9 hours ago Kinetic energy is the energy an object possesses because of its motion. This energy is dependent on the velocity of the object squared. So, when the velocity doubles, consequently the kinetic energy quadruples. Moreover, this energy should be either a zero or a negative value. Learn the Kinetic energy formula here.

1. Know the formula for calculating kinetic energy. The formula for calculating kinetic energy (KE) is KE = 0.5 x mv. Here m stands for mass, the measure of how much matter is in an object, and v stands for the velocity of the object, or the rate at which the object changes its position. Your answer should always be stated in joules (J), which is the standard unit of measurement for kinetic energy. It is equivalent to 1 kg * m/s.
2. Determine the mass of an object. If you are solving a problem where the mass isn’t given, you will have to determine the mass yourself. This can be done by weighing the object on a balance and obtaining the mass in kilograms (kg). Tare the balance. Before you weigh your object, you must set it to zero. Zeroing out the scale is called taring. Place your object in the balance. Gently, place the object on the balance and record its mass in kilograms. If necessary, convert grams to kilograms. For the final calculation, the mass must be in kilograms.
3. Calculate the velocity of the object. Oftentimes, the problem will give you the velocity of the object. If this is not the case, you can determine the velocity by using the distance an object travels and how long it takes to cover that distance. The units for velocity are meters per second (m/s). Velocity is defined by the equation, displacement divided by time: V = d/t. Velocity is a vector quantity, meaning it has both a magnitude and a direction. Magnitude is the number value that quantifies the speed, while the direction is the direction in which the speed takes place during motion. For example, an object’s velocity can be 80 m/s or -80 m/s depending on the direction of travel. To calculate velocity, simply divide the distance the object traveled by the time it took to travel that distance.
4. Write the equation. The formula for calculating kinetic energy (KE) is KE = 0.5 x mv. Here m stands for mass, the measure of how much matter is in an object, and v stands for velocity of the object, or the rate at which the object changes its position. Your answer should always be stated in joules (J), which is the standard unit of measurement for kinetic energy. It is equivalent to 1 kg * m/s.

2 hours ago Kinetic Energy is the energy an object has owing to its motion. In classical mechanics, kinetic energy (KE) is equal to half of an object's mass (1/2*m) multiplied by the velocity squared. For example, if a an object with a mass of 10 kg (m = 10 kg) is moving at a velocity of 5 meters per second (v = 5 m/s), the kinetic energy is equal to 125
