Down: 1) the unbalanced force that causes objects to move ina circular path is called a_______2) newtons _________states that a moving object that is not acted on by an unbalanced force will remain in motion3) an object in motion stays in motion because it has___________5) motion that is parallel to the ground6) terminal velocity is acheived when the net force on a falling objects is ________8) newtons 3rd law states that when ever one object exerts a force on a second object the second object exerts an ___ ___ __________ force on the first object10) this states that when 2 objects interact they may exchange momentum12) objects accelerate toward the eath at 9.8m/s/s. this means that for every second that an object falls, its downward velocity ____by 9.8m/s15) the path that a thrown object follows17) this occurs because air particles have mass and inertia that resists movement18) falling objects stop accelerating at this19) newton had three of these20) orbiting objects appear to be wheightless because they are in____ _____25) air resistance is ____friction27) these dont act on the same object29) these were used as weapons in the middle ages that had projectile motion Across: 4) the path that a thrown object follows7) the amount of air resistance acting on an object depends on the objects ____ _______ _________9) this provides the centripetal force that keeps objects in the moon11) an orbit is formed by combining a ___ motion and free fall toward the earth13) Galileo proved that the rate at which an object falls is not affected by the___14) a property of moving objects that depends on mass and velocity is________16) projectile motion has both a _________ ____ _____component21) terminal velocity is acheived when the net force on a falling objects is ________22) parachutes slow skydivers to a safer terminal velocity because parachutes __________ air resistance23) if a feather and a rock dropped at the same time, when dropped____24) traveling in a circular path around another object26) an object in motion stays in motion because it has___________28) free fall occurs in a____ or in space30) motion that is perpindicular to the ground31) air resistance causes this to stop at terminal velocity32) terminal velocity occurs when the force of air resistance matches the ____force of gravity
