Kinetic Energy – This is the energy of the light due to its motion. Note that because a photon has no mass, its kinetic energy equals its total energy.

The Momentum Calculator uses the formula p=mv, or momentum (p) is equal to mass (m) times velocity (v). The calculator can use any two of the values to calculate the third.

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 Joules, or (1/2 * 10 kg) * 5 m/s2.

about 10-19 Joules

The equation for kinetic energy is so the two factors that influence kinetic energy are the object’s mass and its speed (squared). Work causes the initial kinetic energy to change to a final value of kinetic energy .

The amount of grams of each energy source (fat, carbohydrate, and protein) and the amount of energy per gram of each energy source is given on the label. Multiply the grams by the Energy per gram to obtain the Energy.

As the MyPlate icon shows, the five food groups are Fruits, Vegetables, Grains, Protein Foods, and Dairy. The 2015-2020 Dietary Guidelines for Americans emphasizes the importance of an overall healthy eating pattern with all five groups as key building blocks, plus oils.

A calorie is a unit that is used to measure energy. The Calorie you see on a food package is actually a kilocalorie, or 1,000 calories. A Calorie (kcal) is the amount of energy needed to raise the temperature of 1 kilogram of water 1 degree Celsius.

27 Foods That Can Give You More Energy

1. Bananas. Bananas may be one of the best foods for energy.
2. Fatty fish. Fatty fish like salmon and tuna are good sources of protein, fatty acids, and B vitamins, making them great foods to include in your diet.
3. Brown rice. Brown rice is a very nutritious food.
4. Sweet potatoes.
5. Coffee.
6. Eggs.
7. Apples.
8. Water.

Fats and ethanol have the greatest amount of food energy per mass, 37 and 29 kJ/g (8.8 and 6.9 kcal/g), respectively. Proteins and most carbohydrates have about 17 kJ/g (4.1 kcal/g).
