A public transportation bus travels back and forth along a road, following the position versus time graph over the time period shown in the graph. There are five points labeled on the graph. Position (km) 60.0 55.0 50.0 45.0 40.0- 35.0 30.0- 25.0- 20.0- 15.0- 10.0- 5.0- 0.0 1 0.5 1.0 1.5 2.0 2.5 3.0 3.5 4.0 4.5 5.0 Time (h) What are the average speed and velocity (magnitude and direction) of the bus between point 1 and point 3? average speed₁_3 = m/s average velocity 1-3 = What is the average speed and velocity of the bus between point 3 and point 5? 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.
