (or sonic ranger) to measure the acceleration due to gravity.

• ## Factors Affecting Frequency

Posted on January 1, 2011 by Arbor Scientific

Two experiments. Choose one. In the first, students are guided through the process of testing 3 variables; mass, length, and amplitude; to determine which affects the frequency of a simple pendulum. In the second, students use inquiry and experimental design to test the same variables.

• ## Graphing Pendulum Motion

Posted on January 1, 2011 by Arbor Scientific

Students predict and then measure, using a motion sensor, the changing position, velocity and acceleration of a simple pendulum. Graphing the motion leads to a discussion of the total force on the pendulum at different points in its motion.
