# Lever Physics Game Online - Play Free Fun Educational Fulcrum Games

Lever Physics is a challenging, math, physics and equilibrium-based game for upper elementary school / middle school students, high school teens and grownups where you must place and balance weights (fun items and characters) on a 'seesaw-style' beam connected to the ground by a pivot (fulcrum). Playing against the clock, you must place any available weights onto the lever (beam), and try to keep it perfectly balanced in the middle. Don't be fooled by the fun and playful imagery in this load balancing brain-teaser! It is a tricky, analytical thinking puzzle and logic problem solving challenge that requires good observation skills and hard thinking combined with mathematical and engineering solutions. This interactive, point-and-click activity allows some trial and error (by quickly placing, removing and re-positioning weights) but you definitely cannot delay your decisions for long as the clock is ticking fast! Ok Balancing Master, can you 'lever' yourself to the top of the class? Have Fun!

## How to play Lever Physics game online

In each progressively difficult level, you must place all available 'weights' provided onto the beam in their correct positions to balance the Torque created on each side of the fulcrum before the clock runs out. In this free online game you must make quick mathematical calculations in your head, and decide on which point on the beam (distance from the fulcrum) you should place each weight. Using your computer mouse, touchpad or tablet, Left Click and drag a weight toward a placement point. The weight snaps into position once you drag near the placement spot. Release the click to confirm. You cannot hang more than one weight from each placement spot. If the clock runs out before you have completed the task, you must replay the level. For example, you may have two four ton weights (an elephant and a whale). In this instance, to create perfect balance, these weight items would need to be placed at equal distance either side of the fulcrum. As you progress, more weights are introduced, and the calculations become more complex. Enjoy the brain work and creative problem solving when you play this free online game. How do your best friends and family members fare at this challenging activity?

## Quick Physics Revision

A lever is a simple mechanical device which consists of a beam or stick or rod, and helps to lift weights with less effort. To be effective (as a lever), it must have a support to pivot on. This pivot is called a fulcrum. Levers can then be used to exert a large force over a small distance at one end of a structure by exerting only a small force over a greater distance at the other end of the same structure (beam).

## The Law of Equilibrium

A lever is in equilibrium when "the load" and "the effort" balance each other. The effort (weight) multiplied by its distance from the fulcrum = the load (weight) multiplied by its distance from the fulcrum. This law of equilibrium is true for all classes of levers. For example, 2 pounds of effort exerted 4 feet from the fulcrum will balance 8 pounds located 1 foot on the other side of fulcrum. This effort times (multiplied by) distance about the fulcrum is the "Torque" (rotational force).
