What else can I help you with?
The potential energy of a pendulum is least?
At the highest point of its swing where its kinetic energy is least and potential energy is maximum.
If an object's mechanical energy is equal to its potential energy how much kinetic energy does it have?
Mechanical Energy= Potential energy+ Kinetic energy, so for the mechanical energy to be equal to be potential energy, the kinetic energy must be 0.
The type of energy a ball has when you hold it above the ground?
Potential energy is a stored energy due to the gravity and height above the ground. In physics the formula for potential energy is: PE = mgy where m = mass (kg), g = acceleration due to gravity (m/s^2), y = height (m) What if there is no height? Well, by simply letting y = 0 and multiplying 0 to m and g, we get PE = 0. Therefore potential energy does not exist and shows it is only present when the object has a height above the ground.
If a proton moved from 0 V potential to 5 V potential would its potential energy increase or decrease?
Electric field points from high potential to low potential. Positive particles had tendency to follow electric field. If you are moving the particle against this tendency you are doing work, and this work give more potential energy to the particle.
Why an object at rest on the ground has 0 Joules gravitational potential energy?
An object at rest on the ground has 0 Joules of gravitational potential energy because potential energy is calculated relative to a reference point, typically a certain height above the ground. When the object is on the ground, the height is considered to be zero, so there is no potential energy stored in the object relative to that reference point.

Does a man possess potential energy?
Potential energy can be calculated by the equation U ( which is the potential energy) = mgh, where m is hte mass, g is gravity, and h is the height of the object above the point where h=0 (often the ground). So, as long as h does not equal zero (imagine the man sandin on a cliff above sea leve, which is h=0) then he will have potential energy.
Where does the pendelum posses the highest potential energy?
At it's highest point where it begins to come back down. It has 0 kinetic energy, so that is when it has the most potential.
What is the two forms of energy?
Kinetic energy (energy of motion) and potential energy (stored energy) A ball at the top of a building getting ready to be dropped has potential energy, but a ball falling has kinetic energy If the ball is at the top of the building, it has 100% potential and 0% kinetic and when it is halfway from top to bottom and falling it has 50% of each
River water held behind a dam i sbest described as a form of kinetic energy chemical energy entropy thermodynamics or potential energy?
Potential energy. The water behind a dam has stored potential energy due to its position above the ground level. This potential energy can be converted into other forms of energy, such as kinetic energy, when the water is released and flows downstream.
Is chemical energy kinetic energy or potential energy?
Chemical energy is a form of potential energy stored in the bonds of chemicals. When these bonds are broken, the potential energy is converted into other forms of energy, such as kinetic energy.
How much potential energy does a ball have when it reaches the top of its ascent being 1kg with a velocity of 30msec?
The potential energy of an object at a particular height is given by the formula: Potential Energy = mass x gravity x height. At the top of its ascent, the ball's height is maximum, meaning all of its initial kinetic energy has been converted to potential energy. Therefore, the potential energy of the ball at the top of its ascent is 0.
How are potential and kinetic energy related?
Potential and kinetic energy are related in that potential energy is stored energy that can be converted into kinetic energy, which is the energy of motion. When an object has potential energy, it has the potential to move and therefore has the potential to have kinetic energy.
