Conceptual - 2D Motion
Determine for each of the following statements whether it is true or false.
True: It is possible to be accelerating if you are traveling at a constant speed.
False: You are driving directly behind a pickup truck, going at the same speed as the truck. A crate falls from the bed of the truck to the road. Your car will hit the crate before the crate hits the road if you neither brake nor swerve.
False: If the elevation angle of a projectile at launch increases, its range decreases.
True: If the elevation angle of a projectile at launch increases, its time-of-flight until impact also increases.
True: In projectile motion when air resistance is negligible it is never necessary to consider 3D motion rather than 2D motion.
True: If the acceleration of a body is constant in a given inertial reference frame, it is constant in all other inertial reference frames.
True: It is possible to be accelerating if you are traveling at a constant speed.
