Potential energy is highest at the dead top of the highest point on the roller coaster. It is lowest at the lowest point. Kinetic energy (motion energy) is highest at the point where the velocity is highest. This depends on the design. A good guess is dead bottom of the longest fall, but on a complex coaster ride there are other possibilities. Also, air resistance and friction can change this.

Mach I (the Speed of Sound) is approximately 1,236 km/h (738 mp/h).

This is dependent on the air pressure. At sea level, the speed of sound is about 760 mph; at high altitude it reduces closer to 600 mph.

The kinetic energy of a body is (1/2)mv2, where m is mass and v is velocity. If the velocity were 1/3, then the kinetic energy would be (1/2)m(v/3)2, which is equal to ((1/2)mv2)/9, so when the velocity is decreased by a factor of 1/3, its kinetic energy is decreased by a factor of 1/9.

1km = 0.621371mi

1km/h = 0.621371mi/h

60 kilometers per hour is 37.28 miles per hour.

221.83 mph

My bet is on the bowling ball. At 20000 ft the pull of gravity is only marginally smaller than that of the baseball bat at 2 ft above sea leval. Because both have been lifted to their respective hights giving them potential energy, I would keep out of the way of the ball.

if an engine runs full speed at 1700rpm and is in top gear which is a one to one ratio, then throo at differential ratio of 5.75;1 the outer circumference of the tyres are 131'' what speed would i be doing please. i also have wheels 0f 128'' if you could kindly help me out many thanks

75 kilometers = 246,062.992 feet.

wave frequencys tell us the number of waves there are on that diagram.

A line parallel to the horizontal (time) axis usually indicates that the radial velocity of the object is zero, that is, the object is not moving towards or away from the origin. The object need not be still since it can be moving at any speed in a transverse direction.

Two parallel lines indicate two objects, at different distances from the origin, gthat are moving at the same radial speed.

You would have to maintain a pace of at least 9.54 miles per hour for 6.2 miles.

30 feet per second equals how many kilometers per hour? Solution: There are .3048 meters in 1 foot. Start by multiplying 30 times .3048 = 9.144. There are 1000 meters per kilometer. Then, divide 9.144 by 1000 = .009144. There are 3600 seconds in 1 hour. Finally, multiply .009144 times 3600 = 32.92 (answer!)

At 40 mph you are traveling about 58.667 feet every second.

75 km per second = 14,763,779.5 feet per minute.

296 kph = 183.9 mph

Kinetic energy is the energy a body has because of its mass in motion.

and

Potential energy is the energy a body has because of its position in a gravitational field (- the energy trying to pull it down).

These are two different types of energy but the energy is interchangeable. For instance:-

If you hold a cube of steel 3 feet in the air, it's total energy is its gravitational potential (potential energy).

When you release the cube, this potential energy is converted into movement (kinetic energy).

When it hits the ground it will stop but the kinetic energy will have been dissipated in the form of other energies or mechanical work - sound, some heating of the ground and the object and perhaps a small dent.

Now the object is 3 ft closer to the center of the gravity field and has less potential energy than before (but still has some, it wants to fall further)

Thus the total energy equation is:-

Energy at the start (all potential) = Residual potential energy + kinetic energy of falling (which is = to dissipated energy -sound, heat and dent)

75 mph is approximately equal to 120.7 kilometers per hour.

The relationship between the coefficient of kinetic friction ( denoted as uk ) and the mass, surface area, type of material or the speed of the object, is that the uk between a moving object and a non-moving object affects and distributes it on every points of an atom or molecule in all regions of both of the surface area of the two objects in contact with the object in motion, also the material from the object in motion relatively in contact to the surface of the other object which is not moving at all, determines the speed of the object, whether the material is rough that has lesser speed than that of a smooth surface or smooth vice versa.

when a cold mass meets a warm air mass, it makes weather & any type really; it falls from the cloud where the cold water has frozenD:

Surface energy can be viewed as the amount of work required to move a molecule from the bulk to the surface. So if something has high surface energy, it is has a low propensity to interact with another surface, thus giving it a lower COF.
