Kinetic energy of particles?
Kinetic energy of particles is the energy associated with their motion. It is given by the formula KE = 1/2 mv^2, where m is the mass of the particle and v is its velocity. The greater the mass or velocity of a particle, the greater its kinetic energy.
How did the last ball in the figure on the right gain energy?
The last ball gained energy due to potential energy being converted to kinetic energy as it descended the slope. The higher elevation of the starting point stored potential energy, which was then transformed into kinetic energy as the ball rolled down the slope.
What is the difference between kinetic energy and pontential energy?
Kinetic energy is the energy an object possesses by virtue of its motion, while potential energy is the energy stored within an object due to its position or state. Kinetic energy depends on the object's mass and velocity, whereas potential energy depends on factors like height, deformation, or chemical composition. Both forms of energy can be converted into each other and are essential in understanding the behavior of physical systems.
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.
When does a bouncy ball has least potential energy?
Right before it hits the ground and right after it bounces back up.Potential energy is "stored energy;" the the energy of a body or a system with respect to the position of the body or the arrangement of the particles of the system. If an object is moving very fact, it has kinetic energy, but if an object is in a position where it has the potential to move fast but isn't moving or moving very slowly, the object has a lot of potential energy. A bouncy ball has a parabolic pattern (Like an upside-down U) of movement as it bounces. At the top of the parabola- when the bouncy ball is highest in the air- it has the highest potential energy because it is not moving for that instant, but has the capacity to do so. as it moves downwards, it loses potential energy and gains kinetic energy. By the time it is about to hit the ground, it has the greatest kinetic energy because it gains momentum, and the least potential energy. As the ball bounces back up, it loses momentum, so it is losing kinetic energy and gaining potential energy. A bouncy ball has the least potential energy right before it hits the ground and right after it begins bouncing back up.There is also an exchange of kinetic and potential energy as the ball hits the ground. Elastic energy is the potential mechanical energy stored in the configuration of a material or physical system as work is performed to distort its volume or shape. So, the kinetic gravitational energy (because gravity is doing the work) changes to elastic potential energy (it is not moving in any way for an instant, but has the potential to move in the sense of being squished down), and as the energy is being used to distort the shape of the ball, elastic kinetic energy. As the ball has been distorted to its maximum extent, it has more potential energy, which is transferred to kinetic as the ball first changes back to its original shape, elastic kinetic energy, and then bounces back up, when it begins to lose its kinetic energy again.
Compare potential and kinetic energy?
The difference between potential and kinetic energy all comes down to a very simple property of the object. If an object is moving, then it has kinetic energy, or kinetic energy is the energy of movement. Potential energy is energy that is stored in an object and can be released under the right conditions.
What is kinetic energy how is it measured?
I don't know how it is measured but i do know that it is basically movement energy. So if you waved your arm in the air right now, you have 'created' kinetic energy. hope this helps!
What is potential energy changed to kinetic energy?
Potential energy is when something is about to release its energy. Think of at a rollercoaster when it reaches the top, right before it is about to fall. That is potential energy because it could fall which will release the energy. Kinetic energy is the energy that is being released at that moment. For instance, the rollercoaster falling, it is being pulled downwards which is the kinetic energy.
What kind of energy does a hammer have right before it hits a nail?
Kinetic and potential.
Kinetic energy of particles?
Kinetic energy of particles is the energy associated with their motion. It is given by the formula KE = 1/2 mv^2, where m is the mass of the particle and v is its velocity. The greater the mass or velocity of a particle, the greater its kinetic energy.
How does a pendulum work?
greetings.a pendulum has both kinetic and potential energy at one point.when the pendulum is at its highest point it has potential energy.it has kinetic energy when the ball of the pendulum is right in the middle.get it?
Does a falling objects thermal energy change to kinetic energy?
Yes, I believe so. As it gains upward momentum it is using thermal energy, and when it stops, and falls with gravity back to earth it is using kinetic energy. I think that's right.
What energy does a moving fan have?
well your basicly said it right in the question with the word "moving". moving means kinetic energy
How is the temperature of a substance related to attraction between molecules and its states?
Gases have the most kinetic energy and the least attraction exists between its molecules. Liquids have the middle amount of kinetic energy and middle attraction. Solids have the least kinetic energy and most attraction exists between its particles. The answer above isn't totally accurate, although it is mostly right. However, the attraction between molecules DOES NOT CHANGE WITH TEMPERATURE. What changes is how much energy the atoms/molecules have to overcome that attraction. The higher the temperature, the more energy the molecules have, and therefore the less the attractive force between will actually pull them together. As an example, consider a space rocket. The force of gravity on the rocket is constant. However, when the rocket is launched, the rocket's engines overcome the attractive force of gravity (by accelerating in the opposite direction) and therefore the rocket takes off. The attractive force doesn't change -- but the rocket's engines are more powerful than that attraction. In the same way, the increased temperature doesn't change the attraction, but it allows the molecules to overcome it. Other example. Image you are rolling down a hill on a bicycle. In the middle of the downhill, there is a rise. Because you have speed from going downhill, this slight uphill section doesn't stop you. However, the slight uphill is still there! It just doesn't stop you because you are already going fast. But it still affects you.
When did the arrow have kinetic energy?
The arrow acquires kinetic energy when it is released from the bow and begins to move through the air. At this point, the stored potential energy in the bow limbs is converted into kinetic energy as the arrow accelerates forward.
How did the last ball in the figure on the right gain energy?
The last ball gained energy due to potential energy being converted to kinetic energy as it descended the slope. The higher elevation of the starting point stored potential energy, which was then transformed into kinetic energy as the ball rolled down the slope.
When temperature increases the kinetic energy of the particles decreases?
Kinetic energy is directly related to temperature, because temperature is the average kinetic energy of an object. Therefore, as the temperature of an object decreases, its kinetic energy decreases, as well.
