Initial Kinetic Energy Formula:
| From: | To: |
The initial kinetic energy formula calculates the energy possessed by an object due to its motion. It is given by \( KE_{initial} = \frac{1}{2} \times m \times v_{initial}^2 \), where m is mass and v_initial is initial velocity.
The calculator uses the initial kinetic energy formula:
Where:
Explanation: The formula shows that kinetic energy is proportional to the mass of the object and the square of its velocity.
Details: Calculating kinetic energy is essential in physics and engineering for understanding energy conservation, collision dynamics, and motion analysis.
Tips: Enter mass in kilograms and initial velocity in meters per second. Both values must be valid (mass > 0, velocity ≥ 0).
Q1: What units should I use for mass and velocity?
A: Use kilograms (kg) for mass and meters per second (m/s) for velocity to get results in joules (J).
Q2: Can kinetic energy be negative?
A: No, kinetic energy is always non-negative since mass is positive and velocity is squared.
Q3: How does velocity affect kinetic energy?
A: Kinetic energy increases with the square of velocity, meaning doubling velocity quadruples kinetic energy.
Q4: What is the difference between kinetic and potential energy?
A: Kinetic energy is energy of motion, while potential energy is stored energy due to position or configuration.
Q5: Is this formula applicable to all objects?
A: This formula applies to objects moving at non-relativistic speeds. For objects approaching light speed, relativistic corrections are needed.
