What are Newton's Laws?
Newton's laws of motion explain the relationship between a physical object and the forces acting upon it.
100
What is a wave?
A wave is a disturbance that transfers energy through matter or space, without causing permanent displacement of the medium.
100
What is the primary source of infrared radiation?
Heat
100
What are the States of Matter?
They are solid, liquid, gas, and plasma.
100
What is energy?
Energy is the ability to do work.
200
What is the formula for Newton's 2nd Law?
F=ma
200
What is wave reflection?
Wave reflection is the bouncing back of a wave when it encounters a barrier or a change in medium.
200
What are three uses of radio waves?
Communication, radar, and satellite transmissions.
200
What is Phase Change?
A physical process where a substance transitions from one state of matter to another.
200
What is the formula of power?
300
Which Newton's Laws states that for every action there is an equal and opposite reaction?
Newton's third law
300
What are the two main types of waves?
Transverse and longitudinal waves.
300
Which type of electromagnetic radiation has the highest frequency?
Gamma rays.
300
What is the process called when a solid changes directly into a gas?
Sublimation
300
What are the two main types of energy?
The two main types of energy are potential and kinetic energy.
400
According to Newton's first law of motion, what will a moving object that is not acted on by an unbalanced force do?
It will continue moving at a constant velocity
400
What is wave interference?
Wave interference occurs when two or more waves overlap in the same space, resulting in either constructive or destructive interference.
400
What are potential dangers of exposure to high levels of ultraviolet radiation?
Sunburn, skin cancer, and eye damage
400
How does pressure affect the boiling point of a liquid?
The greater the pressure, the more energy required for liquids to boil, and the higher the boiling point.
400
What are the three methods of heat transfer?
Conduction, radiation, and convection.
500
What does Newton's second law of motion state about an object's acceleration?
An object is directly proportional to the net force applied and inversely proportional to its mass.
500
How do electromagnetic waves differ from mechanical waves?
Electromagnetic waves do not require a medium to travel and can propagate through a vacuum, while mechanical waves require a medium.
500
How does the energy of electromagnetic radiation change as its frequency increases?
The energy increases.
500
What is plasma, and under what conditions does it typically form?
Plasma is an ionized gas that carries an electrical charge. It forms under extremely high temperatures.
500
What is the law of conservation of energy?
The law of conservation of energy states that energy can neither be created nor destroyed - only converted from one form of energy to another.
