What has greater kinetic energy a car traveling at 35 miles per hour or a car traveling at 50 miles per hour?
Kinetic Energy is defined as the energy associated with motion. This is in contrast to potential energy which is associated with an entity's energy at rest, and it's potential for motion. Kinetic Energy can be calculated using this formula: KE = 0.5*Mass*Velocity^2, where KE = Kinetic Energy It is apparent by the formula that the same car traveling at a higher speed will have a greater kinetic energy than it does when traveling at a lower speed. Therefore, when the car travels at 50 mi/hr it has a higher kinetic energy than when it travels at 35 mi/hr. Let me just note that if we were talking about two different cars then we'd have to consider the weights of the cars.
What is the conserved sum of the potential and kinetic energy?
Total energy.
If the same model plane travel 3 times faster than the same model airplane what is the kinetic energy of the faster plane?
The kinetic energy of an object varies as the square of its velocity (Kinetic energy = mv2/2). So a plane with the same mass travelling at 3 times the velocity will have 9 times the kinetic energy.
What form of energy does the wind possess?
KINETIC
Are gravitational potential energy and kinetic energy equal in all cases?
They're hardly ever equal. One of the few situations where they're equal is when you drop a weight to the ground from some height. Then, the gravitational potential energy and kinetic energy are equal when it's exactly in the middle of the drop, and the kinetic energy it has when it hits the ground is the same as the gravitational potential energy it had when you let it go.
