Kinematics

When potential energy changes to kinetic energy, it is called "energy transformation" or "energy conversion."

Whether 2.5 mph is slow or not depends on what is moving.

2.5 mph is about the average human walking speed.

Turkeys are not capable of traveling at speeds of 55 mph. The maximum running speed of a turkey is around 20-25 mph.

315 feet in 45 seconds equates to exactly 7 feet per second.

No, kinematics specifically refers to the study of motion. If an object is at rest, there is no motion occurring, and therefore no kinematics.

62 mph stands for 62 miles per hour, which is a unit of speed commonly used in the United States. It indicates that an object or vehicle is traveling at a rate of 62 miles in one hour.

Yes, horses are capable of running at speeds of up to 40 mph. However, the average speed of a galloping horse is typically around 25-30 mph. The exact speed achieved can also depend on the breed and individual conditioning of the horse.

Winds with a speed within the range of 4 mph to 31 mph are categorized as light to moderate breezes. These winds are typically gentle and can be felt on the face. They are strong enough to move leaves and small branches but do not cause significant damage.

mass x velocity = momentum.

(velocity = speed with a direction)

70kph = 43.496 miles per hour.

Yellow jackets can be found in many different parts of the world. Yellow jackets are fast and can fly up to 14 feet in only nine seconds.

The three point turn which is also referred to as a K-turn, is used when the street is too narrow to make a U-turn. To make the maneuver, drive across the road diagonally and then reversing while turning to go back the other way.

An object which is not changing in it's position in space. In simply it is at rest

About 25.5mph assuming my math is correct: 5280ft/330=16 16x9.68=2min35sec 60mph/2.6min=25.5mph

The above answer is incorrect. This would be true if it was a constant velocity, but because the runners are starting from a stop you need to factor in acceleration. But again we run into a problem because the acceleration is not constant so calculating the final velocity would be a bit tricky. A time of 9.68 the runner would probably be going close to 30mph.

Yes. As the car goes down the hill, the potential energy decreases and the kinetic energy increases. However, not all of the potential energy becomes kinetic energy. Some of it is lost to heat and sound energy.

the largest moving object is a train

I believe the largest man made moving object is a oil tanker called the Jahre Viking which has a dead weight of 564,763 tons and is so big it can't navigate through the English Channel, it carries a cargo close to its own weight. The longest man made moving object was train making a one off train journey in Australia consisting of 8 AC6000 locomotives pulled 682 wagons loaded with iron ore, the train weighed circa 100,000 ton and the cargo weighed about 80% of this weight. The train was 4.6 miles long

The largest manmade moving object on the earth is a oil and gas seismic survey vessel called the Ramform Viking and is produced by PetroGEO Services (PGS). And it collects more than 1.12 Terabytes of seismic survey data per day.

The surveyor with its 10 streamers at 120 m separation is more than a kilometer wide and more than 8 km long covering a surface area of 8.75 km2 at any time. Moving at a speed of 4.3 knots it is covering a total surface area of 215 km2 per day in full production. It represents the largest moving object on the face of the earth, bigger than any seismic spread ever deployed and bigger than anything else moving on land or at sea.

By definition, illegal immigration is migration of people across national borders in a way that violates the immigration laws of the destined country. The goal is generally upward mobility.

Illegal Immigration is common in areas such as the United States, Britain, France, and most of the well known Western world (Including Germany, to name a few)

Illegal Immigration is common include Japan, South Korea, and Australia.

Illegal Immigration often involves criminal syndicates. Russian & Italian Mafia in the Western World and the Chinese Triads are in main control in the Far East.

In the United States, the majority of illegal immigrations involve the Chinese Triads (Pacific), the Russian/Italian Mafia (East Coast), and Mexican Cartels (South)

The potential energy of an object is given by the formula PE = mgh, where m is the mass, g is the acceleration due to gravity, and h is the height. Plugging in the values of m = 100 kg, g = 9.81 m/s^2, and h = 10 m, we get PE = 1009.8110 = 9810 J. So, the potential energy of the 100 kg mass 10 meters above the ground is 9810 Joules.

inc temp, increases the ave. KE of the particles.

116 kmh in equivalent to 72 mph or 32.2 metres/sec.

Kinetic Energy = 1/2 mv2 where m = mass and v = velocity A train has much more mass than a car. So even if they are travelling at the same speed, a train will have more kinetic energy than a car.

Yes, the angle at which two objects collide can affect the force of impact. In a collision, the force of impact is dependent on both the angle and the velocity of the objects involved. A head-on collision, for example, will generally result in a higher force of impact compared to a glancing blow at an angle.

Depends on the details of the question.

There is a technical limit set by bike/rider interaction, what gearing ratio, wheel size etc the bike has, and how fast the rider can turn the pedals.

Assuming an average bike build and average pedaling skills, you get a top speed around 25-28 mph(40-45 kph) before "spinning out", the speed where the pedals turns too fast for the rider to be able to add any more power.

Now, doing 25 mph on a mtb is quite taxing. Wide, knobbly wheels, upright riding position etc. There's a lot of air drag and rolling resistance.

On uneven, soft surfaces it becomes even worse.

A realistic average is about half.

But maybe you're descending a hill. Hitting 40 mph (64 kph) downhill is easily doable.

On courses designed for speed, riders can go considerably faster, say 70-80 mph on gravity alone.
