Answer:
Kinetic energy is the energy an object has because of its motion. If we want to accelerate an object, then we must apply a force. Applying a force requires us to do work. After work has been done, energy has been transferred to the object, and the object will be moving with a new constant speed.
<h2>
Answer: B. Gravitational potential energy </h2>
Explanation:
<em>The gravitational potential energy is the energy that a body or object possesses, due to its position in a gravitational field.
</em>
That is why this energy depends on the relative height of an object with respect to some point of reference and associated with the gravitational force.
In the case of the <u>Earth</u>, in which <u>the gravitational field is considered constant</u>, the value of the gravitational potential energy
will be:
Where
is the mass of the object,
the acceleration due gravity and
the height of the object.
As we can see, the value of
is directly proportional to the height.
Based on data from world energy consumption, the estimated humanity’s current consumption of energy in one day is above 208 million joules per day.
<h3>What is energy consumption?</h3>
Energy is the ability to do work. Therefore, energy consumption refers to the amount of energy used to do work.
Humans need energy for various purposes such as;
- lighting
- heating
- operation of machines
- feeding, etc.
Due to rapid growth on population as well as technology, the human energy consumption is on the increase.
In 2020, the world primary energy consumption was 71,4 GJ per person for a world population of about 7.7 billion people.
Therefore, the estimated humanity’s current consumption of energy in one day is above 208 million joules per day.
