ball is dropped from the top of a 70m tall building. You are about to catch it from the ground, what is the velocity of the ball, when it reaches your hand 2m from the ground? Do you think you catch it with this velocity, why or why Not? 2. Compare the maximum height reached by the two balls thrown from the ground in different directions. The first ball (Ball A) was thrown vertically upward straight to the air with a velocity of 2m/s. While the second was thrown sideways with an angle of 70o with initial velocity of 2m/s. Which ball will reach the higher altitude? Explain your answer.
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.
