#### Formula for Calculating Kinetic Energy The formula for calculating kinetic energy is: **Kinetic Energy (KE) = 1/2 * mass * velocity^2** Where: - KE is the kinetic energy of the object, - mass is the mass of the object, and - velocity is the velocity of the object. This formula states that the kinetic energy of an object is directly proportional to its mass and the square of its velocity. Please note that the formula assumes the object is moving in a straight line and does not take into account factors such as air resistance or other forces acting on the object. Let's use this formula to calculate the kinetic energy of an object. #### Example Calculation Let's say we have an object with a mass of 2 kilograms (kg) and a velocity of 5 meters per second (m/s). We can calculate the kinetic energy using the formula: KE = 1/2 * mass * velocity^2 Substituting the given values: KE = 1/2 * 2 kg * (5 m/s)^2 Simplifying the equation: KE = 1/2 * 2 kg * 25 m^2/s^2 KE = 25 kg m^2/s^2 Therefore, the kinetic energy of the object is 25 joules (J). #### Conclusion The formula for calculating kinetic energy is KE = 1/2 * mass * velocity^2. It is used to determine the amount of energy possessed by an object in motion. In the example provided, we calculated the kinetic energy of an object with a mass of 2 kg and a velocity of 5 m/s to be 25 J.
