Famous Physicists
Legend has it this scientist discovered the force of gravity when an apple fell on his head.
Who is Sir Isaac Newton?
This property of matter can be either positive or negative.
What is charge?
The force that keeps us on Earth and not floating off into space.
What is the force of gravity?
This is always conserved in a collision.
What is momentum?
This is the length of the AP Physics 2 exam.
How long is 3 hours?
He is famous for his General Theory of Relativity and the equation e = mc2.
Who is Albert Einstein?
The Greek letter delta (triangle) means this concept in physics and math.
What is change?
A force caused by pulling on a string.
What is the force of tension?
This has to be zero for energy in a system to be conserved.
What is work?
These are the two sections on the exam.
What are the Multiple Choice and Free Response sections?
His studies supported the idea that the Earth revolves around the Sun. He famously dropped metal balls off the Leaning Tower of Pisa.
Who is Galileo Galilei?
A closed path in which electrons flow from a voltage source.
What is a circuit?
A force that resists motion, often caused by something sliding on a rough surface.
What is the force of friction?
These two types of energy make up mechanical energy.
What are kinetic energy and potential energy?
This is the approximate percent of points you need to get to score a 5 on the exam.
What is 72%?
She was the first woman to win a Nobel Prize, and the first person to win one in two different sciences (Physics and Chemistry).
Who is Marie Curie?
This is charge per time.
What is current?
A force perpendicular to a surface that pushes back on an object.
What is the normal force?
This is only conserved in an elastic collision (and is not conserved in an inelastic collision).
What is kinetic energy?
This is the approximate percent of points you need to get to pass the exam (with a 3 or higher).
What is 41%?
One of the 20th century's most influential physicists, he played a key role in the discovery of quantum electrodynamics, the theory that describes how light and matter interact.
Who is Richard Feynman?
When the crest of one wave overlaps with the crest of another wave.
What is constructive interference?
A type of force that brings a system back to equilibrium (an example is the spring force).
What is a restoring force?
Conservation of this quantity is a direct result of Newton's 3rd Law.
What is momentum?
The date of the AP Physics 2 exam this year.
What is May 7, 2021?
