In an explosion, energy is converted into kinetic energy, But what kind of energy is converted into KE?
Answer : Chemical potential energy
Ex: the blasting of bombs
the pieces of bombs gets kinetic energy due to the chemical
reaction inside bomb during explosion.
when an object explodes into more than one piece , the chemical potential energy is converted into kinetic energy, with this energy the pieces of this object flies

what energy changes are associated with lighting a candle? (mention what kind of kinetic energy or potential kinetic energy are involved)
What is the relation of Kinetic and potential energy to temperature and what kind of energy causes the gas phase to go up? Find the temperature for equilibrium.
Challenge Problem: Momentum and Kinetic Energy An explosion causes an object, initially at rest, to break into two pieces. One of these pieces has twice as much kinetic energy as the other. What is the ratio of their masses? Which one has the larger mass? Is it the one with the larger kinetic energy, or the one with the smaller kinetic energy?
What kind of energy is a type of potential energy? Chemical Heat Kinetic Electrical If the sidewalk and cart dent one another too much, they accelerate toward one another. True False Consider the earth spinning from west to east on its axis. It is slowing down in its rotation due to friction with the air. Using the right hand rule, in what direction is the frictional torque? S pole to N pole N pole to S pole Counterclockwise along the...
In golf when the club is swung the potential energy is converted into Kinetic energy. True False
Assume that the kinetic energy of a 1500kg car moving at 135km/h could be converted entirely into heat. What amount of water could be heated from 22?C to 55?C by the car's energy? Express your answer using two significant figures.

suriace. A. (15 Pts.) If the 1320 eV kinetic energy of the electrons is completely converted to the photon energy, what is the wavelength of the X-rays produced? (10 points for correct work shown, 2 points for units, 3 points for correct answer). B. (10 Pts.) If the electron current is 2.75x10-A, how many photons are produced per second? (5 points for correct work shown, 2 points for units, 3 points for correct answer).
We learned in class that the kinetic energy (KE) of an object with mass m moving at velocity v is KE =½ m v^2. Accordingly, the kinetic energy (KE) per unit mass (m) of a body moving at velocity v is KE/m=v^2 /2. What is the asteroid’s kinetic energy per unit mass (J/kg) for an impact at this velocity? State your answer in units of J/kg. velocity is 29.8 km/s
