Introduction4:18
Explore one-dimensional kinematics by defining position, displacement, speed, velocity, acceleration, and distance traveled. Use calculus to derive the position-time relation and, from it, determine velocity and acceleration for predicting motion.
Position Vector and Displacement Vector8:46
How to find Average of a Quantity11:39
Velocity and its direction12:40
Example on finding velocity from position5:59
Speed and intricacies in its definition7:46
Explore how speed equals the magnitude of velocity and also the rate of change of distance traveled, and how displacement versus distance traveled relate in infinitesimal limits.
Displacement and Distance Travelled from Velocity and Speed6:25
Average Speed and Average Velocity5:21
Definition and Direction of Acceleration10:08
Acceleration is the rate of change of velocity, caused by a nonzero net force, and points in the direction of that net force.

Special case of Constant Acceleration10:59
Derive the velocity time relation for constant acceleration via a differential equation and integration, yielding velocity equals initial velocity plus acceleration times time, and decompose the vector into independent directions.
The first two equations of motion9:47
Derives the two equations of motion for constant acceleration: v = u + a t and s = u t + 1/2 a t^2, via integration, clarifying displacement vs distance.
The third and fourth equations of motion14:50
Derives the third and fourth equations of motion for constant acceleration, including v^2 = u^2 + 2 a s and s = (u+v)/2 t.
The only scalar equation of motion8:52

One Dimensional Kinematics Definitions10:35
Define one-dimensional rectilinear motion along the x axis, with position x, velocity along x, and acceleration along x. Derive constant-acceleration equations and key relationships between velocity, position, and time.
Different Possible Problems in One Dimensional Kinematics12:03
Examine common one-dimensional kinematics problems, deriving position-time relationships from velocity-time or acceleration-time data, and solving cases via integration across velocity, acceleration, and position relations.

Problem with Velocity vs Time relation given13:14
Explain one-dimensional motion with velocity that changes linearly over time, derive position as x = 4t - t^2, identify constant acceleration, and distinguish displacement from distance traveled.
A beautiful problem on finding distance travelled in rectilinear motion13:10
Problems on Acceleration vs Time and Velocity vs Position9:40
Problem on Acceleration vs Velocity relation9:34
Problem on Acceleration vs Position Relation (Encountered in Oscillations)9:22
Minimum distance between police and thief12:08
A Tricky Problem on Retarding Car10:44
A Helicopter Problem11:00
Calculate the helicopter's velocity at engine-off by using vertical acceleration 3 m/s^2, displacement, and the last sound travel time to the observer.
A Problem of Acceleration Reversal9:04
Explore a one-dimensional motion problem with zero initial velocity and acceleration reversal, and determine the time to return to start using kinematics from a to b and b to c.

Motion Under Gravity13:31
Explore motion under gravity by analyzing a ball thrown upward and returning to ground, using downward as positive, and applying constant-acceleration kinematics to find time of flight and maximum height.
Three problems on motion under gravity12:31
Problem on motion inside an elevator11:59
A Problem of Stone thrown from top of wall upwards10:24
This one-dimensional kinematics lecture analyzes a stone thrown upward at 5 m/s from a 30 m wall, landing in 3 seconds under 10 m/s^2 downward, using a whole-motion method.

Requirements

Requires you to know Vectors , Differential and Integral Calculus

Description

Note: This course is intended for purchase by adults (above 18 years) or by parents or guardians of students of age below 18

Here you will be introduced to basic definitions of kinematics involving integration which are as follows: distance travelled, displacement, position vector, average speed, average velocity, speed, velocity and acceleration. Each definition is presented very carefully with proper illustrations and examples. This is followed by a discussion on the special case which one often encounters in kinematics namely the case of constant acceleration.. The equations of motion for this case of constant acceleration are derived and their intricacies are thoroughly discussed. This is followed by a discussion on one dimensional kinematics and the types of problems one encounters in them. The focus of this course is mainly on one dimensional kinematics though the definitions are given keeping in view the two and three dimensional kinematics so that at a later stage you can smoothly transition to two dimensional and three dimensional kinematics. The different problems discussed here cover almost all important cases like velocity-time, acceleration-time, velocity-position, acceleration-velocity and acceleration-position relations and questions after giving these relations. I have extensively used vectors and Calculus and I suggest to go through my vectors and differential calculus and integral calculus courses before venturing in to this topic. Special emphasis is given on graphs and graph based problems. The concepts of calculus like "derivative gives slope" and "integration gives area" are used extensively in the discussion on graphs and their problems. After this course you will have basically mastered almost the whole of one dimensional kinematics and ready to take up two dimensional and three dimensional motion

Who this course is for:

For any adult whose is interested in calculus based physics
For parents whose children are below 18 years and preparing for competitive exams like IITJEE or NEET
