Source: Andrew Duffy, PhD, Department of Physics, Boston University, Boston, MA This experiment examines at various situations involving two interacting objects. First, the experiment examines the forces that two objects apply to one another while they collide. The objects are wheeled carts that have variable masses. The purpose of this experiment is to discover when the force the first cart exerts on the other is the same magnitude as the force the second cart exerts back on the first, as well...

Source: Tamara M. Powers, Department of Chemistry, Texas A&M University The glovebox provides a straightforward means to handle air- and moisture-sensitive solids and liquids. The glovebox is what it sounds like: a box with gloves attached to one or more sides, which allows the user to perform manipulations within the glovebox under an inert atmosphere. For manipulations under inert atmospheres, chemists can choose between Schlenk or high-vacuum techniques and a glovebox. Schlenk and...

Source: Ella M. Atkins, Department of Aerospace Engineering, University of Michigan, Ann Arbor, MI Overview Autopilot allows aircraft to be stabilized using data collected from onboard sensors that measure the aircraft’s orientation, angular velocity, and airspeed. These quantities can be adjusted by the autopilot so that the aircraft automatically follows a flight plan from launch (takeoff) through recovery (landing). Similar sensor data is collected to control all types of aircraft, from...

This lab will begin by studying motion in 1 dimension, under constant acceleration, by launching a projectile directly upward and measuring the maximum height reached. This lab will verify that the maximum height reached is consistent with the kinematic...
FAQs
The sensing mechanism determines what physical change becomes measurable. Infrared designs respond to changes in infrared radiation, whereas systems using reflected sound or electromagnetic waves interpret changes in returned signals. Accelerometer-based devices instead generate data from acceleration. These alternatives allow motion to be measured through different signal types, while the shared output is electrical data suitable for behavioral analysis.
An accelerometer is especially relevant when the measurement depends on movement or acceleration associated with the subject. Its signals can support estimates of activity or locomotion without requiring an observer to continuously watch behavior. This makes the recorded pattern useful for comparing activity levels or responses to environmental conditions, provided the selected sensor captures the behavior of interest.
Continuous monitoring changes the type of behavioral evidence available. Rather than relying only on intermittent observations, investigators can quantify activity over an extended period and examine locomotion, exploration, or responses to environmental conditions. The resulting measurements are objective and can reduce observer bias, which is valuable when behavior varies over time or occurs outside direct observation.
Motion Sensor data can be used to quantify locomotion, general activity levels, exploration, and responses to environmental conditions. These measures translate movement-related signals into behavioral variables that can support studies across different conditions. The value lies in converting observed changes into measurable activity patterns, rather than depending solely on descriptive judgments by an observer.
The same general approach supports work with both humans and animals and is useful in laboratory, clinical, and field settings. In laboratory studies, it can quantify activity during behavioral experiments; in clinical contexts, it can support activity measurement; and in field research, it enables monitoring where continuous direct observation is impractical.
Selecting among infrared, reflected-signal, and accelerometer-based designs depends on which motion-related change needs to be captured. A system based on infrared radiation, reflected sound or electromagnetic waves, or acceleration will produce data from a different physical signal. Matching that signal to the behavioral question helps investigators measure the intended activity, locomotion, exploration, or environmental response.
