Dynamics carts are used in studies of many different principles of physics including energy, forces, speed, velocity, acceleration, momentum, inertia and Newton’s Laws of motion. Energy is defined as the ability to do work. There are many types of energy including mechanical, electrical, sound, heat, light and chemical energy.
Many linear motion demonstrations can be performed with the dynamics track. The track may be set up with two electronic timers that measure the time it takes a 10 cm flag mounted on a cart to pass in front of an infrared sensor.
Dynamic track is defined as the total mechanical angular variation from facet to facet perpendicular to the scanning direction. This effect is illustrated in figure 1. An optical beam illuminating a polygon with a dynamic track of 10 arc seconds will have a scan envelope from all the facets of 20 arc seconds perpendicular to the scan direction.
Dynamic Track Collisions. Elastic and inelastic collisions between carts can be demonstrated as one end of the carts are equipped with magnets and the other end with Velcro. A moving cart collides elastically with a stationary cart of equal mass using the magnetic ends.
11 Φεβ 2001 · For this activity, a Smart Pulley will measure the motion of a cart as it is pulled by a string that is attached to an object suspended over the pulley. The Science Workshop program calculates the changing speed of the cart as it moves. A graph of speed and time can give the acceleration of the cart.
Dynamics Track, Carts with Friction Accessory, Air Track, Cars with Screens of Different Areas set at 90 Degrees to Direction of Travel, and Interface with Sensors. Procedure: The dynamics track can be either level of inclined for this demonstration.
