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.
1: If a ball moves 5 meter in 0.5 second, what is its speed? Does it have velocity? Why?
2: Is 'Gravity' a scalar or vector quantity? Why?
3: Usain Bolt is running at a speed of 10 m/s to the north and you are running at 7 m/s to the south. What is Usain Bolt’s speed with respect to you?
4: Distance between city ‘A’ and city ‘B’ is 120 miles. Jacob starts his journey from city ‘A’ at 11:00 am and arrives at ‘B’ at 1:00 pm. What is Jacob’s average velocity? Express your result in feet/sec also.
