A 1 kg Mass Has a Kinetic Energy of 1 Joule When Its Speed Is...
The kinetic energy (KE) of an object is the energy it possesses due to its motion. It is calculated using the following formula:
KE = (1/2) * m * v²
Where:
- KE is the kinetic energy (measured in Joules)
- m is the mass of the object (measured in kilograms)
- v is the velocity of the object (measured in meters per second)
We know that the mass (m) is 1 kg and the kinetic energy (KE) is 1 Joule. We need to find the velocity (v). Let's plug these values into the formula and solve for 'v':
1 Joule = (1/2) * 1 kg * v²
Now, let's simplify and solve for 'v':
1 = (1/2) * v² 2 = v² v = √2 ≈ 1.414 meters per second
Therefore, a 1 kg mass has a kinetic energy of 1 Joule when its speed is approximately 1.414 meters per second.
