v in m/s
What is speed/velocity measured in meters per second?
100
This is the information required to calculate work.
What is force used and distance moved?
100
This law of motion states that any given object will remain in motion at a constant velocity or at rest unless acted upon by an unbalanced force.
What is Newton's First Law of Motion?
100
This is the formula needed to calculate momentum.
What is p=mv (mass * velocity)?
100
This law of thermodynamics states that disorder, or entropy, in a system can only increase.
What is the second law of thermodynamics?
200
p in kgm/s
What is momentum measured in kilogram-meters per second?
200
Energy of position, measured in joules, calculated by multiplying an object's mass, height from a starting position, and gravitational acceleration.
What is gravitational potential energy?
200
This is any change in velocity (direction, speed, or both) as a result of the action of an unbalanced force.
What is acceleration?
200
This is defined as any change of momentum, and can be measured in either Ns or kgm/s.
What is impulse?
200
This is the only form of heat transfer that can take place across the vacuum of space.
What is radiation?
300
E/W in J
What is energy or work measured in joules?
300
This is the type of energy an object dropped from a height would have just before it hits the ground.
What is kinetic energy?
300
This is the law of motion demonstrated by the following scenario: the direction of an unbalanced or net force upon an object matches the direction of its acceleration.
What is Newton's Second Law of Motion?
300
This is the amount of impulse (in Ns) necessary to cause a change of momentum of 50 kgm/s for a 10 kg object.
What is 50 Ns?
300

What is current in amps?
400
This is the amount of power needed to hold an object motionless above the ground for 30 seconds.
What is 0 watts?
400
This is the net force acting on a falling stone weighing 15 N which encounters 8 N of air resistance.
What is 7 N? (15 N - 8 N)
