Kinetic Energy

Kinetic energy is the energy an object possesses due to its motion. The kinetic energy of an object depends on its mass and its velocity. The formula to calculate kinetic energy (KE) is:

center;">KE = 0.5 * m * v²

Where:
KE = Kinetic Energy
m = Mass of the object
v = Velocity of the object

Key Concepts

• Mass: The amount of matter in an object. It is usually measured in kilograms (kg).
• Velocity: The speed of an object in a particular direction. It is usually measured in meters per second (m/s).
• Kinetic Energy: The energy of motion possessed by an object. It is usually measured in joules (J).

Factors Affecting Kinetic Energy

1. Mass: The kinetic energy of an object increases with its mass. A heavier object possesses more kinetic energy at the same velocity compared to a lighter object.

2. Velocity: The kinetic energy of an object increases with the square of its velocity. This means that doubling the velocity will quadruple the kinetic energy of the object.

Examples of Kinetic Energy

Kinetic energy can be observed in various everyday scenarios, such as:

• A moving car
• A swinging pendulum
• A thrown baseball
• A person running
