The total mechanical energy of an object is the sum of its kinetic energy and potential energy.

## What is the sum of kinetic?

The total mechanical energy of an object is the sum of its kinetic energy and potential energy.

## What is the SI unit of potential energy?

joule

## How do you find kinetic energy with mass and height?

The kinetic energy equation is as follows: KE = 0.5 * m * vĀ², where: m – mass, v – velocity. KE = a million/2 mv^2 = mgh – Fd = PE – paintings in opposition to friction.

## What type of energy is nuclear?

Nuclear energy is a non-renewable energy source that comes from the nucleus of atoms. Nuclear fusion is when the nuclei of atoms are combined or fused together. Nuclear fission is when the nuclei of atoms are split apart. Nuclear power plants produce electricity by using nuclear fission.

## How does the kinetic energy of a moving body depends on its speed?

This equation reveals that the kinetic energy of an object is directly proportional to the square of its speed. That means that for a twofold increase in speed, the kinetic energy will increase by a factor of four. For a threefold increase in speed, the kinetic energy will increase by a factor of nine.

## How do you find speed with kinetic energy?

In classical mechanics, kinetic energy (KE) is equal to half of an object’s mass (1/2*m) multiplied by the velocity squared. For example, if a an object with a mass of 10 kg (m = 10 kg) is moving at a velocity of 5 meters per second (v = 5 m/s), the kinetic energy is equal to 125 Joules, or (1/2 * 10 kg) * 5 m/s2.

## What best compares potential and kinetic energy?

the statement with best compares potential energy and kinetic energy is that only kinetic energy increases when the velocity of the object increases. Explanation: the kinetic energy is dependent on the motion of the body. Then the velocity of the body increases the kinetic energy also increases exponentially.

## What is the difference between kinetic energy and potential energy Brainly?

Answer. Answer: The Kinetic energy of an object is the energy that it possesses due to its motion But Potential energy is the energy that is stored ā or conserved – in an object or substance.

## What is the difference between the kinetic energy and potential energy?

Energy stored in an object due to its position is Potential Energy. Energy that a moving object has due to its motion is Kinetic Energy.

## How many different forms of energy are there?

six basic

## Why is potential energy higher than kinetic energy?

An object can have both kinetic and potential energy at the same time. For example, an object which is falling, but has not yet reached the ground has kinetic energy because it is moving downwards, and potential energy because it is able to move downwards even further than it already has.

## What are two main types of energy?

After hundreds of years of observation and experimentation, science has classified energy into two main forms: kinetic energy and potential energy. In addition, potential energy takes several forms of its own.

## What is the kinetic energy of a 1200 kg object that is moving with a speed of 24 ms?

KINETIC ENERGY=345600Joules.

## What types of energy are potential and kinetic?

Potential energy is stored energy and the energy of position ā gravitational energy. There are several forms of potential energy. Kinetic energy is motion ā of waves, electrons, atoms, molecules, substances, and objects. Chemical Energy is energy stored in the bonds of atoms and molecules.
