Answer:
Potential energy is energy that is stored in a person or object.Gravitational potential energy depends on an object's weight and its height above the ground (GPE = weight x height). Elastic potential energy is due to an object's shape. It results when an elastic object is stretched or compressed.
Explanation:
Answer:
We need, mass, gravity and height.
Explanation:
When a body falls freely from a height, its initial velocity is zero, but due to the height it has some potential energy at the top and the kinetic energy is zero.
As it falls, the potential energy is gradually converted in to the kinetic energy so that the total energy of the falling body is conserved.
At the time as the body strikes the ground, the entire potential energy is converted into the kinetic energy.
Potential energy is given by
U = m g h
where, m is the mass, g is the gravity and h is the height,
So, to get the kinetic energy we require mass, gravity and height of the body.
Explanation:
bacteria...Bacteria are considered to be prokaryotes, which means they do not have a nucleus and other membrane-bound organelles.
I'm pretty sure the answer to this question is B. If the behavior is common in certain cultures
Their behavior wouldn't be wrong or considered a psychological problem if it's part of their culture.

Answer:
<h2>
300 Joules</h2>
Explanation:
This is a common question on Khan Academy's "Calculating change in kinetic energy from a force" practice exercises. (AP Physics 1)
- The simplest method to use is the following:
, where W represents work (joules), F represents force (newtons), d represents distance (meters), and theta represents the angle of the force that's being applied. - In this scenario, the force being applied is horizontal, so we can remove the
from our equation. - So, our equation is now:
. This would mean that 
, which is equal to 
. - Our answer is 300 joules. (this value is positive and not negative because kinetic energy is being GAINED, not LOST)
Here's the real question without all the formatting:
- A truck pushes a pile of dirt horizontally on a frictionless road with a net force of 20 N for 15.0 m. How much kinetic energy does the dirt gain?
