Gravity is an attractive force that exists between any two objects in the universe. The force of attraction between two objects depends on the masses of the objects involved and on the distance between the objects. Newton's Law of Universal Gravitation quantifies this attractive force in an equation: F = G•m 1 •m 2 /d 2 As a general rule, potential energy depends on where you are; kinetic energy depends on how you move. So whether or not an object is sitting at rest or moving makes no difference insofar as its potential energy is concerned. Now Newtonian physics. B. negative and depends on the path taken. C. positive and independent of the path taken. D. negative and independent of the path taken. Gravity is a vertical force, and therefore only the vertical component of the displacement is important here. It is positive because the hiker moves in the direction of the force (gravity is acting downward) ** Energy is the most fundamental concept in physics**. Whatever be the operating force (electromagnetic, gravitational, strong or weak), every change that occurs in the universe is a conversion from potential to kinetic energy.From merely being in a position in space, in presence of forces, a particle has an inherent energy associated with it, that's termed as potential energy

This activity shows students the engineering importance of understanding the laws of mechanical energy. More specifically, it demonstrates how potential energy can be converted to kinetic energy and back again.

To demonstrate, let's calculate the potential energy of the same 1360 kg automobile if it were parked on the top level of a parking garage 36.6 m (120 ft) high. Its potential energy is equivalent to the amount of work required to raise the vehicle from street level to the top level of the parking garage, which is w = Fd * 13*.6: Gravitational Potential Energy The gravitational potential energy of the two-particle system is: U(r) approaches zero as r approaches infinity and that for any finite value of r, the value of U(r) is negative. If the system contains more than two particles, consider each pair of particles in turn, calculate the gravitational potential.

PE = Mb x g x H. (Potential Energy equals Mass of object times g times Height above ground) In this case the ball weighs 0.5 kilograms (kg). Clayton is holding it 2 meters (m) above the ground. The acceleration caused by the force of gravity on earth is always 9.8 meters per second squared (m/s^2) Potential energy is energy stored within a body due to its position. For example, a bowling ball held up in the hand of a person contains stored energy. Gravity tends to bring the ball back to ground surface. If the bowling ball is dropped, it will fall down to the ground and the potential energy in the ball will be converted to kinetic energy Kinetic energy refers to the energy present in the object due to the motion of a body. Potential energy refers to the energy present in an object due to its position. 4. K.E = (1/2)mv 2 where m is mass and v is speed. P.E = mgh where m is mass, g is gravity and h is height Gravitational potential energy depends on how high of the ground you are, e.g. if you hold a book above your head, that book has more potential energy than a book that is sitting on the ground. The potential energy of the bungee cord depends on how much the cord has been stretched, i.e. the bungee cord has more potential energy when it is. PE is potential energy, m is mass, g is acceleration due to gravity, and h is height. A common unit of potential energy is the joule (J). Because potential energy reflects the position of an object, it can have a negative sign. Whether it is positive or negative depends on whether work is done by the system or on the system
