Force and mass are relative to this.
What is Acceleration?
The story over this fruit was entirely made up; Newton didn't get hit by it but instead was looking at it's tree at a distance.
What is an apple?
(G) Force of object to another object that has mass (7)
What is gravity?
Temperature
What is Kelvin?
Scientists found this planet not by seeing it with a telescope, but by using Newton's law of gravity to find it.
What is Neptune?
The force of objects sliding against each other.
What is Friction?
Newton was appointed the title of "Warden of the Royal Mint" (like the secretary of the treasury) in this country.
What is the United Kingdom?
(G) A musical instrument that has six strings and makes sound by vibration (6)
What is a guitar?
Mass
What is gram?
Albert Einstein transformed the world with his theory of general relativity by theorizing that this massive object with a big gravitational force could exist.
What is a black hole?
Newton's discoveries over motion and gravity exposed the mystery behind this, another name for the rise and fall of water, which proved that the cause was the moon and sun's gravitational force.
What are tides?
What is Christmas?
(C - E) Force that accelerates around a centre (16)
What is centripital force?
Force/Weight
What is Newton?
The bullet train isn't a train at all; it doesn't use friction, but uses this force, relative to all objects that have mass, to accelerate.
What is gravity?
Modern physics delves into quantum mechanics, which started with Max Planck's Quantum Theory and this scientist's Theory of Relativity.
Who is Albert Einstein?
Newton spent a lot of time on alchemy, which then evolved into this scientific study of atoms and molecules.
What is chemistry?
(W) The measurement of gravitational pull downwards of an object (6)
What is Weight?
Temperature based on Kelvin and is used in the U.K.
What is Celsius?
Another force similar to drag is this, which resists an object from moving by air. Aerospace engineers use propellers to resist drag, as to fly faster.
What is air resistance?
Mass and velocity are two factors in creating this measurement of motion.
What is momentum?
Newton believed that a substance called the Philosopher's Stone, (not the one from Harry Potter) could turn any metal into this shiny mineral.
What is gold?
(M) the amount of motion an object has (8)
What is momentum?
Measure of volume not associated with SI but can be used with SI units
What is Litre?
Newton invented this mathematical study of change which is used everywhere in science and math.
What is Calculus?
