Matter
What is the definition of matter?
What is anything that has mass and takes up space?
What is the formula used to calculate an object's speed?
What is speed = distance/time?
What is a push or a pull?
What is the relationship between kinetic and potential energy?
What is as potential energy decreases in a system, kinetic energy increases and vice versa?
What is they combine to make total mechanical energy?
Mechanical waves require a _________ to transfer energy.
What is a medium?
What are the three states of matter IN ORDER of energy from least to most?
What are Solid, Liquid, Gas?
This term describes both speed and direction.
What is velocity?
What term describes forces that cancel each other out, resulting in no change in motion?
What are balanced forces?
Describe the energy transformation in a generator?
What is mechanical energy transforming into electrical energy?
Describe the relationship between frequency, wavelength, and amplitude in a wave.
What is as wavelength increases, frequency decreases? Amplitude determines the height of the wave and affects the amount of energy it transfers.
Explain the difference between a physical and chemical change.
A physical change alters the form or appearance of a substance without changing its composition.
A chemical change results in the formation of a new substance with different properties.
The rate of change of velocity is known as what?
What is acceleration?
What happens when a negatively charged object comes close to a positively charged object?
What is "opposites attract"?
According to the law of conservation of energy . . .
When a wave passes from one medium to another, it is called _____________.
What is refraction?
Describe the properties of matter in each of its forms.
Solids: definite shape, definite volume
Liquids: indefinite shape, definite volume
Gases: indefinite shape, indefinite volume
Identify the property of motion described in Newton's first law.
What is inertia?
How do you increase the strength of an electromagnet?
What is increase the number of coil turns?
Which term describes energy being transferred from one object to another without direct contact (e.g. the sun transferring energy to a flower)?
What is radiation?
Provide the types of electromagnetic waves in order from least energy to most.
What are radio, microwave, infrared, visible light, ultraviolet, x-ray, gamma?
What is the simplest form of matter that retains its unique properties?
What is an element?
What is Newton's second law?
What is F=ma (Acceleration and force are directly related)?
Define gravity.
What is a universal force of attraction between all objects with a mass?
Describe the energy transformation that allows humans to exercise.
What is light energy from the sun --> chemical energy in a plant --> chemical energy in food --> kinetic energy allowing the body to move --> thermal energy producing sweat?
Describe the difference in particular motion between transverse and longitudinal waves.
What is particles move perpendicular to the motion of the wave in a transverse wave and parallel in a longitudinal wave?
