What else can I help you with?
When you throw a ball into the air its kinetic energy equals?
is converted to potential energy as it goes higher.
If you toss a ball in the air at what point does it have the most kinetic energy?
As soon as the ball has been released.In this case, the energy starts off purely kinetic; dependent on motion. Once the ball has reached it's highest point, it has converted to potential energy; dependent on height. It then resumes falling back to kinetic energy. This is best shown by a graph of energy over time where Potential energy is a parabola opened down (frown face) and Kinetic energy is a parabola opened up (smiley face).With this you can also note that Kinetic Energy + Potential Energy = mechanical energy. These two graphs added together should make a straight line for Mechanical energy (in simplistic demonstration).
How is kinetic energy defined?
Kinetic energy is the energy an object possesses due to its motion. It is calculated as one-half of an object's mass multiplied by its velocity squared (KE = 0.5 * m * v^2). The faster an object is moving or the more massive it is, the greater its kinetic energy.
What is cell potential in an electrochemical cell?
A galvanic cell is set up by generating a redox reaction, whose current is used to do work and the chemical energy is changed to electrical energy. Remember that a full oxidation-reduction reaction can be broken down to two half-reactions, one oxidation (loss of electrons) and one reduction (gain of electrons). There is a transfer of electrons from the anode (oxidation) to the cathode (reduction). There is a driving force that pulls the electrons from the anode to the cathode. This force is the cell potential of the electrochemical cell. It is measured in volts, which is 1 joule of work per Coulomb of charge transferred. Cell potential can be measured through a voltmeter. A voltmeter draws current through a known resistance. Notice, that a voltmeter is not precise because frictional heating occurs in the wire and uses some of the energy of the cell, so the number we get is actually less than the actual cell potential. It would be ideal to find the cell potential under zero current using a potentiometer. In these conditions, the cell potential has the same magnitude but opposite sign to the voltage of the potentiometer.
What is the level at which an organism gets its energy?
An organism gets its energy at the cellular level through processes such as cellular respiration or photosynthesis. These processes involve converting energy stored in organic compounds into a form that the organism can use for various metabolic activities.
What type of energy conversion occurs when a skater rolls down a half-pipe?
As a skater rolls down a half-pipe, gravitational potential energy is converted into kinetic energy. At the top of the half-pipe, the skater has maximum potential energy due to their height. As they descend, this potential energy decreases while their kinetic energy increases, allowing them to gain speed. This conversion continues as they move through the half-pipe, illustrating the interplay between potential and kinetic energy.
Where on a roller coaster is there equal amounts of potential energy and kinetic energy?
There would be equal amounts of kinetic and potential energy at the middle of a drop, because the potential energy would have lost half of it's amount and the kinetic energy would have gained that amount but none else so far. Pretty sure thats all right, 🖒
What will happen to the potential energy if the height is reduced into half?
If the height is reduced by half, the potential energy will also be reduced by half. This is because potential energy is directly proportional to the height of an object above a reference point, following the equation PE = mgh, where m is mass, g is acceleration due to gravity, and h is height.
What has kinetic and potential energy?
A roller coaster is a good example for a place to find both kinetic and potential energy. Before a drop, it has potential energy. At the end of a drop, it has kinetic energy. Half way through the drop, it has kinetic and potential energy at the same time.
When the K E of a pendulum is at half its maximum value how much P E does it posses?
When the kinetic energy of a pendulum is at half its maximum value, the potential energy it possesses will also be at half its maximum value. This is because the total mechanical energy of the pendulum (the sum of kinetic and potential energy) remains constant throughout its motion.
As the mass increases what happens to the potential energy?
It lowers proportionally to the decrease in the mass. Since potential energy = mgh, changing the "m" would completely change the potential energy. For instance if we look at g as 10 m/s^2 and h as 10m: The original mass is 10kg. (10kg)*(10m/s^2)*(10m)= 1000J If we cut the mass in half. (5kg)*(10m/s^2)*(10m)= 500J The potential energy is cut in half.
What pair of half- reactions would have a negative total reduction potential?
silver reduced , gold oxidized
A flowerpot falls from a ledge 50 m above the ground. compare the potential and kinetic energy when it is at 25 m above the ground to its original potential and kinetic energy?
After falling 25 meters, it has less potential energy, by an amount calculated with the formula mgh (mass x gravity x height). If you ignore air resistance, the kinetic energy will increase by the same amount.
How would you determine half wave potential accurately?
The half-wave potential can be determined accurately by performing cyclic voltammetry, where the potential is scanned back and forth to measure the current response. The half-wave potential is the potential at which the current reaches half of its peak value. This can be identified by analyzing the voltammogram data.
What is potenitial energy?
Potential energy is the opposite of Kinetic energy. Kinetic energy is energy being exerted while potential energy is energy that's stored up and can be 'potentially' used. The total amount of potential energy and kinetic energy must always stay the same. An example is when you drop a ball. Before you drop it all the energy is potential because the ball is not moving. When the ball is halfway down, half the total energy is potential and half is kinetic. When the ball reaches the ground, all the energy has turned into kinetic. Physics generally defines potential energy due to gravity as mgh, where m = mass, g = gravity (9.81 m/s) and h = height above the ground. There's also elastic potential energy which is 1/2kx^2 where k = a spring constant and x = distance away from equilibrium.
Where the kinetic energy and potential energy becomes equal in simple pendulum?
A pendulum oscillates between two stationary points at the ends of its swing, with maximum speed at the center of the swing. So the kinetic energy is highest at the swing center where it is travelling fastest, and drops to zero at the stationary end points. The potential energy does the opposite, being a maximum at the ends and minimum in the center.
Can an object have kinetic and potential energy?
Absolutely. Kinetic energy, in other words, means that the object in question is moving. Potential energy is measured in distance from the ground. The higher the object, the more potential energy it has. An object can be moving and can be off the ground, so, technically, yes.
