86-实验 探究加速度与物体质量、物体受力的关系（86 - the relationship between the acceleration and the mass and the force of the object） The relationship between acceleration and object mass and force is studied Intelligent drilling field 1. In the experiment exploring the relationship between acceleration and object quality and object force, the following method is correct () A: when balancing the friction, the small dish should be fastened to the car by A fine line B. every time you change the quality of the car, you dont need to balance the friction C. In the experiment, first let go of the car and then switch on the power of the clock timer D. When the acceleration of the movement of the car can be measured, the weight of the small disk and the weight (M and M) and the vehicle quality can be measured in the balance So M is going to be equal to the formula a = g Answer: B 2. The explore the acceleration and the object quality, stress the relationship of experiment, after good equipment in accordance with the requirements of the experiment device, experiment should be according to certain steps, the following steps is endless and reasonable arrange order, please fill in the following order will be reasonable to letter iv: ____________________. A. maintain the quality of the small disk and the weight, add weight to the car, measure the acceleration, and repeat several times B. keep the car quality unchanged, change the quality of the small plate and weight, measure the acceleration, and repeat several times C. measure the quality of the trolley and the small pan with the balance D. Balance the friction, making the car approximate the uniform motion E. Put a small plate, put it in the weight, put it on the power of the clock timer, let go of the car, and put a series on the paper tape The point of F. According to the measured data, draw a - F and a - graph Answer: DCEABF or DCEBAF (3) (2010 · huaian simulation) in order to explore the relationship between the acceleration and force, usin
