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.
I need help with questions 1-4, and I know they are multiple parts but they count as one question.
There are two different graphs. First graph is complete and in second graph the y axis is missing.
Considering the first graph the questions are answered.
1.
First let us understand few point about displacement vs time graph.
The time is indicated along the horizontal direction and displacement is indicated along vertical direction.
A straight line horizontal line in displacement vs time graph denotes no motion of the object.
A straight line with uniform slope represent a uniform velocity of the object. It the slope is positive the velocity is positive and if the slope is negative then the velocity is negative.
A curved line indicates the object is accelerating. If the positive slope of the curve is increasing then the object is having positive acceleration and if the positive slope of the curve is decreasing the object has negative acceleration
