Description of
Large-size wooden dynamic cart
Large-size wooden dynamic cart (C15-1631-W1) is designed to be used in combination with metallic
dynamic cart DY-5 (C15-1622-W0) for a variety of dynamics experiments. Additionally, the top of the
large-size wooden dynamic cart is spacious enough to load up to two metallic dynamic carts for a variety
of motion experiments.
Furthermore, it is easy to calculate and then analyze results of experiments because each cart of the
set (one wooden and two metallic carts) weighs 1kg. That enables simple calculation when substituting
the mass (m=1) to motion equation.
Experiment Guide
1. The law of inertia (Newton's first law)
Fig. 1
This is a simple experiment to demonstrate the inertia motion (Newton's first law) using the large
wooden cart and a metallic cart. Place a metallic cart on top of the large wooden cart and move the
large wooden cart to left and right swiftly by your hands. Learners will observe a metallic cart not mowing
while the large wooden cart is moving.
2. The law of conservation of momentum in collisions
(Newton’s third law)
