| Velocity and Acceleration Suppose you throw a ball straight up into the air. Describe the changes in the velocity of the ball. Describe the changes in the acceleration of the ball. A weather balloon is floating at a constant height above Earth when it releases a pack of instruments. a. If the pack hits the ground with a downward velocity of 73.5 m/s, how far did the pack fall? b. Calculate the distance the ball has rolled at the end of 2.2 s. An object dropped from the top of a cliff. It is seen to hit the ground below after 5 seconds. Determine its velocity just before hitting the ground, Ignore air resitance.
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.
