Product Description

Motion and force experiment device

Product Introduction
The instrument consists of three kinds of friction materials (cloth, sandpaper, rubber), including inclined panel (with support frame), flat panel (with baffle), transition plate, trolley, ball (one metal ball of 16mm and 20mm, one glass ball of 16mm), empty box, plastic chute plate, and three kinds of friction materials (cloth, sandpaper, rubber). The length of the flat panel is 800mm, and the width is 120mm.

Instructions
Installation of the instrument: lift the bracket behind the inclined panel to make the inclined panel and flat panel form a certain inclination. Insert a transparent transition piece at the junction between the inclined panel and the flat panel to make the inclined plane and horizontal plane have an arc transition. After installation, the following experiment can be carried out.

Experiment 1: Influence of Friction on Object Motion
(1) Lay three different kinds of friction materials on the flat plate (place the friction materials under the transition plastic sheet), place the trolley on the upper end of the inclined panel (the trolley slides from the same height), let the trolley slide from the end of the inclined panel to the static position, observe the trolley's running distance under different friction materials after sliding from the same height.

(2) Without any friction materials on the flat plate, place the trolley on the upper end of the inclined panel (the trolley slides down from the same height), and let the trolley slide from the static position at the end of the inclined panel. Observe the running distance of the trolley after the trolley slides down from the same height.

Conclusion: The smoother the plane plate is, the longer the distance the trolley moves, and the less the speed decreases, which indicates that the less friction the trolley is subjected to. Different trolleys of friction materials are subject to different friction forces, and the distance of trolley movement is different.

Guess: If the flat plate is absolutely smooth, if the car itself is not subject to any resistance and the speed will not slow down, the car will keep the same speed and move forever.

Experiment 2: The moving object has inertia
Place the baffle plate at an appropriate position on the flat plate, place an object (empty box) on the trolley, and let the trolley slide down from the slope. The trolley stops when it meets the baffle plate, while the object (empty box) on the trolley continues to slide forward due to inertia.

Experiment 3: Static objects have inertia
Place an object (empty box) on the trolley vertically, place the trolley on the flat plate, and suddenly push the trolley with force. It can be found that the object (empty box) on the trolley falls in the opposite direction, indicating that the stationary object has the inertia to remain stationary.

Through the above experiments, we can understand that: when all objects are not affected by external forces, the original static state will remain static; The original motion will maintain a uniform linear motion. This is Newton's first law. We call the property that an object keeps its state of motion unchanged inertia, and Newton's first law is also called the law of inertia.

Experiment 4: Moving objects have kinetic energy
Place the chute plate on the inclined panel, and place the empty box at 10-20 cm of the plane plate. Slide three balls of different sizes down the chute from the same height and different heights. If the ball strikes the hard box, the empty box will slide forward for a certain distance.
The greater the mass of the ball at the same height, the greater the sliding distance of the impacted empty box, and the greater the kinetic energy. Use the same ball to slide freely at different heights. The higher the height, the greater the sliding distance of the impacted empty box, and the greater the kinetic energy.
