Cards Term Trajectory Definition the path of a projectile Term lever arm Definition the perpendicular distance from the axis of rotation to a line along which a force acts Term equilibrant Definition a force that produces equilibrium Term range Definition the horizontal distance traveled by a projectile Term centripetal force Definition a force that acts toward the center of a circle Term maximum height Definition the height of a projectile when its vertical velocity is zero Term rigid rotating object Definition a mass that rotates around its own axis Term flight time Definition the time a projectile is in the air Term centripetal acceleration Definition acceleration toward the center of a circle Term projectile Definition an object that has been launched by an initial thrust Term normal force Definition a contact force that acts perpendicular to an away from a surface Term torque Definition the product of a force and the lever arm Term uniform circular motion Definition the movement of an object or a point mass at constant speed around a circle with a fixed radius Term equilibrium Definition when the net sum of the forces acting on an object is zero Term coefficient of kinetic friction Definition the ratio of the force of kinetic friction to the normal force Term period Definition the time needed to complete one cycle of motion
