Organic Chemistry making plastic experiment

Carbon is the most remarkable of all elements. Its unique atomic structure enables it to link atoms together in long chains or rings in countless ways - so many that there is a whole field of chemistry, called "organic" chemistry, devoted to studying compounds of carbon. Every living organism, from...

Melting point experiment

Rock is solid, water is liquid, and air is gas - but they do not have to be. Every substance in the world is a solid, liquid, or a gas, yet, given the right conditions, each can change into any of these "states of matter": solid, liquid, or gas. Even rock melts to liquid lava in the heat of a volcano;...

Measuring density lab experiment

When scientists talk about how much something weighs, they usually talk about its mass rather than its weight. Scientifically, you should use the word weight only when talking about the force gravity exerts on a particular object. So density is not the weight bust the mass of 1 cubic centimeter...

Uniform Motion along a Straight Line

This represents an important situation. In this case, the acceleration vector is constant and lies along the line of the displacement vector, so that the directions of v and a can be specified with plus and minus signs. If we represent the displacement by s (positive) if in the positive direction,...

Uniformly Accelerated Motion

Speed is a scalar quantity. If an object takes a time interval t to travel a distance d, then average speed is equal to the total distance traveled divided by time taken: Or Here the distance is the total (along the path) length traveled. Velocity is a vector quantity. If an object undergoes...

Scalars and Vectors

Please note that whenever I mentioned i j and k in a sentence I am referring to the special unit vectors: . A scalar is a quantity that possesses only magnitude. Some example of scalar quantities includes mass, length, time, distance, speed, and density. A vector is a quantity that...
