In this simulation two mass are connected by a rope running over a
pulley.
1-Dimensional
Kinematics
This page consists of many different gif animations demonstrating the
1-Dimensional Kinematics.
Newton's
Laws
This page consists of several different types of gif animations which
are related to the Newton's Law of Inertia. E.g. free falling.
Kinematics
This page simulates one-dimensional kinematics. Initial velocity, final
velocity, and acceleration can be varied as desire.
Sliding
friction
This page is a laboratory exercise which includes the discussion, the
demonstration and the setup about the experiment. The experiment shows
a box sliding down an inclined plane.
Force
This page is a laboratory exercise which includes the discussion, the
demonstration and the setup about the experiment. The experiment demonstrates
the property that a vector can be resolved into three components.
The demonstration let us to learn about three vectors.
Plot
the graph
This page is a laboratory exercise which includes the discussion, the
demonstration and the setup about the experiment. The exercise talks about
the ideas of plotting different forms of graph.
Linear
motion
This game helps us to determine what factors may affect the stopping
distance of a driving vehicle.
Motion
graph
Motion graphs tell us how far a body has traveled, how fast it is moving
and how the speed changes with time. The common motion graphs are s-t graph,
v-t graph and a-t graph.
Falling
object
This is an animation of different objects falling under gravity on
the earth or on the moon. The displacement-time and velocity-time graphs
are also shown.
Work
This simulation shows a person pulling a box with mass M across a horizontal
surface.
Work

This page consists of many gif animations which gives the basic idea
on what are work and energy, and also the transformation between them.
Projectile
motion
This page provides both the theory and demonstrations of the projectile
motion. In the theory part, it derives several useful equations, e.g. the
range that particle traveled R, the time of flight T, etc.
Projectile
motion
This applet illustrates projectile motion. A body is launched with
fixed speed and with user-variable launch angle and air resistance proportional
to the velocity of the body. The applet animates the resulting trajectory.
Projectile
This Java Applet simulates a projectile being launched from ground
level with an initial velocity (Vo) at an angle.
Vectors
and Projectiles
This page consists of many different gif animations, which gives the
basic description of the projectile motion.
Circular motion, Simple harmonic motion
Simple
Harmonic Motion and Uniform Circular Motion
The uniform circular motion is intimately related to simple harmonic
motion. If we are to look at a side view of a uniform circular motion on
a thumbtack stuck on a rotating table, we will see the thumbtack oscillated
in simple harmonic motion. This java applet let us look at this relation
graphically.
Circular,
Satellite and Rotational Motion
This gif animation provides several different basic descriptions on
the circular and rotational motions, with a discussion on orbiting satellite.
Resonance, forced vibration and damping
The
damped harmonic oscillator
This applet illustrates damped harmonic motion with resistance proportional
to the velocity of the
body. The user enters the damping and the initial conditions, and the
applet animates the body's
motion and plots the position, velocity, and energy as functions of
time.
Conservation of linear momentum
Inelastic
momentum
This simulation simulates a completely inelastic collision. For this
simulation the user can adjust the initial velocity of the red ball, the
mass of the red ball, and the mass of the blue ball.
Elastic
momentum
This simulation demonstrates the transfer of kinetic energy in a completely
elastic collision. For this simulation the user can adjust the initial
velocity of the red ball, the mass of the red ball, and the mass of the
blue ball.
Momentum

This page consists of many gif animations on the concept of momentum
and on car-truck collisions.
Equilibrium of rigid body, rotational motion, angular momentum, torque
Torque
This simulation shows the physics behind a see-saw. The user can enter
the mass and the distance from the mid-point of both objects, then the
relative diagram of the see-saw is shown. It also provides the theory on
torque and the definition of some important terms.
