Kinetic Energy Formula:
| From: | To: |
The kinetic energy (KE) formula calculates the energy an object possesses due to its motion. It is given by \( KE = \frac{1}{2} \times m \times v^2 \), where m is mass in kilograms and v is velocity in meters per second.
The calculator uses the kinetic energy equation:
Where:
Explanation: The kinetic energy is directly proportional to the mass and to the square of the velocity of the object.
Details: Kinetic energy calculation is fundamental in physics and engineering for understanding motion, collisions, energy conservation, and designing safety systems.
Tips: Enter mass in kilograms and velocity in meters per second. All values must be positive numbers.
Q1: What are the units of kinetic energy?
A: Kinetic energy is measured in Joules (J) in the SI system.
Q2: How does velocity affect kinetic energy?
A: Kinetic energy increases with the square of velocity, meaning doubling velocity quadruples the kinetic energy.
Q3: Can kinetic energy be negative?
A: No, kinetic energy is always a positive quantity or zero for stationary objects.
Q4: What is the relationship between work and kinetic energy?
A: The work-energy theorem states that the net work done on an object equals its change in kinetic energy.
Q5: How is kinetic energy used in real-world applications?
A: Kinetic energy calculations are used in vehicle safety design, sports science, renewable energy systems, and many engineering applications.
