branch of zoology that deals with fishes.

branch of zoology that deals with insects.

deal with the study of nonliving things. - Under ___ are chemistry and physics.

is the study of matter, its composition, the changes it undergoes, and the energy involved in its changes.

the study of force, matter, and energy. It deals with mechanics, heat, electromagnetism, wave motion, optics, and nuclear physics.

refers to motion of objects and to the forces acting upon objects that tend to cause or prevent motion.

concerned with the study of temperature and its effect on the properties of matter.

the study of electricity and magnetism which include electric and magnetic fields and their interactions, the motion of electric charges through conductors, and simple electric circuits

involves the transfer of energy by means of a periodic disturbance through a medium.

the study of the nature and behavior of light and its passage through different media.

deals with the study of x-rays, radioactivity, energy of nuclear particles, fission, and fusion.

inferred the presence of nucleus as a dense mass with positive charge and that the atom is made up mostly of space.

discovered the presence of radioactivity as invisible energy from a radioactive uranium ore. Radioactivity affects or exposes photographic films.

discovered uranium used for cancer therapy.

assisted Madame Curie in studying polonium.

formulated the Theory of Relativity

described static electricity from lightning to ground.

described the force between two charged bodies as proportional to the product of the charges and inversely proportional to the square of the distance between them, that its, Force = (k q1 q2 )/D 2 where force is in Newton, charge q is in coulomb; distance D is in meters; and electrostatic constant k is equal to 9.00 x 109 N-m 2 /coulomb 2

invented the first practical source of steady current.

showed the relationship between voltage, resistance and curren

states that the potential difference across a resistor is equal to the product of the current in it and its resistance.

showed how a current carrying wire produced a magnetic field. It became the basis for producing electromagnets.

discovered the conversion of mechanical energy to electrical energy.

determined the direction of the induced current.

discovered the Laws of Motion.

An object is set to motion if an outside force is applied and will continue moving unless an outside force is applied to it. Friction due to the ground’s surface and the particles in the air may account for force that will eventually allow a moving object to stop.

Acceleration is directly proportional to the net force acting on the body and inversely proportional to its mass.

For every action there is an equal and opposite reaction. This paved way to the invention of jet propulsion, and rocket launching.

invented the telephone.

explained the frequency of waves between transmitter and receiver. Kilohertz defines

explained electromagnetic waves.

invented the incandescent bulb

an organized body of ideas as to the truth of something usually derived from the study of several facts relating to it but sometimes entirely a result of exercising the speculative imagination

states that objects attract other objects based on their masses and distances from each other.

states that matter is made of atoms, and that those atoms are themselves made up of smaller particles.

means “making use of, or based on, experience, trial and error, or experiment.”
