This is what you get when you divide the distance traveled by the time taken to travel it
What is speed
100
These are two examples of a solution and these are two examples of a mixture.
What is instant coffee powder in water, or ice tea mix in water are both solutions, what is a fruit salad or a salt and pepper combined are mixtures
100
This is what happens to particles of water when heated
What is they have more space between them
100
Sound energy travels fastest in this type of medium (medium being solid, liquid, or gas)
What is solid
100
This what like poles of a magnet do and this is what unlike poles of a magnet do.
What is like poles repel and unlike poles attract
200
This is the rate of change of velocity
What is acceleration
200
These are examples of physical changes and these are examples of chemical changes
What is rain turning to sleet, ice melting to water, food dye coloring a prepared cake, pounding piece of copper to a sheet are all physical changes. Baking a cake from mix, burning a log in the fireplace, dissolving an antacid tablet in water, vulcanizing rubber are all chemical changes
200
This is the type of heat transfer that warms greenhouses
What is radiation
200
This is potential energy and this is kinetic energy
What is potential energy is stored energy, which does not cause any immediate change but can cause change in the future. Kinetic energy is energy of motion.
200
Of the following material this is the one that will slow down the flow of electric charge the most a. iron, b. water, c. pencil lead, d. wood
What is d.
300
If you are braking your bicycle, this is the force used to change the motion of the bicycle
What is friction
300
These are the types of chemical reactions describing the following a. AB + CD --> AC + BD b. ABCD --> A + B + C + D c. AA + BB --> AB + AB
What is a. replacement, b. decomposition, c. combination
300
This is the amount of matter contained in a body and this is the space it occupies
What is mass and what is volume
300
In a pendulum this is the point which has the highest kinetic energy and this is the point which has the highest potential energy.
What is the vertically down (highest KE) and two top positions (highest PE)
300
This is how a electromagnet differs from a regular magnet
What is the electromagnet can be switched on and off a regular magnet cannot.
400
This is the one with most force a. 5 kg mass moving 10 m b. 5 kg mass moving 20 m c. 10 kg mass moving 10 m d. 10 kg mass moving 20 m
What is d
400
This is one way chemical technology has improved transportation
What is vulcanization makes all weather rubber. This helps make better tires for cars
400
These are the three types of heat transfer mechanisms
What are conduction, convection, and radiation
400
In a roller coaster this is the position which has the highest kinetic energy and this is which has the highest potential energy
What is the bottom of the highest hill has the highest KE and highest hill point of the track has the highest PE
400
This is what happens when the switch is open in an electrical circuit and this is what happens when the switch is closed.
What is open switch leads to stop the flow of electric current and closed switch leads to flow of electric current.
500
These are the units of distance, mass, force, and work in the metric system.
What is meters, kilograms, newtons, and joules.
500
This is how a salt pepper and water mixture can be separated
What is filter mixture to separate pepper. Then boil salt water to evaporate water and separate salt.
500
These are the three phases of matter which transform into each other when heated or cooled
What are solid, liquid, and gas/vapor
500
This is what both potential and kinetic energy combined is called. In any given situation this is what happens to the total energy.
What is thermal energy. Energy is conserved - it is neither created nor destroyed
500
This is what an electrical circuit with a single path is called and this is what a circuit with multiple paths is called.
What is a series circuit and what is a parallel circuit
