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) .

Can kinetic energy be measured?

Kinetic energy can be measured, but the act of measuring it changes the kinetic energy of the object you are measuring. For example, you can measure the kinetic energy of a bullet fired from a gun by allowing the bullet to strike an known object and then measure the deflection/deformation of the target object. While it is possible to measure the kinetic energy of the bullet this way, the bullet itself is no longer moving after this measurement, and therefore your measurement caused a change in the bullet's kinetic energy.

.

Kinetic energy (E) can be calculated without changing the kinetic energy of the object under observation if you know the mass (m) of the object and if you can observe or calculate its velocity (v) using the equation E=(1/2)m/v2.

Is it possible to differentiate acceleration with respect to time if so what is the derivation?

Certainly. If acceleration isn't a constant, then it can be differentiated with respect to

time, and what you have is simply the third derivative of position. We're not aware of

any particular name that's been attached to that quantity.

One reference is that change in acceleration is called surge.

How fast are rough collies in mph?

Rough Collies can typically reach speeds of 20-30 mph when running at their fastest.

Why does a bullet go so fast?

gunpowder burns creating great heat , air pressure increases proportionally , and, like an air rifle, immense pressure creates force on back of slug accelerating it along the tightly fitting gun barrel. Imagine say 20g slug accelerated (assume uniformly) to 2000m/s in 10cm of gun barrel and calculate average force required to do it , this being testimony to gunpowder's tremendous potential energy.

What is the Emergency Highway Energy Conservation Act?

The Emergency Highway Energy Conservation Act was a law enacted in the United States in 1974 in response to the oil crisis. It aimed to conserve fuel by establishing a national speed limit of 55 mph on highways and promoting fuel-efficient driving practices. The act was repealed in 1995.

What is energy and how is it different from kinetic energy?

Energy is the capacity to do work or produce heat. Kinetic energy is a type of energy associated with the motion of an object. While energy is a broad concept that encompasses various forms like kinetic, potential, and thermal energy, kinetic energy specifically refers to the energy of motion.

When an object is lifted 12 feet off the ground it gains a certain amount of potential energy if the same object is lifted 36 feet off the ground its potential energy is?

The potential energy of an object can be calculated using the simple formula

Potential Energy = mass*acceleration due to gravity*distance above ground.

For simplification, we can call the mass m and the acceleration g. Using these values, the object will have a potential energy of 12m*g when it is 12 feet off the ground. When it is 24 feet off the ground, it will have an energy of 24*m*g. This is nothing more than twice the value we calculated before, so we can say that the object's potential energy at 24 feet is twice its potential energy at 12 feet. In order to give an exact value, we would need to know the mass of the object as well.

A man hoists himself up in a basket The combined mass of the man and basket is 95 kg With what force magnitude must the man pull on the rope if he is to rise with a constant velocity?

The man must pull with a force equal to his weight plus the weight of the basket, which is 95 kg * 9.8 m/s^2 ≈ 931 N. Since he is rising with constant velocity, this force must also counteract the force of gravity pulling him down.
