A super ball dropped from rest falls 2 meters vertically downward and rebounds 2 meters upward in a total time of 1.6 seconds. Just as it arrives at its initial starting point, what are the magnitude of the average velocity and the average speed, respectively? 0 m/s and 1.3 m/s zero and 2.5 m/s 2.5 m/s and 2.5 m/s 2.5 m/s and zero 1.3 m/s and 1.3 m/s
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.
6. A super ball dropped from rest falls 2 meters vertically downward and rebounds 2 meters upward in a total time of 1.6 seconds. Just as it arrives at its initial starting point, what are the magnitude of the average velocity and the average speed, respectively?
0 m/s and 1.3 m/s
zero and 2.5 m/s
2.5 m/s and 2.5 m/s
2.5 m/s and zero
1.3 m/s and 1.3 m/s
The ratio of the total distance to the total time taken is the average speed.
The ratio of the total displacement to the total time taken is the average velocity.
