Concept explainers

Displacement, Velocity and Acceleration

In classical mechanics, kinematics deals with the motion of a particle. It deals only with the position, velocity, acceleration, and displacement of a particle. It has no concern about the source of motion.

Linear Displacement

The term "displacement" refers to when something shifts away from its original "location," and "linear" refers to a straight line. As a result, “Linear Displacement” can be described as the movement of an object in a straight line along a single axis, for example, from side to side or up and down. Non-contact sensors such as LVDTs and other linear location sensors can calculate linear displacement. Non-contact sensors such as LVDTs and other linear location sensors can calculate linear displacement. Linear displacement is usually measured in millimeters or inches and may be positive or negative.

Your nephew got a Nerf Bazooka gun for Christmas, so you take it outside to play with it (just like my uncles did when I was little). The bazooka is on your shoulder, 1.5 m above the ground. You aim the gun 25° above the horizontal and the big, foam projectile leaves the gun with an initial velocity of 36 m You accidentally aim the bazooka at a tree that is a horizontal distance of 27 m away. How long does it take for the projectile to hit the tree? t = How high (above the ground) in the tree does the projectile get stuck? hfinal = m Imagine you were more clever and aimed into an empty field with no obstructions. You can control how fast the projectile leaves the gun by pumping more times or fewer times (more pumps = faster projectile). What are TWO ways you could increase the amount of time that the projectile is in the air?
