Document Summary
Projectile motion (10. 1) gravity curves it velocity when air resistance is small enough to ignore. Without gravity, a rock tossed skyward at an angle would follow a straight line path, but. The horizontal component of velocity is independent of the vertical component of. The constant horizontal velocity component is not affected by the vertical force of gravity. This is because there"s no gravity acting on it. Objects travel the same horizontal distance in equal time intervals. When there"s a combination of horizontal and vertical motion, the ball"s path is curved. Projectiles launched at an angle no gravity. Vertical component is zero at top of trajectory. When air resistance is small enough to be ignored, a projectile will rise to its maximum height in the same time it takes to fall from that height to its initial level everywhere. Speed of satellite must be great enough to ensure that its falling distance matches earth"s curvature.
