Out of these statements, number ____ is false.
1. Gas particles are in constant random motion.
2. Freezing points only happen at low temperatures.
3. Adding heat causes particles to speed up.
#2 is false. Freezing can happen at any temperature, it just depends on the substance and other conditions.
100
This state of matter has a definite volume, but not a definite shape.
What is a liquid?
100
An open parachute works to slow someone because it increases the surface area for air resistance to work on. True or false?
True
100
If a marble was dropped from table height, and at the same time another marble was rolled off of the table, which would hit the ground first?
"Trick" question; they would hit the ground at the same time.
100
If something is traveling a distance of 40 meters in 20 seconds, what is it's speed?
2 m/s
200
These are the particles that can be found in the nucleus.
What are protons and neutrons?
200
What can we add to a "system" to increase the number of collisions?
Heat, energy, particles, pressure, etc.
200
Give an example of an action and reaction force.
Determined by teacher.
200
This is the direct line from point A to point B.
What is displacement?
200
50 kg 2 m/s
^mass ^speed(velocity)
Momentum = 50 kg * 2 m/s
Momentum = 100 kg*m/s
300
The elements in the periodic table are sorted by increasing _________
Atomic number
300
What does endothermic mean? What about exothermic?
Heat is added to the system (heat enters)
Heat is given off by the system (heat exits)
300
What is the force that causes you to continue moving once the brakes on a car have been engaged?
Inertia. Inertia is a resistance to a change in motion.
300
If both have the same momentum, would a golf ball or a bowling ball be moving faster? Why?
We know they have the same momentum, so if the bowling ball has a higher mass, it's going to have a smaller velocity (speed).
300
900 Newtons, 750 kg.
^force ^mass
900 / 750 = a
1.2 = a
400
If an atom has a mass number of 53 with 18 neutrons, what is the atomic number?
53 - 18 = 35 protons
400
Draw and label the phase change diagram.
(The triangle involving the states of matter)
400
These are the forces involved in projectile motion.
What is the initial forward velocity and the downward force of gravity. Bonus if you included air resistance! :)
400
If I walk 10 blocks west, then 8 blocks south, then 17 blocks west, then 24 north, then 40 east, then add all the blocks I walked together, what would I be calculating?
What is the distance traveled?
400
If an object moved 100m in 4s, then remained at rest for 1s, what was its average speed?
20 m/s
500
How many neutrons are in this element?
500
List 5 physical properties and 2 chemical properties/phenomena.
Decided by me :)
500
Name as many of the friction types we discussed that you can remember.
Sliding, Static, Rolling, Fluid
500
A car coming up to a stop time changes speed from 35 mph slowly to zero in 10 seconds. How can the car's acceleration be described over this time?
The car had negative acceleration/deceleration.
500
If an object takes 10 seconds to come to a stop from 60 m/s, what is its acceleration?
-6 m/s2
