Science Simulations
Movement on the pulley Two objects are connected by a string on a fixed, frictionless pulley and are moving together. In this case, the mass of the string and pulley is ignored. Since tension \(T\) and … more
Why do light and heavy objects fall at the same time? The change in speed due to gravity is the same for all objects because the force and inertia acting on an object are proportional to … more
The distance covered by an object moving at a constant speed increases proportionally with time. If the distance is plotted against time on a graph, it will result in a straight line with a slope that … more
How to use the simulation Drag the ball with your mouse to free fall it in the air. Drag your mouse on the cliff to observe the parabolic motion. You can change the horizontal speed by … more
Mechanical energy Mechanical energy is the sum of potential and kinetic energy. Mechanical energy = potential energy + kinetic energy Em = EP + EK Mechanical energy conservation Without friction, the sum of an object’s initial … more
