Gravitational potential energy is energy an object possesses because of its position in a gravitational field. The most common use of gravitational potential energy is for an object near the surface of the Earth where the gravitational acceleration can be assumed to be constant at about 9.8 m/s2.
Answer:
It simply means that, the pencil is long enough to attain a length of six (6) centimeters when measured with a measuring tool such as a ruler, tape, etc.
Explanation:
A scientific method can be defined as a research method that typically involves the use of experimental and mathematical techniques which comprises of a series of steps such as systematic observation, measurement, and analysis to formulate, test and modify a hypothesis.
Measurements refers to a process which typically involves identifying and determining the dimensions of a physical object. The dimensions include important parameters such as width, height, length, area, volume, circumference etc.
Hence, a pencil whose length is measured as 6 centimeters has a physical dimension that covers a distance of six (6) centimeters in terms of size.
In conclusion, the pencil would cover a length of six (6) centimeters when measured vertically and a corresponding height of six (6) centimeters when measured horizontally.
Answer:
heat energy
Explanation:
Friction causes the molecules on rubbing surfaces to move faster, so they have more energy. This gives them a higher temperature, and they feel warmer.
We actually cant, really. Black Holes are really very powerful and don't just happen in some random place in the cosmos. We have got shots of Black holes that you cannot even see, but all the other big black holes that look like something straight of a sci-fi movie that look real, are really just photo- shopped. good question. Hope This Helped.
In an uniformly accelerated motion, the velocity of the object follows the law:
where
is the initial velocity, a the acceleration and t the time.
In our problem, the robot starts from rest, so the initial speed is zero:
. The robot is in free fall, so the acceleraion is the gravitational acceleration
. therefore, after a time
, the velocity is
