Since Gravitational potential energy, P= mgh
therefore p is directly proportional to the height.
Hence the curve will be straight line with slope mg

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
Draw a new gravitational potential energy vs. height graph to represent the gravitational potential energy if the ball had a mass of 2.00kg. The graph for a 1.00kg ball with an arbitrary initial velocity is provided again as a reference.Take g = 10.0 m/s2 as the acceleration due to gravity.
Do not assume a constant g for this problem. The gravitational potential energy of a 1 kg object on the earth's surface is -6.28e7 J. How much work is required to lift that object to a height of 5e6 m? GM = 4e14m^3/s^2. Radius of earth = 6.4e6 m.
Derive an expression for the energy needed to launch an object from the surface of Earth to a height h above the surface. Ignoring Earth's rotation, how much energy is needed to get the same object into orbit at height h? Express your answer in terms of some or all of the variables h, mass of the object m, mass of Earth mE, its radius RE, and gravitational constant G.

4. The equation mgy for gravitational potential energy is valid only for objects near the surface of a planet. Consider two very large objects of mass m1 and m2, such as stars or planets, whose centers are separated by the large distance r. These two large objects exert gravitational forces on each other.The gravitational potential energy is U = − Gm1m2 r where G = 6.67 × 10−11Nm2/kg2 is the gravitational constant.

To understand the relationship and differences between electric potential and electric potential energy. In this problem we will learn about the relationships between electric force F⃗ , electric field E⃗ , potential energy U, and electric potential V. To understand these concepts, we will first study a system with which you are already familiar: the uniform gravitational field.
