Kinetic Energy to Velocity Calculator:
Enter the values of kinetic energy, KE(J) and mass, m(kg) to determine the value of velocity, V(m/s).
Kinetic Energy to Velocity Formula:
Kinetic energy (KE) is the energy that an object possesses due to its motion. The velocity (V) of an object is directly related to its kinetic energy, with the relationship between these two fundamental concepts being crucial in fields such as physics, engineering, and various applications involving motion dynamics.
The velocity of an object can be calculated if its kinetic energy and mass are known, utilizing the principles of conservation of energy. A higher kinetic energy at a given mass corresponds to a greater velocity.
Understanding this relationship is essential for problems involving collisions, where kinetic energy may be converted to other forms of energy, and in determining the efficiency of various mechanical systems where energy conservation is key.
The velocity, V(m/s) in metres per seconds is calculated by taking the square root of twice the kinetic energy, KE(J) in joules and then divided by the mass, m(kg) in kilograms.
Velocity, V(m/s) = √(2 * KE(J) / m(kg))
V(m/s) = velocity in metres per seconds, m/s.
KE(J) = kinetic energy in joules, J.
m(kg) = mass in kilograms, kg.
Kinetic Energy to Velocity Calculation:
1.Calculate the velocity of a 10 kg object with a kinetic energy of 500 Joules.
Given: KE(J) = 500J, m(kg) = 10kg.
Velocity, V(m/s) = √(2 * KE(J) / m(kg))
V(m/s) = √(2 * 500 / 10)
V(m/s) = √(1000/10)
V(m/s) = √100
V(m/s) = 10m/s.
2.Determine the kinetic energy required to achieve a velocity of 20 m/s for an object weighing 25 kg.Top of Form
Given: V(m/s) = 20m/s, m(kg) = 25kg.
Velocity, V(m/s) = √(2 * KE(J) / m(kg))
KE(J) = V2(m/s) * m(kg) / 2
KE(J) = 202 * 25 / 2
KE(J) = 400 * 25 * 0.5
KE(J) = 5000J.
