How does the law of conservation of energy relate to potential and kinetic energy?

According to the law of conservation of energy, energy cannot be created or destroyed, although it can be changed from one form to another. KE + PE = constant. As the car coasts down the hill, it moves faster and so it’s kinetic energy increases and it’s potential energy decreases.

What are some observations we can make to determine if something has energy your answer?

We can measure energy, just as we can measure the mass of an object or how fast a car is going. The mass of an object is given in grams or kilograms, the speed of a car is given in kilometers per hour (km/h). In the same way, energy is measured in joules. There are 1000 joules in a kilojoule.

What happens to kinetic energy when you double the velocity?

Kinetic energy is the energy of mass in motion. When we double the mass, we double the energy; however, when we double the velocity, energy increases by a factor of four.

Which law is based on law of conservation of energy?

the first law of thermodynamics
Energy is not created or destroyed but merely changes forms, going from potential to kinetic to thermal energy. This version of the conservation-of-energy principle, expressed in its most general form, is the first law of thermodynamics.

What happens to potential energy as kinetic energy increases?

In all physical processes taking place in closed systems, the amount of change in kinetic energy is equal to the amount of change in potential energy. If the kinetic energy increases, the potential energy decreases, and vice-versa.

How does potential energy increase?

Since the gravitational potential energy of an object is directly proportional to its height above the zero position, a doubling of the height will result in a doubling of the gravitational potential energy. A tripling of the height will result in a tripling of the gravitational potential energy.

What happens to potential energy as kinetic energy increases or decreases?
