"http://yt.cl.nr/xAQIvJ_QoIs" From within the depths of matter a tiny speck with an extraordinary structure and glorious equilibrium emerges: the atom. This tiny speck is the building block of everything in the universe, from giant stars to the proteins inside the cell. Everything in the universe, without exception, is made up of atoms. 

The following animations represent molecular-level models of three classifications of pure substance based on the chemical bonding involved - metallic (e.g. solid copper), ionic (e.g. solid sodium chloride), and intermolecular (e.g. liquid water, liquid oxygen). Animations comparing substances in different states, and undergoing changes of state, are also listed so that the differences in intraparticle and and interparticle bonding can be discussed. This topic is known for the student misconceptions and confusion it can cause without careful visualisation. Temperature is correlated with the degree of particle movement.

"http://yt.cl.nr/_mCC-68LyZM" If you drop a heavy object and a light object simultaneously, which one will reach the ground first? A lot of people will say the heavy object, but what about those who know both will land at the same time? What do they think? Some believe both objects have the same gravitational pull on them and/or both fall to the ground with the same constant speed. Neither of these things is true, however. The force is greater on the heavy object and both objects accelerate at the same rate as they approach the earth, i.e. they both speed up but at the same rate.

This video aims to tease out the difference between mass and weight by asking people what makes a car difficult to push. The standard answer is that it is difficult to push because it's heavy. But heaviness is a measure of weight, the gravitational pull of the Earth attracting the car to Earth's center. When the car is pushed on a flat road, the force of gravity does not oppose the motion. Instead the resistance felt is an indication of the car's mass which determines its inertia. Inertia is the property of matter that means it tends to resist acceleration - the greater the mass, the less the acceleration for a given amount of force.

Ideally if there is no friction, whether rolling or sliding, even the slightest of the force would make the car move. You could actually be able to move the car with a push of your little finger if there is no friction at
