Greater force is required to set heavier bodies in motion Momentum is the product of mass of a body & its velocityįor example, A ball of 1 kg moving with 10m/sec has a momentum 10kg m/sec. Momentum plays a crucial role in Second law. The second law is for scenarios with net force not equal to 0. Newton’s first law was for scenarios where net force = 0. However, if Team 1 exerts more force than Team 2, then there would be a net movement towards Team 1 and Team 1 would win. Displacement Relation for a Progressive WaveĪ body at rest tends to remain at rest and a body in uniform motion tends to remain in the state of uniform motion until & unless an external force is applied on it.įor example, a ball lying on the table at rest will remain at rest until an external force is applied on it.īalanced & Unbalanced forces :- Balanced Forces:įor example, in Tug of war, If teams 1 & 2 apply equal forces in opposite directions, there would be no net force.Reflection of Transverse and Longitudinal Waves.Some Systems Executing Simple Harmonic Motion.Velocity and Acceleration in Simple Harmonic Motion.Simple Harmonic Motion and Uniform Circular Motion.Kinetic Theory of Gases - Concept of Pressure.Interpretation of Temperature in Kinetic Theory.Introduction of Kinetic Theory of an Ideal Gas.Qualitative Ideas of Black Body Radiation.Ideal-gas Equation and Absolute Temperature.Introduction of Mechanical Properties of Fluids.Excess of Pressure Across a Curved Surface.Atmospheric Pressure and Gauge Pressure.Application of Elastic Behaviour of Materials.Determination of Young’s Modulus of the Material of a Wire.Behaviour of Perfect Gases and Kinetic Theory of Gases.Thermodynamic State Variables and Equation of State.Values of Moments of Inertia for Simple Geometrical Objects (No Derivation).Comparison of Linear and Rotational Motions.Momentum Conservation and Centre of Mass Motion.Angular Momentum in Case of Rotation About a Fixed Axis.Dynamics of Rotational Motion About a Fixed Axis.Kinematics of Rotational Motion About a Fixed Axis.Theorems of Perpendicular and Parallel Axes.Angular Velocity and Its Relation with Linear Velocity.Linear Momentum of a System of Particles.System of Particles and Rotational Motion.Acceleration Due to Gravity and Its Variation with Altitude and Depth.Acceleration Due to Gravity Below and Above the Earth's Surface.Acceleration Due to Gravity of the Earth.Motion of System of Particles and Rigid Body.Motion in a Plane - Average Acceleration and Instantaneous Acceleration.Cases of Uniform Acceleration Projectile Motion.Scalar (Dot) and Vector (Cross) Product of Vectors.Motion in a Plane - Average Velocity and Instantaneous Velocity.Motion in a Plane with Constant Acceleration.Addition and Subtraction of Vectors - Graphical Method.Multiplication of Vectors by a Real Number or Scalar.Non - Conservative Forces - Motion in a Vertical Circle.Various Forms of Energy : the Law of Conservation of Energy.Work Done by a Constant Force and a Variable Force.Notions of Work and Kinetic Energy: the Work-energy Theorem.Relations for Uniformly Accelerated Motion (Graphical Treatment).Position-time, Velocity-time and Acceleration-time Graphs.Elementary Concept of Differentiation and Integration for Describing Motion.Acceleration (Average and Instantaneous).Kinematic Equations for Uniformly Accelerated Motion.Introduction of Motion in One Dimension.Law of Conservation of Linear Momentum and Its Applications.Examples of Circular Motion (Vehicle on a Level Circular Road, Vehicle on a Banked Road).Dynamics of Uniform Circular Motion - Centripetal Force.Circular Motion and Its Characteristics.Dimensional Analysis and Its Applications.Dimensional Formulae and Dimensional Equations.Accuracy, Precision and Least Count of Measuring Instruments.Physics Related to Technology and Society.
