How air pushes a plane upward

Spin turns air into a sideways push

Warm air makes the balloon less dense

Calculate trajectory, range, max height, and time of flight for projectile motion. Visualize the parabolic path with an interactive time slider and velocity vectors.

Calculate voltage, current, resistance, and power with Ohm's law. Build series and parallel resistor networks with step-by-step equivalent resistance.

Visualize image formation with interactive ray diagrams for lenses and mirrors.

Solve constant-acceleration problems with step-by-step solutions and motion graphs.

Solve Bernoulli's equation and the continuity equation for pipe flow. Explore Torricelli's theorem, Venturi effect, Reynolds number, and airplane wing lift

Change pipe radius, length, pressure difference, and fluid viscosity to see how the volumetric flow rate responds through the Hagen-Poiseuille law. Verify the fourth-power radius dependence (doubling the radius multiplies the flow by 16), watch the parabolic velocity profile, and check whether the flow stays laminar with the Reynolds number

Explore hydrostatic pressure using a U-tube manometer simulation. Vary fluid density (water, oil, mercury, glycerin) and depth to observe pressure changes via P = rho*g*h. Displays gauge pressure, absolute pressure, and pressure in multiple units (Pa, atm, bar, mmHg, psi). A fluid-height visualization shows the manometer response.

Explore Pascal's law, hydraulic presses, and hydrostatic pressure. Calculate force multiplication, mechanical advantage, and pressure at depth with interactive diagrams

Explore heat, temperature, gas behavior, and phase changes - from calorimetry and the ideal gas law to fluid dynamics and phase diagrams.
