Part 1: Newton's 1st and 2nd Laws
An object will remain in motion or at rest until another force acts upon it. (Example: a ball will continue rolling until a force, such as a child, picks the ball up.)
What is Newton's First Law of Motion?
I am a region of space; a measurable gravitational force can be indicated by the force exerted on a test mass.
What is a gravitational field?
I'm the quotient of velocity divided by time.
V/T = ?
What is acceleration?
For every action, there is an equal and opposite reaction.
What is Newton's 3rd Law of Motion?
I am an Egyptian astronomer who developed the geocentric theory.
Who is Ptolemy?
Force is the product of mass multiplied by acceleration.
F = ma
What is Newton's 2nd Law of Motion?
I am an attractive force; the reason for this is b/c of the presence of another mass. I'm actually a very weak force (only 6.67 x 10^-11 N(m^2)/kg^2).
What is an attractive force?
I'm the acceleration of an object traveling in a circular path.
? = v^2/R
What is centripetal acceleration?
(momentum before) = (momentum after)
(mv/t) = (mv/t)
What is the Law of Conservation of Momentum?
I am a Polish astronomer who developed the heliocentric theory.
Who is Nicholas Copernicus?
The product of the force of an object and the time of contact
I = ft
What is impulse?
Gravitational forces vary inversely as the square of the distance of separation.
F~ m1m2/d2
What is the Inverse Square Law?
I'm a center-pointing force.
F = m(v^2/R)
What is centripetal force?
I didn't agree with either the Ptolemaic or Copernican system, so I developed my own. I call it the Tychonic system, and it makes a compromise between both theories.
Who is Tycho Brahe?
The product of an object's mass and its velocity
P = mv
What is momentum?
I differ, depending on the gravitational force on planets. I am the product of mass and acceleration due to gravity.
mass(acceleration due to gravity) = ?
What is weight?
Use this formula to find me.
v^2 = Gm/R
What is the velocity of a satellite?
I am an Italian scientist who has been branded as a Catholic heretic and forced under house arrest ... all because I believe in the heliocentric theory. "And yet it moves" is my most famous quote. I'm usually known by my first name.
Who is Galileo Galilei?
He came up with the idea of gravity and developed three laws of motion. He was born in 1642 and died in 1727. He was a strong Christian scientist, and he was knighted by Queen Anne.
Who was Sir Isaac Newton?
Again, it depends on what planet/moon I'm on. I'm approximately 9.8 m/s^2 or 32 ft/s^2 on Earth. I'm 1.6 m/s^2 on the moon.
What is acceleration due to gravity?
a^2 + b^2 = c^2
a geometric formula
What is the Pythagorean Theorem?
I believe in galileo's theories on the heliocentric theory. Here are three laws of planetary motion.
(1) The planets travel in elliptical orbits.
(2) The closer a planet gets to the sun, it faster it revolves.
(3) R^3/d^2
Who is Johannes Kepler?
