Understanding the Relationship
* Kinetic Energy (KE): The energy an object possesses due to its motion.
* Mass (m): The amount of matter in an object.
* Velocity (v): The speed and direction of an object's motion.
The Formula
The relationship between kinetic energy, mass, and velocity is expressed by the following equation:
KE = (1/2) * m * v²
Solving for Velocity (v)
1. Rearrange the equation:
To isolate velocity, we need to get 'v' by itself. Divide both sides of the equation by (1/2) * m:
v² = (2 * KE) / m
2. Take the square root:
To get 'v', take the square root of both sides:
v = √((2 * KE) / m)
Example
Let's say an object has a mass (m) of 10 kg and a kinetic energy (KE) of 500 Joules. To find its velocity:
1. Plug in the values:
v = √((2 * 500 J) / 10 kg)
2. Calculate:
v = √(100 J/kg)
v = 10 m/s
Therefore, the velocity of the object is 10 meters per second.
