This quantity is equal to mass times acceleration.

What is force?

100

The energy possessed by an object because of its motion.

What is kinetic energy?

100

The unit used to measure electric current.

What is the ampere (amp)?

100

I formulated the three laws of motion and the law of universal gravitation.

Who is Sir Isaac Newton?

100

9.81

What is the approximate acceleration due to gravity on Earth (in meters per second squared)?

200

An object moving at constant velocity has this net force acting on it.

What is zero net force?

200

The SI unit of energy.

What is the joule?

200

This law relates voltage, current, and resistance.

What is Ohm's Law?

200

I developed the theory of special and general relativity. In the modern day, my last name has become synonymous with genius.

Who is Albert Einstein?

What is the speed of light in a vacuum (in meters per second)?

300

According to Newton's Third Law, every action force has one of these.

What is an equal and opposite reaction?

300

Work is equal to force multiplied by this quantity.

What is distance (in the direction of the force)?

300

A resistor with resistance 6 Ohms carries 2 amps of current. This is the voltage.

What is 12 V?

300

I discovered electromagnetic induction and have a constant named after me in electrochemistry despite having received little formal education. 

Who is Michael Faraday?

300

6.022e23

What is Avogadro's number (in particles per mole)?

400

A 10 kg object accelerates at 3 m/s^2. It has this net force.

What is 30 N?

400

An object with mass 2kg moves at 4 m/s. It has this kinetic energy.

What is 16 J?

400

The direction of conventional current is defined as the flow of this charge.

What is positive charge?

400

I developed the uncertainty principle, stating that position and momentum cannot both be known exactly at the same time.

Who is Werner Heisenberg?

400

6.67e-11

What is the universal gravitational constant (in newtons times meters squared per kilogram squared)?

500

A 20 N force pushes a 5 kg object. Ignoring friction, the object has this acceleration.

What is 4 m/s^2?

500

A 5kg object is lifted 10 m on Earth (g ~ 10 m/s^2). This is the gain in gravotational potential energy.

What is 500 J?

500

Two 4 Ohm resistors are connected in series. This is the equivalent resistance.

What is 8 Ohms?

500

I proposed that energy comes in discrete packets called quanta and won the Nobel Prize for work that launched quantum theory.
