Characteristics of Kinetic Energy?

The good things about heat is that it keeps you warm and it can be bad at the sometime's it is good. Like it can cause global warning but heat can cook things , make things , and keep your body at a curtian temp but I'm just in grade 7 and i don't know how to answer this question but i hope i helped you . from angel .b z

Does work done has a unit?

Yes, work done has a unit. It is usually measured in joules (J) in the MKS (meter-kilogram-second) system or in foot-pounds (ft-lb) in the imperial system. Work done is defined as the product of force applied and the distance over which the force is applied.

The velocity of blood is slowest in the?

The velocity of blood is slowest in the capillaries. This allows for maximum exchange of nutrients, gases, and wastes between the blood and the surrounding tissues.

3 examples of an inclined plane?

Inclined planes are usually used for making work easier. They are used as loading ramps on trucks, as a away to help people in wheelchairs have the access they need, and they are used as slides, for fun.

How can kinetic energy be transferred into heat energy?

Hi everyone,

Energy, like a a question the same, can be transferred by Kinetic or potential energy, but the most common way is:

Energy is transferred by the movement of atoms,

Atoms that can insulate heat the best is the ones

that have atoms close together.

Atoms that are poor insulators have atoms that are

atoms far apart, or spaced out.

I hope this helps, everyone!

i've used this for my science fair project, and it got me 3rd place :D

How fast can a Dolphin swim in MPH?

Dolphins can swim at speeds of up to 20-25 miles per hour (32-40 kilometers per hour).

Can any object have mechanical energy even if its momentum is zero. Explain?

Yes - mechanical energy includes both gravitational potential energy, and kinetic energy. If an object's momentum is zero, then its kinetic energy will also be zero, but its potential energy can be positive or negative, depending on whether the object is above or below the chosen reference level.

What will happen to momentun if kinetic energy is tripled?

It depends on the mass of the object.K.E = 1/2mv2 =1/2mv*v = 1/2pv where p = momentum = mass * velocity.That is K.E = 1/2 pv.momentum depends on mass and velocity.Let in the first case K.E =1/2pv....(1) in the second case K.E = 1/2p1v but p1 = 3p. Then K.E = 1/2*3pv = 3*1/2pv = 3*K.E.

How quick is 200cc go kart in mph?

Im not sure either but i kno my dad took something off of mine and made it go atleast 40.

Does kinetic energy increase with increasing temperature?

It's more like temperature increases with increasing kinetic energy. In science, temperature is a measure of the average kinetic energy of a system. As a substance is heated it's particles move faster, increasing their kinetic energy, and this causes a rise in temperature.

How do you do the experiment of searle's apparatus young's modulus?

To conduct Searle's apparatus experiment for Young's modulus, a thin wire is suspended and a weight is hung from the bottom of it. The extension of the wire is measured and a graph is plotted to determine the Young's modulus. By varying the weight and measuring the extension, the relationship between stress and strain can be determined.

Where does the kinetic energy come from when a car accelerates uniformly starting from rest?

Chemical energy in the gasoline is released by burning a mixture of 'atomized'

gasoline and air. Most of the energy is used to heat the surrounding air, by means

of the engine's cooling system. The remaining small part of the energy is used

to turn the engine parts, which transfer the kinetic energy to the vehicle by way

of the transmission and the wheels.

When the vehicle needs to slow down or stop, the kinetic energy is instantly and

efficiently used to heat more of the surrounding air, by means of the braking system.

How is kinetic energy related to heat production?

Kinetic energy is directly related to heat production through the movement of molecules. When an object or substance gains kinetic energy, its molecules move faster, colliding with each other more frequently and with greater force, which generates heat. The heat produced is a form of energy resulting from the kinetic energy of the particles within the system.

B2 stealth fighter speed in miles per hour?

The B-2 Spirit's top speed is 1333 mile per hour. That is approximately Mach 1.7 or Mach 1.8.

If a object is moving at 400 miles per hour how many feet per second is this?

400 miles per hour is equivalent to 586.67 feet per second. To convert miles per hour to feet per second, you can use the conversion factor that 1 mile is equal to 5280 feet and 1 hour is equal to 3600 seconds.

Time65 miles per hour time65 and t65 all represent which of the following?

It appears that the terms you provided, "Time65," "miles per hour," "time65," "t65," all represent the concept of time measured in minutes or hours. The term "65 miles per hour" specifically represents speed, indicating a rate of 65 miles covered in one hour.

If a body with a mass of 88 kg is moving at a velocity of 13.89 meters per second what is it's kinetic energy?

The kinetic energy of the body would be 6671.904 J (joules). This can be calculated using the formula: KE = 0.5 * mass * velocity^2. Substituting the values given, you get KE = 0.5 * 88 kg * (13.89 m/s)^2 = 6671.904 J.

What will be the kinetic energy of an arrow having a potential energy of 50J after its shot from a bow?

Assuming no energy is lost, the 70 J of potential energy will be converted into 70 J of kinetic energy.

Assuming no energy is lost, the 70 J of potential energy will be converted into 70 J of kinetic energy.

Assuming no energy is lost, the 70 J of potential energy will be converted into 70 J of kinetic energy.

Assuming no energy is lost, the 70 J of potential energy will be converted into 70 J of kinetic energy.

When in a roller coaster ride does potential energy become kenetic energy?

Potential energy becomes kinetic energy when the car begins its downward descent from the top of one of the rollercoaster's peaks. It accumlates potential energy as it is lifted to the first and highest peak. It regains some of its lost potential energy each time it re-ascends one of the lower peaks, then loses potential and gains kinetic energy as it drops again.

How many mph is 6 ft per min?

To convert 6 feet per minute to miles per hour, you would first convert feet to miles. There are 5,280 feet in a mile. So 6 feet per minute is equal to (6/5280) miles per minute. Since there are 60 minutes in an hour, you would then multiply the result by 60 to get the speed in miles per hour.

Graphical representation of motion?

Position-Time Graph

You can graph motion on a position vs time graph. On a position vs time graph, position is on the y-axis and time is on the x-axis. If the velocity is constant, the graph will be a straight line and the slope is average velocity. If the motion is accelerating, the graph will be a curved line.

Velocity-Time Graph

You can also graph motion on a Velocity-Time graph. On a velocity vs time graph, velocity is on the y-axis, time is on the x-axis. If the graph is a straight line, velocity is constant and the slope is average acceleration. Also, on a velocity vs time graph, the area under the line is displacement.

Refer to the related link for illustrations of the different graphs of motion and their meanings.

How do you solve the time by the given of mass and kinetic energy?

Kinetic energy is equal to one-half of the product of an object's mass and the square of its velocity. Velocity is change in displacement divided by time. If you have the kinetic energy and mass, you can calculate the velocity by taking the square root of the quotient of kinetic energy and mass, and thereby solving for the velocity.

How is kinetic energy and momentum similar?

Answer #1:

Kinetic energy is the energy possessed by an object due to its movement

or motion. Momentum on the other hand, is the quantity of motion of an

object that is a product of its mass and velocity.

====================================

Answer #2:

Kinetic Energy = 1/2 M V2kg-m2/s2 (Newton-meter = Joule)

Momentum = M V kg-m/s (Newton-second)

Numerical Difference = (1/2 M V2) - (M V) = (M V) x (1/2V -1) .
