高一物理必修二知识点复习提纲(国外英文资料) Brambling yasutomo lofty ambition is. Born in misery, died in peace. Take things as they come. Difficult to find, do not come around. Tidal flat across the river, the wind is capable of hanging. Knowledge points of projectile motion First, the characteristics and laws of uniform and variable rectilinear motion: ? uniform variable rectilinear motion: acceleration is a constant, and speed in a straight line. Basic formula:,, (applied only to uniform, variable, linear motion). * when v0=0 and a=g (free fall motion) have... Vt=gt,,,. When the vertical, V0? A= -g (vertical projectile motion). Note: (1) the rising process is uniform deceleration linear motion, and the falling process is uniformly accelerated linear motion. (2) the acceleration of the whole process is g, the direction is vertical and downward, and the whole process is a uniformly variable linear motion (3) the time from the throw to the drop back point: T = 2V0/g, =2, t, =2, t (4) maximum height of rise (relative throw point): H=v02/2g (5) the acceleration is the same as the acceleration at the same position, but the velocity is equivalent to the reverse (6) the time of rising and falling is the same as that of the same displacement. (7) the whole method is used to solve the problem: take the vertical upward direction as the positive direction, and the S0 indicates that the position of the particle is at the top of the throwing point. S0 indicates that the particle position is below the throw point. The VT 0 indicates the direction upwards; the VT 0 indicates the direction down. At the highest point, a=-g v=0. Two, the synthesis and decomposition of motion: 1. two uniform linear motion object motion is ___________________ movement. In general, the two linear motion of the motion is not ____________ movement, may also be _____________ movement. Hi, and the movement time is __________. 2. because of displacement velocity and acceleration are ______, their synthesis and decomposition ar
