Essential Physics Terms To Know For Your Test

Physics is a difficult subject, but it doesn’t have to be. Knowing these basic physics terms will help you understand the test and know what information to look for in each question.

Potential Energy

Potential Energy is the stored energy of an object due to its position relative to other objects.

For example, a ball at the top of a hill has more potential energy than one at the bottom because it can roll down and do work (move other objects). The force required for this change in position is called “gravitational potential energy”. The amount of gravitational potential energy depends on how high up on the hill you are standing and how far away from Earth’s center you are located.

If you throw something straight up into space with no air resistance or friction then it will travel all around earth before returning back again after an indefinite amount of time–the distance travelled will be equal to 2pr where r is half circumference length around Earth’s surface (or circumference) so if we assume radius 1m then total distance travelled would be 2 x p x R = 4pR

Kinetic Energy

Kinetic energy is the energy that an object has due to its motion.

It can be calculated as:

K = 1/2 * m * v^2

Gravitational Force

Gravitational force is the attraction between two objects due to their masses. The strength of this force is proportional to the product of their masses and inversely proportional to the square of the distance between them. Gravitational force is always attractive, no matter what direction you’re moving in or what kind of motion you’re going at (up, down, sideways).

Newton’s Second Law of Motion

Newton’s second law of motion states that the acceleration of an object is directly proportional to the force … Continue reading >>>>

Advanced Engineering Mechanics

Engineering Mechanics is a branch of engineering that deals with the behavior of isolated systems, as well as systems consisting of many parts. The field has several sub-divisions, each of which covers a specific aspect of mechanics. Perhaps the most significant divisions are statics and dynamics.


Statics is the study of systems in equilibrium. It is concerned with forces, their effects and their relations to each other. Forces can be grouped into three categories:

  • Axes – These are lines that pass through the center of mass and are perpendicular to the plane of rotation (momentum). An axis can be thought of as an imaginary line that connects two points on an object or system (such as a rod).
  • Moments – A moment is the product of force multiplied by distance from its point of application; it’s represented by an arrow pointing away from this point.
  • Couples – A couple consists of equal and opposite couples acting on different points on an object or system; they’re represented by two arrows pointing toward each other at right angles


If you’ve taken a physics class, you know that dynamics is the study of how objects move. The motion of a body can be described by its position (where), velocity (how fast) and acceleration (how quickly).

In this section we’ll cover Newton’s laws of motion:

Strength of Materials

Strength of materials is the branch of mechanics that deals with the behavior of materials and structures under forces. It is also known as solid mechanics, but this term can cause confusion with liquid or fluid mechanics.

Strength of materials is considered as one of the most fundamental branches of mechanics and it deals with stress, strain and deformation in solids. The main objective behind strength of materials is to determine how much stress … Continue reading >>>>

Are Run Flat Tyres a Good or Bad Choice?

Some leading manufacturers are developing the adaption of using run flat tyres in the line up of their vehicles. This allows some advantages for the owner of the vehicle but like anything it comes with certain disadvantages. The main purpose for this added feature is the ability to drive a short amount of distance after suffering a puncture in the tyre to make it to a service station.

Doesn’t this sound great? You could be driving down the road, following a vehicle, when something falls off the vehicle in front of you and with no time to react. PPUUUUFFF! You don’t have time to change a tire or really don’t want to be out on this busy commute road attempting to fix your problem with motorist wheezing by.

So positive you can find positive aspects to running these tyres. Like having the ability to continue along for a brief amount to time until you can get to a secure service station to create repairs ahead of a blow out occurs. It is considerably a lot easier to maintain clean and have somebody else do the work whilst you wait the brief amount of time for you to get back on the road and on schedule.

Even improved, maybe you happen to be someone that demands the cargo space in the trunk of your car or truck exactly where typically the spare tyre is stored. With these special tyres there shouldn’t be any require to carry a spare together with you. This would allow you to use that most precious cargo room for your private use.

As stated prior to, with anything there are certain disadvantages. To begin with, what in case you are on a trip or commute exactly where the nearest service station isn’t as near as … Continue reading >>>>

Industrial Upkeep Mechanic Resume Examples Developed mechanicRagnarok online mechanic skill buildCar owners place a lot of trust in mechanics to limit maintenance and repairs to what a vehicle needs But when there is a sizable information gap in between automobile owner and mechanic, that trust can be betrayed. If you have a drone, you can grant the effects of haste to your drone for 1 minute as a move action. If you have an exocortex, you can obtain the effects of haste for 1 minute as a move action. When you or your drone has utilised this ability, you can’t use it again till you invest 1 Resolve Point to regain Stamina Points from a ten-minute rest. You need to have the overclocking and hyperclocking mechanic tricks to understand this trick.

Aircraft maintenance technicians (AMTs) are accountable for performing repairs, preventative and routine maintenance on all kinds of aircraft and helicopters. FAA certified aircraft mechanics (also called Airframe & Powerplant mechanics, or A&P mechanics) are in high military, airlines, government, and many other firms are hiring aircraft mechanics.

A number of Roles – Some cars in game have far more than a single Gunner, Loader, and Radio Operator on board in a normal crew complement. If far more than a single crew member in a vehicles have the very same Major Qualification, then the average of their Coaching Levels is employed to establish their joint performance in that function. For example, for a automobile with two Loaders, a single at 50% Training Level, and the other at 100%, their typical Training Level of 75% will apply to the automobile as the Loader’s Successful Training Level in battle mechanics and vehicle efficiency calculations.

Your drone gains resistance to an energy kind of your choice—acid, cold, electrical energy, fire, or sonic—equal to your mechanic level, to a maximum of ten. You can pick this mod multiple occasions. Its effects do not stack every single time you select this mod, it should apply to a different power kind from the list above. On effective completion of Australian context gap instruction and supervised employment, applicants are eligible to apply for a MEM30205 Certificate III in Engineering – Mechanical Trade (Refrigeration and Air Conditioning).

Your exocortex offers you with enhanced combat capacity, granting you proficiency with heavy armor and longarms. At 3rd level, you gain weapon specialization in longarms just as if your class granted proficiency. As a move action throughout combat, you can designate a foe for your exocortex to track. As lengthy as that target is in sight, the exocortex feeds you telemetry, vulnerabilities, and combat techniques, allowing you to make attacks against that target as if your base attack bonus from your mechanic levels have been equal to your mechanic level.
