Homework Statement
A 2.4kg- mass attached to a spring oscillates with an amplitude of 7.0cm and a frequency of 5.0Hz .
What is its energy of motion?
Express your answer using two significant figures.
in J.
The energy of motion, also known as kinetic energy, is the energy an object possesses due to its motion. It is dependent on the mass and velocity of an object.
The energy of motion is calculated using the equation E = 1/2mv^2, where E is the energy in joules, m is the mass in kilograms, and v is the velocity in meters per second.
In this scenario, the mass is 2.4kg and the amplitude is 7.0cm. The mass is the amount of matter in an object, while the amplitude is the maximum displacement from equilibrium in a periodic motion.
The frequency, which is the number of cycles or oscillations per second, is directly proportional to the energy of motion. This means that as the frequency increases, the energy of motion also increases.
Yes, the energy of motion can be converted into other forms of energy, such as thermal energy or potential energy. This is known as the law of conservation of energy, which states that energy cannot be created or destroyed, but can only be converted from one form to another.
