Work Done on a Block (Work-Energy Principle)
This simulation demonstrates the effect of forces acting on a block across a distance through three perspectives: kinematics, dynamics and energy changes.
In the simulation, the block is made to travel through three regions, A, B and C.
In region A: The block experiences an applied force to the right across a frictionless surface.
In region B: The block experiences no horizontal force as it slides to the right across a frictionless surface.
In region C: The block experiences friction only as it slides across a rough surface1.
1Note: friction is zero when the block is motionless and is not attempting to move from rest
Step 1: Adjust values
driving force: key desired value in input field
initial displacement: drag2 the box between - 1.0 m <x < - 0.4 m
mass (of block): key desired value in input field3
friction (in region C): key desired value in input field3
2Note: you are also allowed to drag the box for the range x > - 0.4 units, however, the conditions of regions B and C still apply
3Note: values of mass and friction are co-dependent, i.e. changing one value will affect the other
Step 2: Play/Step-play/Pause Simulation
Play: runs the simulation
Step-play: runs the simulation in steps with each click
Pause: pauses the simulation
Step 3: Data Analysis
Resultant force, friction, mass, kinetic energy, thermal energy, total energy, time
Motion graphs: displacement-time, velocity-time, acceleration-time
Energy graphs: kinetic energy-time, thermal energy-time, total energy, energy-time (layering of all three aforementioned graphs)
