Question 14 (1 point)
When an object is in motion, it possesses what type of energy?
a
potential energy
b
kinetic energy
c
chemical energy
d
thermal energy
b) kinetic energy
When an object is in motion, it possesses kinetic energy.
The correct answer is b) kinetic energy.
When an object is in motion, it possesses kinetic energy. Kinetic energy is the energy associated with the movement of an object. It depends on two factors: the mass of the object and its velocity. The formula for kinetic energy is:
Kinetic Energy = (1/2) * mass * velocity^2
To determine the type of energy an object possesses when it is in motion, you need to understand the different types of energies. The options given in the question are:
a) potential energy: This is the energy possessed by an object due to its position or condition. It can be gravitational potential energy, elastic potential energy, or other forms, but it is not directly related to an object in motion.
b) kinetic energy: This is the energy of an object due to its motion. As mentioned earlier, it depends on the mass of the object and its velocity. When an object is in motion, it possesses kinetic energy, so this is the correct answer.
c) chemical energy: This is the energy stored in the bonds of chemical substances. It is related to chemical reactions and transformations, not necessarily to an object's motion.
d) thermal energy: This is the energy associated with the random motion of particles within a substance. It is related to heat transfer and temperature, not specifically to an object's motion.
Therefore, the correct answer is b) kinetic energy.
