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.
![tells us how fast an object is moving and in what direction. But what if the velocity is changing? This is what
acceleration describes-how quickly the velocity of an object is changing In this activity we will learn about

Section 1
Introduction, To answer the question How do things move? we can provide the velocity of a Oojecwhat
when an object is accelerating and how to calculate the rate of acceleration.
Examples of Acceleration:
The following motions describe objects that are NOT accelerating
A bird flies at a constant speed of 10 m/s in a constant direction of North
A train travels at a constant velocity of 45 mi/hr South
A car travels along a straight section of highway at a constant 100 km/hr
The following motion describes objects that ARE accelerating
A bird, flying at a speed of 5 m/s, speeds up to 10 m/s in a constant direction of North
A person runs at a constant speed of 3 mi/h while turning from the North to the East
A car travels along a curve while slowing down to 60 km/h from 100 km/h
Question 1: For each of the following descriptions of motion, state whether the description indicates a
speed, a velocity, an acceleration, or none of these.
Descriptions
Variable
A domestic cat can run as fast as 13 m/s
We are located at the corner of Los Alisos and Mustang Run
An airplane is moving west at 200 km/h
The 100 mi trip took 2 h
A drag racer, starting from rest, reaches a speed of 100 mi/h in 4 s
A person is at rest.
A cyclist went from traveling at 15 m/s north to 15 m/s east in 20 s
Question 2: What are the two ways that an object can accelerate?
Question 3: The chart below shows several descriptions of motion. For each one, indicate the following:
Whether the object has a constant or changing velocity
Whether the object has is accelerating or not accelerating
Whether the object has a constant or changing speed](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F30cee8b6-5615-43da-aab4-10af486839f1%2F4eaf9c1f-bd8b-468a-96c0-3c6eab36f948%2Ft29gq6a_processed.jpeg&w=3840&q=75)
