Energy Questions and Answers (Q&A)

There are different types of energy in this world. One type is called potential energy. This type of energy is the held energy of an object before usually it does something in movement. One example of this is the stretching of a rubber band or the stretching of a bow in order to shoot an arrow.

The point at which the item is stretched shows its potential energy. When the person releases their grip on the item, the energy changes. The person may let go of the arrow and the bow in order for the arrow to shoot forward.

The person may let the rubber band go and it shoots back to its original shape. These are the best examples of increasing an objects’ potential energy.

"Energy Is the Ability to Do Work." Energy can be found in a number of different forms. It can be chemical energy, electrical energy, heat (thermal energy), light (radiant energy), mechanical energy, and nuclear energy. Stored and Moving Energy.

A coenzyme is a small, organic, non-protein molecule that binds with or attaches itself to a protein molecule to form an active enzyme. Enzymes are found in almost all living organisms and have very important roles, for example, to aid in digestion. An active enzyme’s purpose is to facilitate and speed up a chemical reaction.

Vitamins B1, B2, and B6 are examples of water soluble enzymes that serve as coenzymes. Another example of an enzyme is Amylase. Amylase helps change starches into sugars.

When an object like a ball changes direction or is stopped, this is caused by inertia. Specifically, inertia is the when an object continues in its same path and it won’t stop moving until another force causes it stop moving or change directions. The history of inertia began hundreds of years ago during 335 BC or a few years later. Aristotle is believed to have come in contact with the theory of inertia.

With his concept of motion, Aristotle described his idea that sometimes objects may become projectiles. These projectiles will continue to move unless they come to rest or some outside force causes it to stop or change directions. Other scientists continued and built on this idea including Jean Buridan.

The answer to this is C. The formula that you should follow for this is the amount of work that is done on your car is equal to KE. The formula for this is Fnetd. This will then be multiplied by 50 so that the proper answer will be given. The equation that you are going to use should be Fnet = -1.2 x 105J / 50 m = -2.4 x 103 N.

If you would encounter questions that are similar to this again, you will know how to answer them even if the numbers are going to be different as long as you know the formula. It is best that you know the formula for the different questions that will be provided.

How is the answer of this question conduction (I have to write at least 10 words so i exaggerated)

1 Answer

The correct answer is option B – 75 joules Since kinetic energy= 0.5mv^2 KE1 = (0.5(50)(2^2) = 100 KE2 = (0.5(50)(1^2) = 25 To calculate the KE at the two different velocities then subtract them. KE = (0.5(50)(2^2)) - (0.5(50)(1^2)) = 100-25 = 75 kgm/s^2 Keep in mind that kilogram meters per second squared (kgm/s^2) is the same as Joules ~ 75 Joules.
