Newtons Laws
Which of Newton's Laws states that for every action there is an equal and opposite reaction
Newton's third law
What are the two types of waves?
longitudinal and transverse
What is the electromagnetic spectrum?
The electromagnetic spectrum is the range of all types of electromagnetic radiation, arranged by wavelength and frequency
What are the four main states of matter?
Solid, liquid, gas, plasma.
What is energy?
Energy is the capacity to do work. It's what allows things to move, change, or create change in their surroundings.
According to Newton's 2nd Law, if there is an increase in force, what will happen to the acceleration of the object? What is the formula?
It will increase, F=ma
What is a wave?
A wave is a disturbance that propagates (moves) through a medium, transferring energy without transferring matter.
What color has the longest wavelength?
Red
also radio waves
In what state of matter are particles packed most closely together?
Solid and the opposite would be plasma.
What are some examples of different types of energy
Some common types of energy include kinetic energy (energy of motion), potential energy (stored energy), thermal energy (heat), electrical energy, and chemical energy.
Which of Newton's Laws describes inertia?
Newton's 1st Law
What is an interference?
Interference is the phenomenon that occurs when two waves overlap and combine to form a new wave.
What are the main components of the electromagnetic spectrum, ordered from lowest to highest energy?
Radio waves, microwaves, infrared, visible light, ultraviolet, X-rays, and gamma rays.
What is the process called when a liquid turns into a gas?
Evaporation
What is the difference between potential and kinetic energy?
Potential energy is stored energy, like a stretched rubber band or a ball held high in the air. Kinetic energy is the energy of motion, like a moving ball or a car.
What does Newton's second law of motion state about an object's acceleration?
the acceleration of an object depends upon two variables – the net force acting on the object and the mass of the object.
What are some examples of mechanical waves?
Sound waves, water waves, and seismic waves.
Which type of electromagnetic radiation is the most energetic?
Gamma rays have the most energy.
What is the process called when a gas turns into a liquid?
Condensation
What is the law of conservation of energy?
The law of conservation of energy states that energy cannot be created or destroyed, but it can be transformed from one form to another.
The law of conservation of momentum states that when two objects collide, what happens to their combined momentum?
It remains the same
What are some examples of electromagnetic waves?
Light, radio waves, microwaves, infrared radiation, ultraviolet radiation, X-rays, and gamma rays.
What are some practical applications of different parts of the electromagnetic spectrum?
Radio waves are used for communication, microwaves for cooking, infrared for remote controls, visible light for vision, ultraviolet for sterilization, X-rays for medical imaging, and gamma rays for radiation therapy.
What is the process called when a solid turns into a liquid?
Melting
What are some examples of how energy is transformed?
