Time period, frequency, and amplitudeSimple Harmonic Motion (SHM) is a type of oscillatory motion where the restoring force is proportional to displacement and acts in the opposite direction.The time period (T) of SHM is the time taken…
Oscillations, pendulums, and springsOscillation is the repetitive motion of a system about its equilibrium position.Simple Harmonic Motion (SHM) is a special type of oscillation where the restoring force is proportional to displacement…
Definitions and characteristics of Simple Harmonic Motion (SHM)Simple Harmonic Motion (SHM) is a type of periodic motion where the restoring force is directly proportional to the displacement and acts in the opposite direction.The equation governing SHM is F = -…
Satellites: artificial satellites and applicationsAn artificial satellite is a man-made object placed into orbit around a celestial body, primarily Earth.Artificial satellites are launched using rockets or space vehicles.They remain in orbit due to…
Gravitational potential energy, escape velocity, orbital velocityGravitational Potential Energy (U) is the energy possessed by an object due to its position in a gravitational field.The formula for gravitational potential energy is U = -G(m₁m₂ / r), where G is the…
Acceleration due to gravity, variation with altitude and depthThe acceleration due to gravity (g) is the acceleration experienced by an object due to the gravitational pull of the Earth.The standard value of g at the Earth's surface is approximately 9.8 m/s².g…
Newton’s law of gravitationNewton’s Law of Gravitation states that every particle in the universe attracts every other particle with a force directly proportional to the product of their masses and inversely proportional to…
Conservation of energy, powerThe Law of Conservation of Energy states that energy can neither be created nor destroyed, only transformed from one form to another.In an isolated system with no external forces, the total energy…
Work-energy theorem, types of energy (kinetic, potential, etc.)The Work-Energy Theorem states that the work done by all forces acting on an object is equal to the change in its kinetic energy.The mathematical expression for the Work-Energy Theorem is W = ΔKE,…
Definitions and unitsWork is done when a force is applied to an object, and the object moves in the direction of the applied force.The mathematical formula for work is W = F × d × cos(θ), where F is the force, d is the…
