Four Wheel Dynamic Cart
Model Number: MTM-71
The Four Wheel Dynamic Cart from Micro Technologies is a low-friction mechanics laboratory cart designed for experiments involving motion, velocity, acceleration, momentum, force and collisions. It features four ball-bearing wheels, a spring bumper and space for carrying five steel bars to vary the cart mass. Each cart is supplied with one heavy and one light bumper spring, allowing different collision conditions to be investigated.
Product Specification
The Four Wheel Dynamic Cart from Micro Technologies is a versatile mechanics laboratory apparatus developed for practical experiments involving linear motion, force, acceleration, momentum, inertia and collision dynamics.
The cart is equipped with four low-friction ball-bearing wheels designed to provide smooth movement along a suitable laboratory track or level surface.
Reducing rolling resistance is important in mechanics experiments because it minimizes the influence of unwanted external forces and allows the observed motion to more closely represent theoretical conditions.
The cart includes space for carrying five ordinary steel bars, enabling students to vary the total mass of the moving system.
By adding or removing steel bars, different mass configurations can be created for experiments involving force, mass and acceleration.
Newton’s Second Law can be represented as:
F = ma
where:
F = Net Applied Force
m = Mass of Cart System
a = Acceleration
Students can use the cart to observe how increasing mass influences acceleration when the applied force remains approximately constant.
The ability to change the cart mass is also useful for momentum and collision experiments.
Momentum is expressed as:
p = mv
where:
p = Momentum
m = Mass
v = Velocity
By using two compatible carts with different mass configurations, students can compare their motion before and after a collision and investigate the principle of conservation of linear momentum.
A key feature of the Four Wheel Dynamic Cart is its spring bumper arrangement.
Each cart is supplied with one heavy spring and one light spring, allowing students to compare collision behavior under different spring conditions.
The bumper springs help provide controlled interaction between carts during collision experiments and can be used to explore concepts associated with elastic collisions, impulse and energy transfer.
The cart can also be used for experiments involving inertia and Newton’s First Law of Motion.
When external resistance is minimized, students can observe how the cart tends to maintain its motion until acted upon by an external force.
Depending on the complete laboratory setup, the Four Wheel Dynamic Cart may be combined with inclined planes, pulleys, cords, masses, timers or motion-measurement equipment for a broader range of dynamics investigations.
According to the supplied catalog specification, each cart measures approximately 7.5 × 25 cm, excluding the wheels and bumper spring.
The compact construction and low-friction wheel system make the cart suitable for repeated quantitative and qualitative mechanics experiments.
Instructions are supplied to assist with experimental setup and use.
Manufactured and supplied by Micro Technologies, the Four Wheel Dynamic Cart is suitable for physics and mechanics laboratories requiring a reusable low-friction cart for motion and collision studies.
