Yes. When an object speeds up, it has increasing kinetic energy and decreasing potential energy. When an object slows down, it has decreasing kinetic energy and increasing potential energy.

At greatest potential energy an object has no kinetic energy. An objects energy is preserved, so as an object drops it will lose the same amount of potential energy as it gains in kinetic energy.

yes it is, but you can only have kinetic energy of the object is in motion and potential energy if the object is any height above zero

No, Potential Energy is the energy of an object that has the potential to move while kinetic energy is the energy of an object at motion. Potential energy is defined by Mass * Gravity(9.81ms-2) * height(In meters) Kinetic energy is defined by (1/2)*Mass*Velocity2

Half of its maximum value. No matter where an object is in its trajectory, the kinetic energy and the potential energy of an object will always add up to be the same.

Yes, an object that is moving above earth's surface will have kinetic energy and potential energy.

no. if an object moves faster its kinetic energy increases but at the same time its potential energy decreases.

a body cannot have both kinetic and potential energy at the same time because, a moving body can only possess kinetic energy at a time, but potential energy is one possessed by a body with respect to its possition.

potential energy is typically measured as m*g*h which means that its a function of height. kinetic energy is .5*m*v^2 , which means kinetic energy is dependent on velocity. therefore if an object is at any altitude and has some velocity it has kinetic and potential energy

Yes, a falling object has only potential energy at its highest point at rest. The same object will also have all kinetic energy and no potential energy the instant just before striking the ground at its highest velocity at ground level.

Yes. A body can have potential energy and vector(kinetic) energy at the same time.

your question is to be answered accordingly. let me give you an eg.: a free falling object has potential energy max. but to its mid way both potential & kinetic energy are equal then slowly its kinetic energy increases & potential energy decreases. but if force & displacement are equal then both are same at certain height

No. You take energy out of your muscles and use it to add kinetic energy to the object when you throw it.As the object moves upward, it slows down. The kinetic energy is changing to gravitational potential energy.Finally, the kinetic energy is zero, the object starts moving downward, and its gravitational potential energystarts turning back into kinetic energy. It hits the ground with the same kinetic energy you put into it whenyou threw it.

Yes it can; if an object is at the top of a cliff at rest it has potential energy before falling to the bottom of the cliff where all energy is converted to kinetic, but when it is already moving, say after falling off a cliff halfway down, it has kinetic energy and potential energy ready to turn to kinetic at thee bottom of the cliff.

when any object changes its elevation from the ground the potential energy is transferred negatively or positively into kinetic energy such that the sum of potential energy and kinetic energy remains constant. For example, if a ball falls down from a height above ground. Its starting kinetic energy is zero while the potential energy is maximum. the closer it comes to ground, the less is the potential energy and the greater is the kinetic energy. The same happens in water falls.

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.

They're not the same thing, potential energy is energy at rest whereas kinetic energy is energy in motion.

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.

Potential Energy is at rest and Kinetic Energy is in motion, but it is still the same energy.kinetic energy arises due to the motion of particles while potential energy is due to the position of particles.

they are not the same. kinetic energy is energe that an object has due to its motion. potential energy is stored and held in the readiness. for example kinetic energy would be like a bowling ball knocking over bowling pins. unlike kinetic energy, which is the energy of motion, potential energy is stored and may be used later on like a car stopping at a red light.

Potential is stored energy and Kinetic is just simple movement like windmills are powerd with Kinetic energy. They are both energy.

Chemical energy (let's say stored in batteries) is a potential energy. Potential energy is the same as stored energy. Whereas kinetic energy is the energy of motion.

Kinetic energy is energy in motion. so, yes, boiling water is using kinetic energy. This contrasts potential energy which is the potential for something to release energy. For example, Potential is a round rock on the top of a hill, and kinetic is that same rock rolling down it.

Hold a rock in the air ... it has potential energy. Drop it ... the potential energy will be converted into kinetic energy. It hits the ground and stop ... the kinetic energy will be converted into thermal energy. Note that the total energy in each case is the same.
