Explore a 3D pendulum with adjustable length, mass, initial angle, gravity, and damping. Watch the θ(t) graph update live and discover that period depends only on string length and gravity — not mass. Try Moon, Mars, and Jupiter gravity settings!
Visualize 2D projectile trajectories with adjustable launch angle, initial velocity, and gravitational acceleration. Observe how each parameter affects range, maximum height, and time of flight in real time.
Explore mass-spring oscillations and energy transformations. Adjust mass, spring constant, and damping to observe how frequency, amplitude, and energy interchange between kinetic and potential forms.
Visualize uniform circular motion with adjustable radius and speed. See how centripetal acceleration and net force always point toward the center, and explore the role of tension, gravity, and normal force.
Interactively balance forces on a rigid lever by placing masses at different distances from the pivot. Observe torque magnitudes and directions, and understand the condition for rotational equilibrium.
