Select the statements (facts/concepts) that comprise this learning goal.
Selected Statement Details:
IndepMotions The component of an object's velocity along an axis is not affected by a component of acceleration along a perpendicular axis.
KinEqn3_dv_plus_at^2 One-dimensional motion with constant acceleration is described by the equation $x_2=x_1 + v_1 (t_2-t_1)+\frac{1}{2} a (t_2-t_1)^2$, where $x_2$ is the position at time $t_2$, $x_1$ is the position at time $t_1$, $v_1$ is the velocity at time $t_1$, and $a$ is the acceleration.
ProjectileMotion Projectile motion is motion under the influence of only Earth's gravitational acceleration $g$, which is assumed constant in magnitude and direction. This means that the motion must be near Earth's surface, over distances that are small relative to Earth's radius, and air resistance and other forces are assumed to be negligible.
