Elastic potential energy is gained the more it is stretched (like a catapault or rubber band)
Gravitational potential energy is increased if the object is raised higher up (further away from the centre of gravity)
An object can possess energy by virtue of its motion or position. Kinetic energy depends on the mass of the object and its velocity. Potential energy depends on the position of the object relative to the body with which it interacts.
When work is done on an object, the object gains energy
when it does work, it will gain energy
You gain Potential Energy as you cycle up a hill.
39.2 joules of potential energy.
Your gravitational potential energy would increase in this case. Of course, this comes at the cost of another type of energy; in this case, chemical energy stored in your body, from the food you ate.
By using chemicals in a rocket engine to raise a vehicle high above the earth's surface, the vehicle will gain gravitational potential energy. It will also gain kinetic energy, depending on what trajectory it follows
Sure, you can add energy to an object. For example, you can heat an object up (to have it gain heat energy), you can raise it (to have it gain gravitational potential energy), or you can make it move (to have it gain kinetic energy). In each case, the energy has to come from somewhere.
potential energy
The coaster have a large amount of potential energy when it gain height, kinetic energy when it gain speed instead.
You gain Potential Energy as you cycle up a hill.
39.2 joules of potential energy.
If Gravitational potential energy = weight X height, then the book should gain 4joules
Your gravitational potential energy would increase in this case. Of course, this comes at the cost of another type of energy; in this case, chemical energy stored in your body, from the food you ate.
From what I understand: PE - Potential Energy (mgh) KE - Kinetic Energy (1/2 mv2) If one dismisses the friction with air (conservation of energy), a loss of 7 joules for potential energy means a gain of 7 Joules in kinetic energy.

There is more than one kind of potential energy. A rocket, when fueled, has chemical potential energy. When it burns its fuel, it loses chemical potential energy but gains gravitational potential energy. If it then falls back to the ground it loses gravitational potential energy but gains in heat and kinetic energy, until it burns up or crashes.
