100
Metric system units are always based on powers of this number
What are powers of 10
100
m/s^2
What is the unit for acceleration?
100
The acceleration of a ball when the force of gravity = -5N and the force of air resistance = 5N.
What is 0m/s^2?
100
Instead of increasing velocity, kinetic energy can also increase when this is larger.
What is mass?
100
Thermal energy depends on these three variables.
What are mass, temperature, and specific heat?
200
It is the fuel source with the highest energy density.
What is nuclear energy?
200
The slope of a line on a distance-time graph.
What is speed?
200
The object that exerts the greatest gravitational force on you.
What is the Earth?
200
The kinetic energy of a ball with a mass of 0.6kg moving at 50m/s.
What is 750J?
200
We put this kind of substance inside the walls and under the roofs of buildings because it conducts heat so poorly.
What is an insulator?
300
The quantity of matter in an object
What is mass?
300
Speed and a direction.
What is velocity?
300
Objects accelerate in the same direction as this.
What is the net force?
300
The gravitational potential energy of an 80kg diver 5m above the water.
What is 3920J?
300
It is how the thermal energy of a closed system changes over time.
What is constant?
400
The amount of space an object occupies.
What is volume?
400
It is when velocity changes.
What is acceleration?
400
Weight, friction, and air resistance are all examples of it.
What is force?
400
The force a person exerts in pulling a wagon 20m if 1500J of work is done.
What is 75N.
400
Thermal energy consists of these two kinds of energy.
What are heat energy and potential energy?
500
Kilograms, Liters, meters, and Joules are examples of these (hint: they have a francophone acronym)
What are SI units?
500
A sprinter's final speed 3s after accelerating at 4m/s^2.
What is 12m/s?
500
It is the fundamental equation described by Newton's second law of motion.
What is F=ma?
500
The ideal mechanical advantage of a ramp that is 6m long on the diagonal and 2m high.
What is 3?
500
The specific heat of 0.5kg of metal that absorbs 9000J of thermal energy as it warms by 10 degrees C.
What is 1800 J/(kg x degrees C)?
