Motion
It's the value of the acceleration of all objects in free fall on Earth. Don't forget the units!
How much is 9.8 m/s²?
It's a law that states that every object continues in its state of motion until an unbalanced force acts on it.
What is the Law of Inertia?
(or Newton's First Law)
It's the force that exists due to the contact of any two objects, due to the imperfections in each surface. This is the force we use to walk and it's the reason why everyday objects stop moving eventually.
What is friction?
It's the official unit of energy, used to simplify kg.m²/s².
What is a Joule?
It can't shoot arrows like the others but I can be seen in the sky on occasion.
What is a rainbow?
It's the magnitude of an object's velocity when it's thrown vertically up and it reaches the highest point in its trajectory.
How much is zero?
It's a law that state that every force applied to an object will result in an equal and opposite force applied reciprocally, to the object that applied the first force.
What is the Law of Action and Reaction?
(or Newton's Third Law)
It's the name of the force that exists in ropes or strings. Used a lot in multi-body systems.
What is Tension?
It's the energy related to the amount of motion of an object.
What is kinetic energy?
It's the king you can make if you take
the head of a lamb
the middle of a pig
the hind of a buffalo
and the tail of a dragon
What is a lion?
It's a physical quantity that determines the change in velocity over time. In other words, it determines if the motion becomes faster or slower. It's the actual reason why high-speed sports like Formula 1 are so dangerous.
What is acceleration?
It's the type of friction that exists in objects that are at rest. It's higher than the other type.
What is static friction?
(or just static)
It's a force applied by any surface, like the force the table applies on a book on top of it. It's always at a 90º angle with the surface, no matter if the surface is horizontal, vertical, or inclined.
What is normal force?
It's the energy related to the capacity of motion of an object that it's not yet being used.
What is potential energy?
I turn hot at the color red
If you don't get out of the way, you'll soon be dead
But if you hit me square in the eye, you'll have won
Can you guess what I am, before you're done?
What is a bulls eye?
It's physical quantity determines how fast or slow a motion is. It's calculated by dividing the distance traveled by the time needed to travel that distance. It does not account for the direction of the motion.
What is speed?
(or average speed)
It's the only physical quantity that always results in a change in motion in an object.
What is the net force?
(or unbalanced Force - but just force is incorrect)
They are the two physical quantities used to calculate friction force.
What are the coefficient of friction and normal force?
It's the physical quantity that causes a change in the amount of energy of an object.
What is work?
A word I know,
six letters it contains
subtract just one,
and twelve is what remains.
What are dozens?
It's what you calculate in a velocity vs. time graph to find the motion's acceleration.
What is slope?
(or derivative, but come on...)
It's the object's amount of inertia. It determines how much an object will accelerate when it receives an unbalanced force.
What is mass?
They are the two physical quantities used to calculate elastic force or the force of a spring.
What are Elastic Constant and Deformation?
(the words don't have to be perfect... just saying constant, stretch, or anything similar works)
They are the physical quantities used to calculate the gravitational potential energy of an object.
What are mass, acceleration of gravity, and height?
(it's okay if "acceleration of" is not said)
Always old, sometimes new.
Never sad, sometimes blue.
Never empty, sometimes full.
Never pushing, always pulling.
What am I?
What is the Moon?
