Elasticity is a term in physics used to describe the ability of an object to return to its original form after being distorted. Examples of objects with elasticity are piano wires, springs and rubber bands. More »

The laws of motion and mass, as well as conservation and transfer of chemical, elastic and kinetic energy, are some of the physics concepts demonstrated with a toy slingshot. Use of the slingshot also demonstrates how va... More »

Robert Hooke was an influential, experimental scientist in the 17th century. He studied all forms of science including astronomy, chemistry, biology, physics, geology and paleontology. More »

In physics, "displacement" is defined as the change in position of an object, including how far the object travels and in what direction. If an object moves around but returns to its original position, the object will mo... More »

In physics, energy is a system's capacity to perform work, which is force acting on an object. Energy has many forms, including kinetic or mechanical energy, potential energy, light energy and heat energy. The basic rule... More »

In physics, the tension on a suspended object said to be equal to the weight of the object plus or minus the mass of the object times the acceleration acting on it. In other words, this is the weight of the object plus o... More »

In physics and chemistry, the term "E" is often used as an abbreviation for energy in equations. Since energy can take different forms and has various relationships with matter, motion, light and other scientific concept... More »
