| Abstract: | In this paper, we discuss how to use a microcomputer to demonstrate the various properties of a projectile.First, when we neglect the resistance of the air, several meaningful curves are obtainted. These curves are the circles of the distribution of the projectiles, the safty parabola, the ellipse of the top points, and so on.Then, we take into account the resistance of the air. And take it as an exam ple, we introduce a method of solving physical problems by means of the microcomputer, especially for those problems in which the body are exerted by variable forces, or the body's mass is variable. |
