False.
We know that gravitational potential energy energy
U=-GMm/r
at r= , Then U=0
(maximum value), otherwise U is negative.
The gravitational potential energy of an object is always positive? True or false. Explain your answer.
If Ep is gravitational potential energy of an object at height h, write down which one of the following is true: (A) g is always positive (B) Ep is always positive if h increases (C) g is negative for a falling object (D) Ep is always defined as zero at the Earth’s surface (E) g is constant everywhere in the universe
An object has 50J of gravitational potential energy. Which of the following statements is true? The object must also have 50J of kinetic energy. Gravity can do 50J of work on the object The total energy of the object must also be 50J. o Gravity has already done 50J of work on the object.
The potential energy of a spring is equal to ks. always negative. always positive. positive or negative.
Answer True or False for all statements. True/False A concave mirror always forms a virtual image of a real object. True/False The image produced by a convex mirror is always closer to the mirror than it would be in a plane mirror for the same object distance. True/False A concave mirror always forms an enlarged real image of a real object. True/False A virtual image formed by a concave mirror is always enlarged. True/False When an object is placed between a concave mirror and its...
True or False. An object at 2.0 meters above ground has twice as much potential energy than at 0.50 meters above ground.

Question 28 1 pts What is the gravitational potential energy of a 1- kg block at rest on a table 1 m above the floor? 01 9.8 O 32 O 11.8) 00 Question 29 1 pts A particle is moved from point A to point B against a conservative force. Which statement is true about the work done? O cannot be recovered by moving it from B to A O does not depend on the path taken between A and...
Select all of the following statements that are true about potential energy and conservative forces. Potential energy is the energy associated with the configuration of a system. It is only possible to have potential energy if there are 2 or more objects in the system that interact with each other through internal, conservative forces. Absolute values of potential energy have no meaning: only changes in the potential energy are physically meaningful. There is only one kind of potential energy: gravitational...
