How is kinetic and potential energy demonstrated through the Law of Conservation of Energy?

Potential energy always is converted to kinetic energy after an object at rest begins to move. Energy is never lost or gained, instead, it is converted back and forth.
Hope that helps!

A boulder falling through the air has what type of energy?
a boulder falling through the air still has some potential energy, but some of its potential energy has changed to kinetic energy...so it has both potential and kinetic!
Energy conservation during free-fall?
potential energy = mass*acceleration due to grav*height=kinetic energy at any point + total energy dispersed as you move through the air (air resistance)
Is a kite flying through the air kinetic energy?
If the feather is moving, it has kinetic energy. If there is room beneath the feather for it to fall, it has potential energy due to gravity.
A soccer player kicks a ball into the air and it lands far down the field Which energy conversion occurs as the ball falls from its highest point?
When a soccer player kicks a ball into the air, its kinetic energy is drained through air resistance and by the force of gravity. At its highest point, the ball has all of its vertical kinetic energy converted into potential energy. As the ball falls, this potential energy is converted back into kinetic energy. It should be noted that through the entire process of rising and falling the ball maintained horizontal kinetic energy being dissipated by resistance until it hit the ground and stopped.
How can the law of conservation of matter be demonstrated?
When ice melts, its mass doesn't change. It just goes through a phase change and becomes water. Again, when water evaporates, it goes through a phase change and becomes water vapor. The conservation of mass is hence proved.

What has kinetic and potential energy?
A roller coaster is a good example for a place to find both kinetic and potential energy. Before a drop, it has potential energy. At the end of a drop, it has kinetic energy. Half way through the drop, it has kinetic and potential energy at the same time.
A 2 g bullet hits and becomes embedded in a 5 kg wood block hanging from a 1.40 m long string causes the block to swing through an arc of 4.50 What was the speed of the bullet before hitting the block?
Apply conservation of energy. When the block is at one extreme, the kinetic energy is equivalent to 0, while potential energy is available. Assuming no loss of energy (through noise and heat), the potential energy should be equal to the kinetic energy of the bullet before collision. Apply conservation of energy.

What is the motion of a pendulum by applying the universal law of conservation of energy?
At the highest point, the energy is in form of potential energy. At the lowest point, the potential energy has been converted to kinetic energy. Then, when it goes up again, the kinetic energy transforms back into potential energy. As energy gets lost (e.g., through friction), the pendulum will move slower and slower, and not go up as high as it did at first.
Is a riders highest point on a swing a potential energy or kinetic energy?
At the highest point it's potential energy, which is then completely converted to kinetic energy as the swing travels through its lowest point at maximum speed. With an ideal swing (no friction) the sum of potential and kinetic energy stays constant (it is 'conserved'). In practice it dies away as the swing slows down, but Conservation of Energy is an important principle in science.
When a baseball player throws a baseball he transfers kinetic energy from his body to kinetic energy in the ball Where does the baseball player get his kinetic energy from?
The kinetic energy comes from potential energy, which he got from ATP energy, which is produced through food. Potential energy is converted to kinetic energy after the muscles contract and relax. Sources: School science
Where are potential and kinetic energy in a blizzard?
The kinetic energy would be the energy of a piece of snow hurtling through the air. The potential energy would be calculated based on how far the piece of snow has to go to reach the ground.
Did wind possesses both kinetic and potential energy?
Blowing wind has kinetic energy. This can be transformed into electrical energy using a turbine to transform the wind into rotational kinetic energy and a generator or alternator to convert the rotational kinetic energy to electrical energy. Water above a dam has potential energy from gravity and also from the weight of the water around it. Once it is moving or flowing down through the pipes it then has kinetic energy.
