My Physics lectures for High School and College students.

Explore Newton's laws through real-time examples, including free-body diagrams, tensions in connected blocks, friction, and motion on an incline, linking inertia, action–reaction, and mass.

Explore how Newton's laws apply to elevator and friction problems. Learn how normal force and weight change with acceleration, analyze friction on a table, a pulley system, inclined planes.

Explore how Newton's laws govern motion through net forces and f = ma, using free body diagrams. Analyze friction, tension, and centripetal acceleration with vector components and Hooke's law.

Explore the work-energy relationship by defining work as force times displacement, derive kinetic, potential, and elastic energies, and apply energy conservation to roller coaster and spring problems.

Explore energy transformation concepts, including gravitational potential energy, kinetic energy, and elastic energy in springs, and apply conservation of mechanical energy to solve height and velocity problems.

Explore work and energy, study linear momentum and its relation to energy, and apply derivatives, force, and the quadratic equation through practice problems.

Define power as the rate of energy change, derived as force times velocity; relate work to displacement, use dot products for components, and discuss kinetic energy and integrals.

Explore the center of mass and center of gravity, then analyze linear momentum, and differentiate elastic from inelastic collisions using impulse concepts.

Study the rotation of rigid bodies, linking angular velocity and angular acceleration with v = omega r and theta, and master conversions between radians and degrees for practical applications.

Explore torque, angular momentum L = I omega, and rotational inertia I = m r^2, and how these govern energy and power in rotational motion.

Solve torque exercises covering grindstone problems and rotating systems, including angular velocity, angular acceleration, work, inertia, and rolling without slipping on inclines.

Explore torque and rotational motion through step-by-step problems: convert rpm to rad/s, find angular acceleration, compute torque from I and alpha, and apply rotational energy formulas.

Learn how equilibrium requires zero net force and zero net torque, and how center of gravity coincides with center of mass in uniform bodies, illustrated by a meter-bar balance.

Define and compare transverse and longitudinal mechanical waves, explain amplitude and lambda (wavelength), relate velocity to lambda and frequency, and illustrate with sound waves and waves on strings.

Study three-dimensional and overlapping waves, including beating and standing waves, and learn about constructive and destructive interference, nodes and antinodes, and how tension and frequency set wave velocity.
