Kepler's 2nd Law
This is the name of Kepler's second law, which states that a planet's orbit sweeps out equal areas in equal times.
What is equal areas?
This law, formulated by Kepler, relates the orbital period of a planet to the size of its orbit around the Sun.
What is Kepler's Third Law?
Or
The law of Harmony
According to Newton's law of universal gravitation, as two objects move apart, the gravitational force ________.
What is decreases?
The force of gravity is also known as _______.
What is Weight?
This is anything that accelerates a mass.
What is a force?
According to Kepler's second law, a planet moves fastest when it is at this position with respect to the object it is orbiting.
What is closest?
Kepler’s Third Law shows that the square of a planet's orbital period is proportional to this quantity raised to the third power.
What is orbital radius?
An object with more mass will exert a ________ force on an object when compared to an object with less mass.
What is greater?
This is the amount of matter or "stuff" that something contains.
What is mass?
This refers to the circular motion of a satellite or planet.
What is an orbit?
The shape of a planet's orbit, as described by the eccentricity, ranges from 0 to 1. A perfectly circular orbit has an eccentricity of this value.
What is zero?
According to Kepler's Third Law, this is the only factor affecting the length of a year for any given planet.
What is its orbital radius?
This what is the name of the constant G in the universal gravitation formula?
What is the Gravitational Constant?
Speeding up, slowing down, or changing directions.
What is acceleration?
This is the bending of space-time. First truly described by Einstein in his Theory of Relativity.
What is gravity?
Kepler’s second law implies that when a planet is closer to the Sun in its elliptical orbit, the speed of the planet must do this.
What is increase?
What is 356 days?
or
1 Earth Year
This is the value of the gravitational constant G.
What is 6.67x10-11
This law is known as the law of equal areas.
What is Kepler's 2nd law?
This famous physicist invented calculus, formulated the law of universal gravitation, has a unit of force named after him, and outlined 3 laws of motion.
Who is Isaac Newton?
This term describes the measure of how elongated an orbit is, with a value closer to 1 indicating a highly elliptical orbit.
What is eccentricity?
Kepler's third law states that the orbital period of a planet squared is equal to the ________ of its orbital radius?
What is cube?
This is the formula for universal gravitation.
What is Fg=Gm1m2/r2
This law is known as the law of harmonies, and relates a planet's orbital radius to its orbital period.
What is Kepler's 3rd Law?
This is a value assigned to an orbit that describes how circular or elliptical that orbit is.
What is eccentricity?
