Free Pendulum Lab Simulator
Pendulum Lab Simulator lets students adjust pendulum length, bob mass, initial angle, and gravity environment while the pendulum animation, angular displacement graph, theoretical period, experimental period, frequency, and maximum speed update in real time.
Built for simple pendulum homework, gravity comparison, period experiments, and lab report practice.
Start Pendulum Lab Simulator here: set length, mass, initial angle, and gravity, then compare T = 2π√(L/g) with the animated experimental period and live angle graph.
Change pendulum length, bob mass, starting angle, and gravity environment to test which inputs affect period.

Theory versus experiment
Pendulum Lab Simulator uses an ideal simple pendulum model. The theoretical period uses the small-angle formula, while the experimental period adds a small amplitude correction for larger angles.
Pendulum Lab Simulator connects controls, animation, formulas, and graphing so learners can see why length and gravity change period while mass does not.
Adjust pendulum length, bob mass, initial angle, and gravity environment, then watch the swing and output cards update immediately.
Compare Earth, Moon, Mars, and custom gravity results while Pendulum Lab Simulator plots angular displacement and explains which factors affect period.
Use this Pendulum Lab Simulator guide to connect simple pendulum variables, period formula, gravity, and lab conclusions.
Choose pendulum length, bob mass, starting angle, and a gravity environment. Start with Earth, 1 m, and 20° for a familiar classroom setup.
Change one input at a time. Increase length to make the swing slower, change gravity to compare planets, and change mass to confirm it does not control period.
Use the theoretical and experimental period cards, frequency, maximum speed, and angular displacement graph to write a clear lab conclusion.
For lab reports, state that ideal pendulum period depends mainly on length and gravity, not bob mass.

Fast answers about Pendulum Lab Simulator length, mass, gravity, angle, period, frequency, and the T = 2π√(L/g) formula.
Yes. Pendulum Lab Simulator runs in the browser and can be used without an account or installation.
Pendulum Lab Simulator uses the small-angle simple pendulum formula T = 2π√(L/g) for theoretical period, where L is pendulum length and g is gravitational acceleration.
In the ideal Pendulum Lab Simulator model, changing bob mass does not change the period. Length and gravity control the period, while mass changes only the visual bob size.
Pendulum Lab Simulator adds a small amplitude correction for larger initial angles, then compares that animated experimental period with the small-angle theoretical period.
Yes. Pendulum Lab Simulator includes Earth, Moon, Mars, and custom gravity so students can see that lower gravity produces a longer period for the same length.
Open Pendulum Lab Simulator, set the pendulum length, mass, angle, and gravity, then watch the swing and angle graph update instantly.
Compare theoretical and experimental period, test the mass effect, and explain which variables control simple pendulum period.
