All 20 flashcards from this kit, free and with no sign-up.
1. What is motion?
Show the answer
Motion is the change in position of an object with respect to time and its surroundings.
2. Define speed.
Show the answer
Speed is the distance traveled by an object per unit time. It is a scalar quantity.
3. What is velocity?
Show the answer
Velocity is the displacement of an object per unit time in a given direction. It is a vector quantity.
4. State the formula for average speed.
Show the answer
Average speed = total distance traveled / total time taken.
5. What is acceleration?
Show the answer
Acceleration is the rate of change of velocity with respect to time.
6. What is uniform motion?
Show the answer
Uniform motion is motion in which an object covers equal distances in equal intervals of time.
7. What is non-uniform motion?
Show the answer
Non-uniform motion is motion in which an object covers unequal distances in equal intervals of time.
8. What is the SI unit of speed?
Show the answer
The SI unit of speed is meter per second (m/s).
9. What is the SI unit of acceleration?
Show the answer
The SI unit of acceleration is meter per second squared (m/s²).
10. What is a periodic table?
Show the answer
The periodic table is a tabular arrangement of chemical elements organized by increasing atomic number.
11. Who is credited with creating the first periodic table?
Show the answer
Dmitri Mendeleev is credited with creating the first widely recognized periodic table in 1869.
12. What is an element?
Show the answer
An element is a pure substance consisting of only one type of atom.
13. What is the atomic number of an element?
Show the answer
The atomic number is the number of protons in the nucleus of an atom of that element.
14. What are groups in the periodic table?
Show the answer
Groups are the vertical columns in the periodic table. Elements in the same group have similar chemical properties.
15. What are periods in the periodic table?
Show the answer
Periods are the horizontal rows in the periodic table. Elements in the same period have the same number of electron shells.
16. What are metals?
Show the answer
Metals are elements that are typically shiny, malleable, ductile, and good conductors of heat and electricity.
17. What are non-metals?
Show the answer
Non-metals are elements that are generally poor conductors of heat and electricity and are not malleable or ductile.
18. What are metalloids?
Show the answer
Metalloids are elements that have properties intermediate between metals and non-metals.
19. What is the chemical symbol for oxygen?
Show the answer
The chemical symbol for oxygen is O.
20. What is the chemical symbol for gold?
Show the answer
The chemical symbol for gold is Au.
