newton’s laws of motion 1st when Net force acting on an object is zero, objects will not motion 2nd acceleration of an objects is equal to the net force acting On that object divided by the object mass 3rd when An object applies a force on the second object, the second object applies an Equal and opposite force to the first object in different object indifferent Direction.

Work: when a force is Apply on an object and it moves over a certain distance.

Friction: force that Resist motion of an object is called friction

The law of conservation of energy: it states that energy can neither be created nor Destroyed but can be transform one form to another

Distinguish between kinetic and potential energy: kinetic energy is the energy due to motion of an object While a potential energy is the stored energy that an object on the energy at Rest of an object.

Name 3 types of potential energy: gravitational, chemical and elastic potential energy

An atom: is the smallest Invisible particle of an element which takes part in a chemical reaction.

An isotope: Are atoms of The same element having the same atomic number but different atomic mass.

Periodic table: a chart That shows the arrangement of elements in rows and column

Motion: it is the process Of changing position

What is an acceleration of an object: it is a measure of the change in velocity during a Period of time

The kinetic energy of an object depends on its mass and speed

Nuclear energy is energy that is stored in the nucleus of an atom

Electrical energy is the form of energy carried by an electric current

Work is The transfer of energy that occurs when a force is applied over a distance

Potential Is the stored energy of an object
