Kinematics
(Motion)
(Motion)
It's physical quantity determines how fast or slow a motion is. It's calculated by dividing the distance travelled by the time needed to travel that distance. It does not account for the direction of the motion.
What is speed?
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 amount of complete rounds per unit of time, measured in Hertz (Hz).
What is frequency?
It's the force applied to an object for a period of time. It's measured in Newtons-seconds (Ns)
What is impulse?
What is a rainbow?
It's a physical quantity that determines the change in speed over time. In other words, it determines if the motion became faster or slower. It's the actual reason why high speed sports like Formula 1 are so dangerous.
What is acceleration?
It's a law that states that every objects 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 one of the factors the influence the strength of the gravitational force between two objects. The more of it, the less gravitational force there is.
What is distance?
What is momentum?
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 determines how fast or slow a motion is. It's calculated by dividing the displacement of an object by the time needed. It takes into account the direction of the motion as well as its values.
What is velocity?
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 one of the factors the influence the strength of the gravitational force between two objects. The more of it, the more gravitational force there is.
What is mass?
Those are the forces that don't cause an impulse on a system due to Newton's Third Law of Motion.
What is internal forces?
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 composed of three dimensions: length, height, and width. It's also a word used to represent the outside of our planet.
What is space?
It's the force caused on objects by the gravitational attraction to the Earth. People commonly talk about it in kilograms (kg) even though it's not actually correct since it's a force and not mass.
What is weight?
It's the period of a circular motion with a frequency of 1000 Hz.
What is a millisecond?
(or 0.001 seconds)
It's the consequence of an impulse applied to any object.
What is change in momentum?
I am a protector.
One person can see right through me, while others wonder what I hide.
What are sunglasses?
It's considered the fourth dimension in our universe, in which we are trapped always moving to the same direction.
What is time?
It's a force applied by any surfaces, like the force the table applies on a book on top of it. It's always in a 90º angle with the surface, no matter if the surface is horizontal, vertical or inclined.
What is normal force?
It's the linear speed of a circular motion with a frequency of 2 Hz and a radius of 5 meters.
What is 60 m/s?
(or 20π m/s)
It's a collision in which the objects deform but come back to normal completely, resulting in a conservation of energy as well as of momentum.
What are elastic collision?
If you throw me from the window,
I will leave a grieving wife.
Bring me back, but in the door, and
You'll see someone giving life!
