Atoms are collections of tiny bits of electricity, which we call protons, neutrons, and electrons. They are so small you can't see them, except with an electron microscope.

Protons

A proton is a tiny particle, smaller than an atom. Protons are too small to see, even with an electron microscope, but we know they must be there because that's the only way we can explain how atoms behave. To give you an idea how small a proton is, if an atom was the size of a football stadium, then a proton would still be smaller than a marble.

Neutrons

A neutron is a tiny particle like a proton, smaller than an atom. Like protons, neutrons are too small to see, even with an electron microscope, but we know they must be there because that's the only way we can explain how atoms behave. All neutrons, everywhere in the universe, are exactly the same, and pretty much all of them are inside atoms.

Electron

An electron is a tiny piece of electricity, with hardly any mass. It is too small to see even with an electron microscope.

In combination reactions, two or more reactants form one product. The reaction of sodium and chlorine to form sodium chloride,

2Na(s) + Cl2(g) -> 2 NaCl(s)

and the burning of coal (carbon) to give carbon dioxide,

C(s) + O2(g) -> CO2(g)

Time and Distance

By one dimension we mean that the body is moving only in one plane and in a straight line. Like if we roll a marble on a flat table, and if we roll it in a straight line (not easy!), then it would be undergoing one-dimensional motion. There are four variables which put together in an equation can describe this motion. These are Initial Velocity (u); Final Velocity (v), Acceleration (a), Distance Traveled (s) and Time elapsed (t). The equations which tell us the relationship between these variables are as given below.

v = u + at

v 2 = u 2 + 2as

s = ut + 1/2 at 2

Newton's laws of motion

Through Newton's second law, which states: The acceleration of a body is directly proportional to the net unbalanced force and inversely proportional to the body's mass, a relationship is established between

Force (F), Mass (m) and acceleration (a). This is of course a wonderful relation and of immense usefulness.

F = m * a

Power

Power (P) is work( W) done in unit time (t).

P = W/t

Momentum

Momentum (p) is the quantity of motion in a body. A heavy body moving at a fast velocity is difficult to stop. A light body at a slow speed, on the other hand can be stopped easily. So momentum has to do with both mass and velocity.

p = mv

Newton's law of universal gravitation

If F is the force due to gravity, g the acceleration due to gravity, G the Universal Gravitational Constant (6.67x10-11 N.m2/kg2), m the mass and r the distance between two objects.

Then

F = G m 1 m 2 / r 2
