A juggler repeatedly throws two balls to the same height 3.0 m above the height of his hands. He times his throwing such that the balls are the same height when 1.0 m above his hands, with one ball going upwards and the other going downwards. At this position, 1.0 m above his hands: The accelerations of the balls are equal but the velocity of the ball going downwards is three times that of the ball going upwards O Their velocities of the balls are equal but the acceleration of the ball going upwards is three times that of the ball going downwards The velocities of the balls are equal but their accelerations are equal and opposite O The velocities and accelerations of the balls are equal The velocities and accelerations of the balls are both equal and opposite The accelerations of the balls are equal but their velocities are equal and opposite
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.
