在近几年的中考物理命题中,以汽车为载体的计算题占有一定的数量,这类习题有浓厚的生活气息, 拉近了物理与生活的距离,提高了学生学习物理的兴趣,现归纳整理如下,以便共同探讨。一、声、运动类计算例1 一辆汽车以20米／秒的速度驶向一座山崖,司机在某处按喇叭,4秒后听到回声,求汽车按喇叭处离山崖多远? In the physics propositions of the middle school exams in recent years, the computational problems involving cars as a carrier occupy a certain amount. Such exercises have a strong atmosphere of life, which narrows the distance between physics and life and improves students’ interest in learning physics. Organize as follows in order to discuss together. First, sound and sports calculation example 1 A car driving at a speed of 20 meters / second to a cliff, the driver horn in some place, after 4 seconds to hear the echo, seeking car horn from the cliff how far away?
