How the kinetic energy of an object changes when the speed of the object doubles?
Look at the formula for the kinetic energy of an object: KE = 1/2 M V2Did you notice that " V2 " ? That means the KE is proportional to the squareof the object's velocity.So if the object's speed doubles, its KE increases by (2)2 = a factor of 4.
KE of an object when you double the velocity?
Kinetic energy = 1/2 (Mass) (Velocity)2. Since KE is proportional to V2, doubling the velocity increases KE by 22 = a factor of 4.
When negative work is done on a moving object it's kenetic energy?
When negative work is done on the object, the object's energy decreases. This MAY be kinetic energy, but some other form of energy may increase instead, for example, potential energy or heat energy.
What is PE and KE?
PE in physics is Potential Energy which means: energy an object has because of the position, shape, or condition of the object. KE in physics is Kinetic Energy which means: the energy of an object that is due to the object's motion.
When does a object have the most kinetic energy?
In the case of a falling object, the instant before the object hits the ground. U = KE + PE; PE=-KE . Inversely, the object has the highest potential energy (lowest kinetic energy) at the starting point of the fall.
How does potential energy turn to kenetic?
Potential energy turns into kinetic energy when an object at rest begins to move. As velocity increases, KE increases and PE decreases.
When temperature increases the kinetic energy of the particles decreases?
Kinetic energy is directly related to temperature, because temperature is the average kinetic energy of an object. Therefore, as the temperature of an object decreases, its kinetic energy decreases, as well.
What can you infer in the relationship of PE and KE of free falling body?
As the energy is conserved, PE + KE = constant So as PE decreases KE increases by the same amount
What do you know about interconversion of energy of kinetic energy and potential energy of free falling bodies?
The potential energy decreases as the body falls while the kinetic energy increases. P.E.=mass x gravity x height The shorter the height the less potential energy there is K.E.= 1/2 x mass x velocity^2 The velocity increases as the body falls and the bigger the velocity the more Kinetic Energy produced

If a car increases its speed from 10.7 mph to 32.1 mph by what factor does the KE of the car increase?
yes as ke depends upon velocity and mass of an object
When negative work is done on a moving object it's kenetic energy?
When negative work is done on the object, the object's energy decreases. This MAY be kinetic energy, but some other form of energy may increase instead, for example, potential energy or heat energy.
How are potential energy and kinetic energy transferred on the first hill of a roller coaster?
At the top of the first hill, PE is at its maximum, whereas KE is zero. When the train starts to fall down the first hill, PE decreases and KE increases. At the bottom of the hill, KE is at its maximum, and PE is zero.
When kentic energy is passed from one object to another?
The first object loses KE and the second gains KE.
What happens when kinetic energy is absorbed as an object moves toward the earth?
The kinetic energy increases as the velocity increases (KE = 1/2mv2) until terminal velocity is reached, at which point the velocity becomes constant, and kinetic energy will no longer increase. The potential energy and kinetic energy will be at equilibrium, where PE = -KE.
How many times does the kinetic energy of a car increase when traveling 60 mph as opposed to traveling 15 mph?
60/15 = 4The KE of an object is proportional to the square of its speed.Multiplying the speed by 4 increases the KE by (4)2 = 16 .
