Projectile motion 1
Projectile motion is the motion of an object under the influence of gravity. It can be broken down into two components: horizontal motion and vertical motion. Horizontal motion is unaffected by gravity and follows the regular kinematic equations of straight line motion. Vertical motion is affected by the downward acceleration due to gravity and also follows straight line kinematic equations using the acceleration due to gravity. Understanding projectile motion requires analyzing the horizontal and vertical components separately using the appropriate kinematic equations for each direction.

2.1 linear motion
Kinematics is the study of linear motion. Key terms include displacement, velocity, and acceleration. Displacement is the distance from a starting point, velocity is speed in a direction, and acceleration is the rate of change of velocity. Average values are calculated by total distance or displacement over total time. Instantaneous values give a clearer picture of motion at a moment in time and can be derived from graphs of displacement, velocity, and acceleration over time. When acceleration is constant, five equations can be used to describe motion with constant acceleration.

12 rotational motion
The document discusses rotational motion and angular quantities. It defines angular displacement, velocity, and acceleration and describes how they relate to linear motion. It discusses torque as the product of force and lever arm that produces rotational acceleration. The moment of inertia depends on an object's mass distribution and axis of rotation, and determines the rotational acceleration produced by a torque. Rotational kinetic energy is defined analogously to linear kinetic energy, using angular quantities rather than linear ones.
Projectile motion
This document discusses projectile motion, beginning with an overview of the objectives and definitions. It explains that a projectile experiences only gravity and air resistance, and its motion can be analyzed as independent vertical and horizontal components. Horizontal projectiles follow the simplest case where velocity is constant horizontally but follows parabolic free fall vertically. Non-horizontal projectiles require calculating initial velocity components and analyzing changes in vertical velocity over time. Solving projectile motion problems generally involves drawing diagrams, choosing a coordinate system, and applying the independent kinematic equations along each axis. Air resistance decreases a projectile's range from the ideal parabolic trajectory.

2) It provides examples of how to determine the velocity and acceleration of planes in formation and a roller coaster car moving along a fixed helical path using their x, y, and z coordinates.
3) The document also gives an example problem solving for the collision point and speeds of two particles moving along curved paths given their position vectors as functions of time.
Gravitational Fields
1) Newton proposed that all objects with mass attract each other with a force directly proportional to the product of their masses and inversely proportional to the square of the distance between them.
2) An object in free fall experiences a sensation of weightlessness because both it and the elevator/spacecraft it is in are accelerating downward at the same rate due to gravity, so there is no relative acceleration between them.
3) A satellite in orbit around a planet is weightless because the centripetal acceleration needed to maintain its orbit exactly counteracts the acceleration due to gravity, resulting in no net acceleration felt by objects in the spacecraft.

Free body diagrams show the relative magnitude and direction of all forces acting upon an object by isolating it from its surroundings. The document provides examples of free body diagrams for the Statue of Liberty, a sitting gorilla, a wooden swing, a bungee jumper's bucket, a traffic light, and the pin at point A of a truss bridge.

Examples are given to illustrate momentum, inertia, and conservation of momentum. Multiple choice and short answer questions from an NCERT textbook are also included.
Moments
(1) The document discusses moments, which are turning forces that cause an object to rotate rather than push it linearly. Moments depend on the magnitude of the applied force and its distance from the pivot point.
(2) To calculate the moment of a single force, the formula is Moment = Force x Perpendicular Distance from the pivot. When multiple forces are present, their individual moments are summed.
(3) Systems in equilibrium have their clockwise and counter-clockwise moments equal, allowing one to solve for unknown values like reactions at supports. Diagrams are drawn and moments taken to set up and solve equations of equilibrium.

Inequalities quadratic, fractional & irrational form
To solve quadratic, fractional, irrational, and absolute value inequalities, one should:
1. Make the right-hand side zero by shifting terms to the left-hand side
2. Fully factorize the left-hand side to find critical values
3. Draw a sign diagram for the left-hand side using the critical values
4. Determine the range of values for the variable based on the sign diagram.
Quadratic Equations
This presentation includes the roots of quadratic equation, the nature of the roots, minimum and maximum values and quadratic inequality
Application of differentiation
This presentation explains how the differentiation is applied to identify increasing and decreasing functions,identifying the nature of stationary points and also finding maximum or minimum values.
Inequalities
This document outlines procedures for solving quadratic, fractional, and irrational inequalities. It describes making the right-hand side zero, fully factorizing the left-hand side to find critical values, drawing a sign diagram, and determining the range of values from the sign diagram. Examples are provided for finding the range of values for given inequalities of each type.
Vectors in 2 Dimensions
Vectors in 2D describes scalar and vector quantities. Scalar quantities only have magnitude, while vector quantities have both magnitude and direction. The document explains that two ships sailing the same distance but with different bearings will not end up at the same place, and an airplane traveling the same speed but in different directions will also not reach the same destination. It also demonstrates how to find the magnitude of a vector using the Pythagorean theorem and defines two vectors as equal if they have the same magnitude and direction.
Further trigonometry identities
This presentation shows how sum and difference of angles formula are derived. It also features doubled-angled formula and other trigonometry formulas.
2 circular measure arc length
The document discusses calculating arc length and the area of a sector of a circle. It defines that the arc length s is equal to the radius r multiplied by the central angle θ in radians. The area of a sector is equal to (1/2) * r^2 * θ, where θ is in radians. It provides examples of calculating arc length when given r and θ, and the area of sectors when given r and the central angle measure.
1 resource radian measure and arc length
This document discusses radian measure and its use in measuring angles and arcs in circles. It defines a radian as the angle subtended at the center of a circle by an arc equal in length to the radius. The document provides formulas for converting between radian and degree measures. Specifically, it states that 1 radian is equal to 180/π degrees, or approximately 57.3 degrees. Examples are given to demonstrate calculating radian measures given arc lengths and radii, and to convert between radians and degrees.
Equation of a Circle
1) The document discusses the equation of a circle and how to derive it using the Pythagorean theorem and distance formula.
2) For a circle with center (0,0), the equation is x^2 + y^2 = r^2, where r is the radius.
3) More generally, for a circle with center (a,b), the equation is (x-a)^2 + (y-b)^2 = r^2, where (a,b) are the coordinates of the center and r is the radius.
