What is the measure of the kinetic energy of the atoms of an object?

Kinetic energy is the energy created by the motion of an object. In classical mechanics, kinetic energy is calculated using the equation:

KE = 1/2 * m * v^2

(where KE = kinetic energy, m = mass, v = velocity)

Potential energy is energy that an object has simply due to its position and configuration. This energy can be caused by where it is in a force field. The most common potential energy is gravitational potential energy. There is also electrical, magnetic, and elastic potential energy. In classical mechanics, gravitational potential energy created by the Earth is calculated using:

PE = mgh

(where PE = potential energy, m = mass, g = acceleration due to gravity, h = height of the object)

Is kinetic energy is the energy an object has to due to its motion?

kinetic energy-energy in motion object that change from being at rest

What happens to the kinetic energy of a machine when it stops?

When a machine stops, its kinetic energy is converted into other forms of energy such as thermal energy or sound energy due to friction and other factors. Essentially, the kinetic energy is dissipated and transformed into different forms as the machine comes to a halt.

Is an athlete running a kinetic energy?

To walk you need to expend mechanical energy in forcing your body forwards through forcing your leg muscles to react with the ground through your feet. Your muscles obtain the energy from chemical reactions within your body, and ultimately from the food you have digested.

Is iron kinetic energy?

Iron itself is not kinetic energy; it is a chemical element. Kinetic energy is the energy an object possesses due to its motion. Iron can have kinetic energy if it is in motion, such as when it is moving as a part of a system or in a chemical reaction.

How do you go from a position graph to a velocity graph?

you can't....it's merely impossible!

Assuming it is a graph of velocity vs time, it's not impossible, it's simple. Average velocity is total distance divided by total time. The total time is the difference between finish and start times, and the distance is the area under the graph between the graph and the time axis.

What is thirty five mph in knots?

Thirty-five miles per hour is approximately 30.4 knots.

What is an apparatus that converts electric energy into kinetic energy?

An electric motor is an apparatus that converts electric energy into kinetic energy by using magnetic fields induced by electric current to generate rotational motion.

What is the formula for elastic collisions?

if we assume m1 (mass) and v1 (velocity) for first mass , m2 and v2 for second mass ,we have : m1 v1i + m2 v2i = m1 v1f + m2 v2f and 1/2 m1 v1i2 + 1/2 m2 v2i2 = 1/2 m1 v1f2 +1/2 m2 v2f2 i : initial f : final

This is a simplified version: vf1= ((m1-m2)/(m1+m2))(v1i)+ (2m2/(mi+m2)vi2

Why is kinetic energy denoted T?

'T' usually denotes temperature. In thermal physics, temperature is a measure of the kinetic energy of particles as they move around inside the substance.

I can't think of any other explanation, as the letter 'T' is not really linked with kinetic energy in any other situation.

The runner ran 1500 meters in 5 minutes and 22 seconds what was his speed in minutes and seconds?

First lets know the formula of average speed:

average speed= distance/time taken

here the distance: 1500 m and

time taken: 4 minutes

(the metre unit always should be with second unit)

So lets convert 4 mins into sec: 4*60= 240sec

average speed: 1500/240 = 25/4 = 6.25m/s

How do you calculate the force exerted on an object in a well flowing at a given rate?

To calculate the force exerted on an object in a well flowing at a given rate, you can use the formula: Force = Pressure x Area. First, calculate the pressure at the depth of the object in the well using the fluid's density, gravity, and depth. Then, determine the cross-sectional area of the object to which the pressure is being applied. Multiply these values to find the force exerted on the object.

What happens to the average kinetic energy of the particles in a simple of matter as the temperature of the simple is increase?

The particles move faster, bumping into each other more, causing the average distance between particles to increase.

Is dance a kinetic energy?

the movement in dance is kinetic energy. Kinetic energy is =1/2(mass)(velocity)^2.

if this is a homework question,

it might also relate to impulses (see link).

Means of transport which changes chemical energy into kinetic energy?

Many engines do this conversion. For example, the engines commonly found in cars convert the chemical energy first to heat (by burning it), then convert part of this heat into movement (kinetic energy).

If a slugs speed is 6.5 inchesin 120 minutes what is it in miles per hour?

To convert 6.5 inches per 120 minutes to miles per hour, we need to convert both the distance and time units. There are 63,360 inches in a mile, so 6.5 inches is 0.000102 miles. And there are 60 minutes in an hour, so 120 minutes is 2 hours. Finally, divide the distance by the time to get the speed: 0.000102 miles / 2 hours = 0.000051 miles per hour.

How does the weight of a bowling ball effect how many pins it knocks down?

Because a heavier ball has both more mass (weight) and inertia (resistance to being deflected), it's more likely to drive through the pins and cause them all to fall.

As strange as it sounds, on a textbook strike, the bowling ball itself only touches four of the ten pins. But it imparts energy to those pins, causing them to ricochet in a predictable pattern that causes them to take out the other six pins.

The heavier the ball is, the more energy it transfers to those four pins, and the more likely they are to carry out their job. Of course, this assumes the ball isn't too heavy for the bowler to throw; since Force = mass x acceleration, a lighter ball thrown harder can hit the pins with as much (if not more) power than a heavy ball thrown slowly.

What is the acceleration of an object thrown 3.5 meters at 44 meters per second?

The acceleration of an object thrown vertically upwards can be calculated using the kinematic equation (v_f^2 = v_i^2 + 2a \cdot d), where (v_f) is the final velocity, (v_i) is the initial velocity, (a) is the acceleration, and (d) is the distance. Given that the object is thrown vertically upwards, the equation becomes (0 = (44 , \text{m/s})^2 + 2 \cdot a \cdot (-3.5 , \text{m})). Solving for (a), we find that the acceleration is approximately -104 m/s², which indicates that the object is accelerating downwards.

What happens to velocity if you double kinetic energy?

The square of 2 is 4. So, if the velocity doubles, the energy increases by a factor of 4.

If a conveyor is moving at 3 miles per hour how many feet per minute is it moving?

3 miles per hour is equivalent to 264 feet per minute. This conversion can be done using the fact that 1 mile is equal to 5280 feet and there are 60 minutes in an hour.
