Model Description This training aid demonstrates the translational and rotational kinematics of a rigid body in a non-rotational frame. This demonstration should take 10-15 minutes. Engineering Principle Building upon the concept of Rotation About a Fixed Axis (RAFA), the helicopter provides an excellent example to step into general planar motion (GPM) by first demonstrating the […]
Model Description This training aid demonstrates the kinematics of multiple connected rigid bodies in translation, rotation, or general planar motion. This demonstration should take 10-15 minutes. Engineering Principle This training aid demonstrates the kinematics of a multi-body structure. Motion for each part of the structure is classified and discussed. A KNEX motor brings the training […]
Model Description This training aid demonstrates the translational and rotational kinematics of a rigid body in a translating and rotational frame. This demonstration should take 30 minutes. Engineering Principle Building upon general planar motion (GPM) in a non-rotational frame, this model develops the need to address GPM in a rotational frame by examining a projectile […]
Model Description This is a simple demonstration of the basic principles and behavior underlying projectile motion. A Nerf gun is used to show that projectile motion can be modeled by a particle having a vertical component of motion with constant acceleration, and a horizontal component with constant velocity (zero acceleration). This demonstration should take 5-8 […]
This training aid demonstrates the translational and rotational kinematics of rigid bodies in translating as well as translating and rotating reference frames. This demonstration should take 15 minutes
This is a simple demonstration to distinguish among a particle’s coordinates, position, displacement, and total distance traveled. A remote-controlled car is used to demonstrate the distinctions, for a particle in rectilinear motion. This demonstration should take 5-8 minutes.
This training aid demonstrates the rotational kinematics of a rigid body, the first step in rigid body kinematics problems.
This demonstration should take 10-15 minutes.
