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?
The variable we control.
What is the independent variable?
Energy when something is in motion.
What is kinetic energy?
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?
The variable we measure.
What is the dependent variable?
The unit we use to measure length.
What is a meter?
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?
This type of material allows electrons to flow through easily.
What is a conductor?
A general force when we don't know what's causing the push or pull.
What is an applied force?
A statement made before starting measurements about the expected relationship between the two variables, including a reason.
What is a hypothesis?
This is when an object is speeding up, slowing down, or changing direction.
What is acceleration?
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 law allows us to calculate the electrical force between two charged objects.
What is Coulomb's Law?
A force that resists motion, often caused by something sliding on a rough surface.
What is the force of friction?
A relationship between two variables where one increases and the other increases.
What is a direct relationship?
This is defined as the change in momentum.
What is impulse?
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?
Heat transfer due to the movement of fluids.
What is convection?
A force perpendicular to a surface that pushes back on an object.
What is the normal force?
A relationship between two variables where one increases and the other decreases.
What is an inverse relationship?
Another word for this is "potential difference."
What is voltage?
