POTENTIAL ENERGY POTENTIAL ENERGY: Potential energy is the energy possessed by a body due to its position or change in shape is known as potential energy. Its depends on mass, height and acceleration due to gravity of the object. Potential Energy=mgh By SHAMA KHAN INSTITUTE OF MATHEMATICS & SCIENCE

KINETIC ENERGY KINETIC ENERGY: Kinetic energy is the energy possessed by a body because of its motion. It is a scalar quantity and it's depends on mass and velocity of the body. Kinetic energy of a body always positive. Kinetic Energy=(M×V×V)/2

FREE FALL FREE FALL: When a body is moving under the influence of Earth's gravitational pull only with constant acceleration then it is said to be in free fall. By SHAMA KHAN INSTITUTE OF MATHEMATICS & SCIENCE

UNIVERSAL LAW OF GRAVITATION UNIVERSAL LAW OF GRAVITATION: This is defined as, every particle of matter in the universe attracts every other particle with a force which is directly proportional to the product of their masses and inversely proportional to the square of the distance between them. By SHAMA KHAN INSTITUTE OF MATHEMATICS & SCIENCE

GRAVITATIONAL CONSTANT (G)/ DEFINATION GRAVITATIONAL CONSTANT: Universal gravitational constant is the force of attraction between two point masses of one kilogram each kept at a distance of one metre. G=F By SHAMA KHAN INSTITUTE OF MATHEMATICS & SCIENCE

ACCELERATION DUE TO GRAVITY (g) ACCELERATION DUE TO GRAVITY: It is defined as the acceleration of a body due to attraction of the earth towards its centre is known as acceleration due to gravity. NOTE: It is represented by g and the value is 9.8 metre per second square.

NEWTON'S THIRD LAW OF MOTION NEWTON'S THIRD LAW OF MOTION: "To each and every action there is always an equal and opposite reaction." NOTE: Action and reaction forces occur simultaneously. It is wrong to think that first action occurs and it is followed by reaction. By SHAMA KHAN INSTITUTE OF MATHEMATICS & SCIENCE

NEWTON'S SECOND LAW OF MOTION: The rate of change of momentum of a body with respect to time is directly proportional to the net external force acting on the body and take place in the direction of force. FORCE=MASS×ACCELERATION By SHAMA KHAN INSTITUTE OF MATHEMATICS & SCIENCE

NEWTON'S FIRST LAW OF MOTION NEWTON'S FIRST LAW OF MOTION: A body at rest will remain at rest and a body in motion will remain in uniform motion unless an unbalanced force act on it to change its state of rest or of uniform motion. By SHAMA KHAN INSTITUTE OF MATHEMATICS & SCIENCE

UNIVERSAL LAW OF GRAVITATION UNIVERSAL LAW OF GRAVITATION: This is defined as, every particle of matter in the universe attracts every other particle with a force which is directly proportional to the product of their masses and inversely proportional to the square of the distance between them. By SHAMA KHAN INSTITUTE OF MATHEMATICS & SCIENCE

CONSERVATION OF LINEAR MOMENTUM CONSERVATION OF LINEAR MOMENTUM: It is stated as when external force acting on a system is zero the total linear momentum of the system remains constant. NOTE: This is also known as Law of Conservation of Momentum. By SHAMA KHAN INSTITUTE OF MATHEMATICS & SCIENCE

RESULTANT FORCE RESULTANT FORCE: The resultant force of a number forces acting on a body is a single force which produces the same effect as produced by all the forces taken together. NOTE: Resultant force is also known as NET FORCE. By SHAMA KHAN INSTITUTE OF MATHEMATICS & SCIENCE

BALANCED AND UNBALANCED FORCES BALANCED FORCES: When balanced force act on a body the acceleration of the body is zero or if a number of forces acting on a body produced zero acceleration then the forces are balanced. UNBALANCED FORCES: If a number of forces acting on a body produced an acceleration in the body then the forces acting are called unbalanced forces. BY SHAMA KHAN INSTITUTE OF MATH...

TYPES OF INERTIA INERTIA OF REST: The resistance offered by a body to change its state of rest is known as inertia of rest. INERTIA OF MOTION: The resistance offered by a body to change its state of uniform motion is known as inertia of motion. INERTIA OF DIRECTION: The resistance offered by a body to change its direction of motion is known as inertia of direction. By SHAMA KHAN INSTITUTE OF MA...
