Is a book falling down from a high shelf kinetic or potential energy?

It's neither. It's just a piece of fruit.

While it's hanging and not moving, it has gravitational potential energy because of its position,

and food potential energy because of its chemical composition.

When it separates from the tree and moves to a different location, such as the ground or a

processing plant, it has kinetic energy because of its motion. Its chemical potential energy

doesn't change until it's processed, consumed, or rotted.

What would cause kinetic energy to increase?

The kinetic energy, Ek, of a body of mass, m, travelling at a speed, v, is given by;

Ek = 1/2 mv2

Ek can be increased by either increasing the mass of the object (but the additional mass must also travel at speed, v), or by increasing its speed. It is normally more practical to increase the speed of the object.

What happens to an object when it undergoes acceleration is it the speed or velocity that increases?

When an object undergoes acceleration, it is the velocity that increases. Acceleration is the rate of change of velocity, so an object experiencing acceleration will have its velocity change over time, either by speeding up, slowing down, or changing direction.

What is the SI unit of kinematic viscosity?

Kinematic viscosity is the ratio of dynamic viscosity to density of the fluid. The SI unit of the quantity is square meter per second (symbol m²/s). The most frequent used unit of kinematic viscosity is Centistokes (cSt). 1 Centistokes (cSt) is the kinematic viscosity of a fluid with dynamic viscosity of 1 cP and volumic mass 1 g/cm³.

How many blades are on the Gillette Mach 3?

The Gillette Mach 3 is a line of safety razer blades manufactured by Gillette that was introduced to the market in 1998. The razer blade has 3 blades for shaving.

How fast in mph is 180kmh?

111.85 mph After this speed you will have to pay big bucks in France for speeding (up to 1500 euros). The on the spot is 135 Euros until that point

How much is 100 mph in km?

1km = 0.6213712 miles

100 x 0.6214

62.14 miles

100 kph = 62.14 mph
100 kph = 62.12 mph
62.1371192 mph
Since 1 kilometer per hour = 0.621371192 miles per hour, 100 kilometer per hour would = 62.1371192 miles per hour

How fast is 128 kph in mph?

78 kph about 50 mph (48.466953 mph to be more precise!)

NB. kilometres/kilometers divided by 1.609344 equals miles.

For list of commonly requested unit conversions, see 'Related links' below.

What is 14kph in mph?

4/1.6= 2.5 MPH
2.48548477 miles per hour ==

  • 1 mile is 1,6 km.
  • So 4/1.6 = 2.5
  • So 4 KMH = 2.5 MPH

Can a body moving with uniform speed have variable velocity?

Yes it can.When a body moves in a circular path keeping its speed uniform then it will have variable vilocity as vilocity is the speed in a particular direction and while moving in a circular path its direction keeps changing and so does vilocity

What do the letters MPH CHES stand for after a name?

MPH stands for Master of Public Health, a graduate level degree focusing on public health practice and research. CHES stands for Certified Health Education Specialist, an individual certified in the field of health education and promotion. These credentials demonstrate a person's expertise and qualifications in public health and health education.

How fast is 345 fps in mph?

330 fps is 330 feet per second. Mph is miles per hour, so convert your units.

330 ft * 1 mi / 5280 ft = 0.0625 mi

1 sec * 1 hr / 3600 hr = 0.000278 hr

0.0625 mi / 0.000278 hr = 225 mi / hr

What kind of products do the online store mph Online sell?

The online store MPH Online sells all kinds of things ranging from books to games. The online store has a lot of discounts on all kinds of products which makes a very good online store to buy products from.

How many mph is 4.3 seconds for 40 yards?

To convert a time in seconds to miles per hour, you first need to convert the distance to miles. 40 yards is approximately 0.02273 miles. Then, you can calculate the speed by dividing the distance by the time in hours. For 4.3 seconds over 40 yards, the speed is approximately 1.25 mph.

How fast can a human swim in mph?

It depens, how long you've practice swimming. If you've swamm for years, you would probably swimm for aproximily 15 miles per hour. If you've only swamm for 1 year or less, you would swimm about 10 miles per hour or less.

^^ Joke answer right? The world record is like 5mph. The avg experienced swimmer probably 2 mph maybe 3. 3-5 kph. That's a guess, but a better answer than what's above.

What is broaching mach?

Broaching is a machining process where a cutting tool with teeth removes material from a workpiece. It is commonly used to create slots, keyways, and other intricate shapes in metal parts. Broaching is known for its ability to produce highly precise and accurate results.

What is the potential energy of 3.0kg object at the top of a hill 10.0 hihg as measured from the ground?

PE = m•g•h, where m is mass in kg, g is 9.8m/s2, and h is height in meters. I am going to assume that the unit for the height of the hill is the meter. PE = 3.0kg x 9.8m/s2 x 10.0m = 290kg•m2/s2 = 290N•m = 290 Joules

What is the average speed of a particle with a distance of 30km in 1hour?

The average speed of the particle is 30 km/h. This is calculated by dividing the distance traveled (30 km) by the time taken to travel that distance (1 hour).

What does mach 3 mean in aeronautics?

Mach 3 refers to traveling at a speed three times the speed of sound. In aeronautics, Mach numbers are used to compare the speed of an object to the speed of sound in the medium through which the object is traveling. Mach 3 is considered to be supersonic speed.

How fast in mph does Apollo Ohno go on speed skates?

Speed skaters can do average speeds at close to 30 mph. Some of the top athletes such as Apollo Ohno are said to even get up to speeds as fast 35 mph.

How many mph is 19 knots?

There are 1.609344 kilometers in a mile. Therefore 9 kilometers per hour would be 5.6 miles per hour.

What is 65 mph in kilometres?

The "per hour" bit is the same, so the question is equivalent to 65 miles in kilometres.

65 miles = 104.6 km so 65mph = 104.6 kmph.

How many meters are you traveling per second at 80kph?

82 kilometres = 82,000 metres

1 hour = 3,600 seconds

82,000 / 3,600 = 22.78 metres per second

Is it correct that the average velocity is always equal to the mean value of initial and final velocities?

No, the average velocity is calculated as the total displacement divided by the total time taken to travel that distance. It is not simply the mean of the initial and final velocities.
