Kinetic energy is the energy an object possesses due to its motion. The kinetic energy of an object depends on both its mass and its speed. The formula for kinetic energy is:

KE = 0.5 * m * v^{2}

- KE = kinetic energy (in joules)
- m = mass of the object (in kilograms)
- v = velocity of the object (in meters per second)

From the formula, we can see that the kinetic energy of an object increases with its mass and with the square of its velocity. This means that an object with a larger mass or a higher velocity will have more kinetic energy.

1. Mass: The kinetic energy of an object is directly proportional to its mass. A heavier object will have more kinetic energy than a lighter object with the same velocity.

2. Velocity: The kinetic energy of an object is directly proportional to the square of its velocity. This means that doubling the velocity of an object will quadruple its kinetic energy.

The standard unit of kinetic energy is the joule (J). In some cases, the kilogram-meter squared per second squared (kg·m^{2}/s^{2}) is also used as a unit of kinetic energy.

Here are some key points to remember about kinetic energy:

- Kinetic energy is the energy of motion.
- The formula for kinetic energy is KE = 0.5 * m * v
^{2}. - Kinetic energy depends on both the mass and the velocity of an object.
- An object with a larger mass or a higher velocity will have more kinetic energy.
- The standard unit of kinetic energy is the joule (J).

Ecosystems: Interactions, Energy, and Dynamics

Students who demonstrate understanding can:

Construct and revise an explanation based on evidence for the cycling of matter and flow of energy in aerobic and anaerobic conditions.

Use mathematical representations to support claims for the cycling of matter and flow of energy among organisms in an ecosystem.

Evaluate the claims, evidence, and reasoning that the complex interactions in ecosystems maintain relatively consistent numbers and types of organisms in stable conditions, but changing conditions may result in a new ecosystem.
