Q
  • Is a form of energy released from the nucleus, the core of atoms, made up of protons and neutrons.
A

NUCLEAR ENERGY

17
Q
  • when nuclei of atoms split into several parts
A

Fission

18
Q

when nuclei fuse together.

A

Fusion

19
Q
  • The type of energy that is used in an x-ray imaging. Least familiar form of energy but most important in radiology. is a special kind of energy that travels in waves through space. It is a like a wave of energy that can move without needing anything else to carry it, even in empty space.
A

ELECTROMAGNETIC ENERGY

20
Q
  • These are the waves that allow us to listen to the radio. They have long wavelengths and low frequences. are used for broadcasting music, news, and other information.
A

RADIO WAVES

21
Q
  • Have shorter wavelengths and higher frequencies than radio waves. They are used in microwave ovens to cook and heat food. They are also used for communication, such as cell phones and wifi.
A

Microwave

22
Q
  • Is sometimes called heat radiation because we feel it as warmth. It has longer wavelengths than visible light. is used in devices like TV remote controls and thermal cameras.
A

INFRARED RADIATION

23
Q
  • This is the type of electromagnetic radiation that allows us to see the world around us. comes in different colors like red, orange, yellow, green, blue, indigo, and violet. Each color has a different wavelength.
A

Visible light

24
Q
  • Has shorter wavelengths and frequences than visible light. It comes from the sun and is responsible for causing sunburns. We can’t see UV radiation but it can be harmful to our skin and eyes.
A

ULTRAVIOLET RADIATION

25
Q
  • have even shorter wavelengths and higher frequences than UV radiation. They can pass through our bodies and are used in medical imaging, like x-ray machines, to see our bones and organs.
A

X-RAY RADIATION

26
Q
  • Have the shortest wavelengths and highest frequencies of all the radiations. They are produced during nuclear reactions and can be very harmful. Scientists use this rays to treat cancer.
A

GAMMA RADIATION
.

27
Q
  • Numerical quantity assigned to every point in space that changes in time.
A

FIELDS
.

28
Q

Is an influence that can cause an object to change its velocity.

A

Force/forces

29
Q
  • Is an invisible pulling force between two objects. The strength this force depends on an object.
A

GRAVITATIONAL FORCE

30
Q
  • The force that allows protons to turn into neutrons and vice versa through beta decay. Acts inside of individual nucleons.
A

WEAK NUCLEAR FORCE

31
Q
  • The force of attraction between unlike charges or repulsion between like charges is attributed to the electric field.
A

ELECTROSTATIC FORCE

32
Q
  • This force is strong enough that overcomes the repulsive force/electrostatic force between two-charge. Allowing two same charge to stick together.
A

STRONG NUCLEAR FORCE

33
Q
  • Generalized rules to explain a body of observations in the form of verbal or mathematical statement.
A

Laws

34
Q
  • Is an invisible pulling force between two objects. The strength of this force depends on an object mass.
A

LAW OF UNIVERSAL GRAVITATIONAL

35
Q

a body will remain at rest or will continue to move with constant velocity in a straight line unless acted on by an external force.

A

INERTIA

36
Q

-is an influence that can cause an object to change its velocity

A

FORCE

37
Q

for every action there is an equal and opposite reaction.

A

Action/reaction

38
Q

States that energy can neither be created nor destroyed. It only converted from one form of energy to another.
The total amount of energy in a system remains constant, even as that energy is transferred or converted.

A

LAW OF CONSERVATION OF ENERGY

39
Q
  • Principle that states that matter can be neither created nor destroyed. It converts one form of matter into another.
    The properties and mass of that matter remain constant even as that matter transform into different states of matter: solid, liquid, gas.
A

LAW OF CONSERVATION OF MASS
