Is it possible for a system to have negative potential energy? …
Yes
, Since the choice of the zero of potential energy is arbitrary.
What does it mean for a system to have negative potential energy?
# A negative potential energy means
that work must be done against the electric field in moving the charges apart
! # Assuming potential at infinity to be zero if electrostatic potential energy of the system is negative then net positive work by an external agent was required to assemble the system of charges.
Is it possible for a system to have negative potential energy quizlet?
Is it possible for a system to have negative potential energy?

What will happen if the potential energy is negative?
This process defines the electric potential of a point-like charge. … Therefore, a system consisting of a negative and a positive point-like charge has a negative potential energy. A negative potential energy means
that work must be done against the electric field in moving the charges apart!
What is the meaning of negative value?
In mathematics, a negative number
represents an opposite
. In the real number system, a negative number is a number that is less than zero. Negative numbers are often used to represent the magnitude of a loss or deficiency. … For example, −(−3) = 3 because the opposite of an opposite is the original value.
Why is work negative potential energy?
Gravity is doing work on the object by pulling it towards the Earth, but since you are pushing it in the other direction, the work you do on the box (and therefore the force) is negative. The field does negative work
when you increase a particle's potential energy
.
Which statement is true if air resistance can be ignored?
Which statement is true if air resistance can be ignored?
Both hit the ground at the same time. The one thrown at an angle hits the ground with a lower speed.
Can work be done on a system if there is no motion group of answer choices?
Can work be done on a system if there is no motion?
No
, because of the way work is defined.
How much gravitational potential energy did the ball lose?
How muchgravitational potential energy did the ball lose? A ball drops some distance and loses
30 J
of gravitational potential energy.
At what position does the ball have the most potential energy?
What do you think happens to the energy of a ball in a pendulum that swings back and forth? The ball
at the top of the swing
is briefly motionless. It has the greatest potential energy, because it is highest above the surface.
What will happen to the potential and kinetic energy as the ball falls?
As the ball falls towards the ground,
its gravitational potential energy is transformed into kinetic energy
. The kinetic energy of an object is the energy it possesses due to its motion. The kinetic energy of the ball will continue increasing as the ball gains momentum, until it finally collides with a surface.
Can kinetic energy of a body be negative?
Kinetic energy can't be negative
, although the change in kinetic energy Δ K Delta K ΔK can be negative. Because mass can't be negative and the square of speed gives a non-negative number, kinetic energy can't be negative.
Can work done be negative?
Negative work done – The work done is said to be
negative when force and displacement are in opposite directions
. Hence, work is negative. Note: Work done by friction is always zero because friction force and displacement act in opposite directions.
Why potential energy is negative when force is attractive?
well, the answer to this is simple. this is because at infinity we assume the p.e of any body to be 0, as force is 0.
At distances lesser than infinity
(i.e, in vicinity of attraction) the p.e will be lesser( energy decreases with decrease in distance) , which will obviously be negative.
