    • 1. Motion with constant acceleration

      This program shows motion (along straight line) with constant acceleration as a function of initial velocity and acceleration. You can trace instantaneous velocity, position and displacement of a moving object.

      RUN

      2. Projectile motion

      This programs shows projectile motion as a function of initial velocity and launch angle. You can change these parameters using proper controls. Instantaneous velocity and acceleration (and their components) are displayed.

      3. Work done by variable force

      The program illustrates calculation of the work done by a variable force. In program the area under the curve is divided into a number of narrow strips. It permits to take the force as being reasonably constant over that interval. Using proper control you can make better approximation by reducing the strip width (increasing number of strips) In the limit, the number of strips becomes very large and the area of stripes is very close to the are under F(x) curve (integral).

      4. One dimensional collisions

      This program illustrates one dimensional collision between two balls. You can adjust initial velocity of colliding balls, their mass m and coefficient of restitution.

      RUN

      5. Two dimensional collisions

      This program shows two hard balls colliding, one moving, one at rest. You can adjust initial velocity of the striking ball, ratio of masses and impact parameter.

      RUN
