Which of the following are TRUE? Choose only three (3). Select one or more: a. At constant launch angle, maximum height decreases as initial velocity increases. The maximum height is inversely proportional to the square of the initial velocity. b. At constant launch angle, range increases as initial velocity increases. The range is directly proportional to the square of the initial velocity. c. At constant launch angle, maximum height increases as initial velocity increases. The maximum height is directly proportional to the square of the initial velocity. d. At constant launch angle, range decreases as initial velocity increases. The range is inversely proportional to the square of the initial velocity. e. The time of flight is directly proportional to the initial velocity. At constant launch angle, time of flight increases as initial velocity increases. f. The time of flight is inversely proportional to the initial velocity. At constant launch angle, time of flight decreases as initial velocity increases.
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.
