Question

hola mates :)
Bring out the formula for calculating kinetic energy.

thank you mates !!!!

Answer 1

hii mate

Know the formula for calculating kinetic energy.The formula for calculating kinetic energy (KE) is KE = 0.5 x mv2. 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.[5]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 * m2/s2.

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.[6]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.

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.[7] 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.

Write the equation. The formula for calculating kinetic energy (KE) is KE = 0.5 x mv2. 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.[8]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 * m2/s2.

Plug the mass and velocity into the equation. If you don't know the mass or velocity of the object, then you'll have to calculate it. But let's say that you do know both quantities and are working to solve the following problem: Determine the kinetic energy of a 55 kg woman running with a velocity of 3.87m/s. Since you know the mass and velocity of the woman, you can plug it into the equation:[9]KE = 0.5 x mv2KE = 0.5 x 55 x (3.87)2


Solve the equation. Once you've plugged in the mass and velocity, you can solve for kinetic energy (KE). Square the velocity and then multiply all of the variables together. Remember to state your answer in joules (J). [10]KE = 0.5 x 55 x (3.87)2KE = 0.5 x 55 x 14.97KE = 411.675 J

hope it helps...
