Composition: double-layer aluminum alloy guide rail, two trolleys, rubber feet, parallel adjustment brackets, track panels, pulleys, plastic bucketsDescription:1. Adjust the adjusting screw on the back of the base so that the track is parallel to the horizontal plane (check the bubble height).2. Add a certain amount of sand to the plastic bucket to balance the friction of the cart (the sand is added to the cart to move it at a constant speed).3, so that the quality of the car 2 is twice the mass of the car 1 (400 g), adding some sand to the plastic bucket to balance the friction of the car.Precautions1. During the experiment, the plastic bucket and the weight itself are also moving. The pulling force of the rope on the trolley is not equal to the weight of the heavy object. The weight of the sample is small and the weight of the rope is. It can be considered that the pulling force of the trolley is similar to the weight of gravity.2. Keep the tanker lubricated and refuel frequently.

• * Experiments show that the magnitude of the acceleration of the object is proportional to the force, inversely proportional to the mass of the object, and proportional to the reciprocal of the mass of the object; the direction of the acceleration is the same as the direction of the force.
• * Through the image experiment, help students understand the relationship between acceleration and quality
• * layer aluminum alloy track
• * It is also a good helper for parents to help their children improve their physics learning interest.
