When does a falling object have the greatest energy?
A falling object has the greatest potential energy when it is highest, at the beginning of the fall. It has the greatest kinetic energy when it is at its lowest, at the end of the fall. Without taking friction or air resistance into account, the beginning potential energy is the same as the final kinetic energy. If friction is considered, the beginning potential energy is greater.
Jill is getting ready to push little Frank in his swing She pulls Frank back as high as she can and then releases the swing What is the initial transfer of energy that accelerates the swing when s?
Potential energy mostly transferring to kinetic energy (some of the energy will also dissipate as heat from friction - air friction, friction where the ends of the chain or rope is rubbing against whatever it is attached to, etc.) The potential energy comes from Jill raising Frank in the gravitational field of the earth.
Is friction and air resistance an energy?
friction and air resistance are respectively the amount of force applied involving the dissipation of ENERGY and the oppsition offered to an object when moving in air. so friction and air resistance are not a type of energy but opposing forces .
Would the air in an inflated balloon be potential energy?
i probably wouldn't say the air had potential energy just that an inflated balloon has potential energy.
What energy changers on the pendulum bob swings?
a swinging pendulum has its potential and kinetic energy changing.when the swing is at xtreme position it has ma potential energy and at mean position it has max kinetic energy
What happens to potential energy when jumping out a plane?
Elevational potential energy is converted to kinetic energy and heat in the air as air friction sets a terminal velocity. If a parachute is not used, some additional energy is lost with the associated screaming...

What is the total kinetis energy and pontentail energy in an object og group of object?
If there is no energy lost to friction or air resistance, then the total energy is the sum of the kinetic and potential energies.

How does friction affect the distance traveled by a toy car after rolling down a ramp?
at the top of the ramp the toy has a certain amount of potential energy. The amount of this energy depends on the height of the ramp and the weight of the toy. (The toy's weight is dependent on its mass and the force of gravity.) As the toy rolls down the ramp this potential energy is converted to two other types of energy: Kinetic energy and heat energy. The amount of heat energy depends on friction and air resistance. The lower the total resistance the more kinetic energy, and the more speed, the toy has at the bottom of the ramp.
Suppose a falling object loses 7J of potential energy. How much kinetic energy will it gain?
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.
What happens with the energy that is not transferred from one trophic level to the next?
Those energy that are not transferred to ATP loss as heat.

A ball falling through the air has what kind of energy?
-- It has both potential and kinetic energy. -- The farther it falls, the less potential energy it has. -- Its kinetic energy keeps increasing until it reaches its terminal velocity, then the KE becomes constant. -- There's also some heat energy involved, on account of the friction between the ball and the air. That energy transfers between the ball and the air in a way that's probably quite complex.
