Kinematics
Kinematics is the study of how a body moves. This includes linear motion, angular motion, and rotational motion.

If the density of the solid body is greater than the density of the liquid the body
will sink. If the density of the liquid is greater than the density of the solid the
body will float.
If the solid and the liquid have the same density, the solid body can be any where
inside the liquid and may move following currents if they exist in the liquid.

Most of elevator's potential energy was transferred to its massive
counterweight, which was lifted high up in the shaft as the elevator
descended. Some of its energy was dissipated in both heat and noise.
Also, don't forget about the kinetic energy that the car had while it was
moving. Most of that was absorbed by either a mechanical brake, or else
by the motor that's usually replacing the energy lost from the system.
How do to solve these kinematics question?
An inspection of these equations shows that there are clear mathematical.
What is the formula to convert gallons per hour to liters per second?
(1 US gallon/hour) x (1 hour/3,600 seconds) x (3.78541 liters/US gallon) = 0.0010515liter/second

Is Gravitational potential energy a type of kinetic or potential energy?
Gravitational potential energy is a type of potential energy that is associated with an object's position in a gravitational field. It represents the energy stored in an object when it is raised to a certain height above the ground.
What is The GMC Typhoon's Top Speed?
A stock GMC Typhoon is governed by the ECU and will not exceed 124 MPH.
The land speed record for a motorcycle is 350.88 mph. The Suzuki Hayabusa claims to be the fastest current production motorcycle at just under 190mph off the assembly line.
You cannot. You need to know either the initial speed or angle of projection (A).
Why the displacement time graph is parabola?
The nature of displacement-time graph is parabolic if the acceleration is constant(uniform).
When acceleration is constant, displacement is directly proportional to the square of time which results into a parabolic structure of graph.
What will be the tension in a rope that is pulled from its ends by to opposite forces100 N each?
Assuming you meant two forces, the tension will be 200N.
231m
Why cars do not have linearly increasing acceleration?
There are 2 main reasons, first is that with every up-shift of the transmission the mechanical advantage of the gearing lowers.( example: riding up hill on a 10speed bike in 1st gear vs.10th gear, 1st is easier.) The second reason is that wind resistance increases 4times when the speed doubles. (example: sticking your hand out the window of a car going 20mph vs. when the car is doing 100mph and you'll feel the difference.)Wind resistance is main limiting factor for top speed o most sports cars.
A scalar measurement is one that requires only one number. For example, my mass is 82 kg. BUT some measurements require more than one number to specify. For example, a force on me has both a magnitude and a direction. Such things are called "vectors." Speed is a scalar quantity. I am going 35 km/hr, but velocity is a vector, which requires a magnitude, which is the speed, AND a direction. So my speed is 35 km/hr, but my velocity is 35 km/hr east.
Is wind up for the pitch kinetic energy or potential energy?
Answer 1
Kinetic. Remember, kinetic energy is the energy of movement.
Answer 2
If one considers winding up for the pitch as analogous to winding up the spring on a crossbow, then you are converting kinetic energy (the motion produced by your arms) to potential "elastic" energy. Releasing the catch on the bow then converts the stored potential energy to the kinetic energy of the bolt as it flies away.
Of course people are not crossbows, and the interplay of forces and motions is a bit more complex.
Added:
Answer two's analogy is flawed as the potential energy on the cross bow winding is not potential until the mechanism is stopped and locked. Until that point the energy is kinetic to potential. A pitcher winding up does not store potential energy as a locked in place cross bow bolt does.
Added 2:
Hence my statement that winding up a crossbow is *converting* kinetic energy to potential, while releasing the crossbow *converts* potential to kinetic energy.
But as already noted, comparing winding up for a pitch to winding up a crossbow is probably not very accurate anyway.
When a pitcher winds himself up for a pitch, he positions himself in such a way as to be able to convert the maximum amount of *chemical* energy into kinetic energy. At least, that's how I see it.
The exact conversion to KPH is 36.05. If that's the answers your question.
What is the net force if the horizontal force is 150n?
There is not enough information to answer this question.
You can do it !
Take one of the words on your list, and go through the alphabet. You'll hit some real words that
you can use for rhymes, of course along with a lot of duds. But rhyming lines will come into your head.
Take "flight" ... you already have a rhyme on your list ... "height". Go through the alphabet and get more:
A, bite, C, D, E, fight, G, height, I, J, kite, light, might, night, O, P, quite, right, sight, tight, U, V, white, X, Y, Z.
And don't forget appetite, contrite, and plight.
And guess what else ! Not only CAN you do it ... you HAVE TO do it ... because nobody else,
least of all me, is going to do it for you, no matter howuncreative you are !
How do you calculate area under the acceleration time graph?
The mathematical technique used to calculate the area under a graph is integral calculus. This is a complex subject which I am not going to attempt to explain in detail- it normally takes years of study.

What type of energy does a sled have as it slides down a hill?
While a sled slides down a hill, it has kinetic energy(Ek = 1/2mv2).
At the top of the slope, while not moving, it would have possessed gravitational potential energy. As it moves down the slope, however, some energy is converted to heat and sound in accordance with the Law of the Conservation of Energy which states that matter cannot be created or destroyed but is converted from one form to another.
