1. What Is Kinetic Energy?

Kinetic energy is the energy possessed by an object due to its motion. It is a scalar quantity that depends on both the mass and velocity of the object.

2. How Does The Calculator Work?

The calculator uses the kinetic energy formula:

Where:

• \( KE \) — Kinetic Energy (Joules)
• \( m \) — Mass of the object (kilograms)
• \( v \) — Velocity of the object (meters per second)

Explanation: The kinetic energy increases with the square of the velocity, meaning that doubling the speed quadruples the kinetic energy.

3. Importance Of Kinetic Energy Calculation

Details: Calculating kinetic energy is essential in physics and engineering for understanding energy conservation, collision dynamics, and designing safety systems in vehicles and machinery.

4. Using The Calculator

Tips: Enter mass in kilograms and velocity in meters per second. All values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: What are the units of kinetic energy?
A: Kinetic energy is measured in Joules (J) in the International System of Units (SI).

Q2: Can kinetic energy be negative?
A: No, kinetic energy is always a positive quantity or zero (when velocity is zero).

Q3: How does mass affect kinetic energy?
A: Kinetic energy is directly proportional to mass - doubling the mass doubles the kinetic energy (at constant velocity).

Q4: What is the relationship between velocity and kinetic energy?
A: Kinetic energy is proportional to the square of velocity - doubling the velocity quadruples the kinetic energy.

Q5: Is kinetic energy conserved in collisions?
A: In perfectly elastic collisions, kinetic energy is conserved. In inelastic collisions, some kinetic energy is converted to other forms of energy.
