SCIENVE T1 EXAM Flashcards
What are the states of matter
Solid, liquid, gas
What are the forms of matter
Mechanical, electrical, chemical, radiant (light), thermal (heat), sound, nuclear
Law of conversation of energy
Energy can neither be created nor destroyed
What type of energy are examples of transverse waves
Electromagnectic waves
What types of energy is an example of longitudinal waves
Mechanical energy
y
What three scales do we use to measure temperature
Fahrenheit, Celsius, kelvin
What is the relationship between speed, wavelength and frequency of a wave
Speed = wavelength x frequency
Sketch a concave lens
Sketch a convex lens
Recall the 3 subatomic particles of an atom
Protons, neutrons and electrons
Describe what creates static energy
Static energy, or static electricity, is created by the transfer of electrons between different materials when they come into contact and then separate.
What is current what is it measured in and how is it measured
Electric current is the flow of electric charge, measured in amperes (A) or “amps,” and is measured using an ammeter, which is connected in series with the circuit.
What is voltage what is it measured in and how is it measured
is the electrical “pressure” that drives electric current through a circuit, and it’s measured in volts (V) using a device like a multimeter
what is resistance what is it measured in and how
Resistance is the opposition to the flow of electric current, measured in ohms (Ω), and can be determined using a multimeter or by applying Ohm’s Law (Resistance = Voltage / Current)
What are three necessary components of a circuit
A basic electric circuit requires a power source, a conductive path (like wires), and a load (the device that uses the electricity)
