Electric cars require enhanced batteries

According to the survey, electric cars are much preferred by motorists than the fueled cars. It is because it can is cheaper. Also, the electric cars are our future cars, and presently, it doesnt have any ideal battery that can help sustain its energy.

.aHuh??..Third Grading: Good bye.! =)

During our 3rd grading period, we discussed about our first topic which is the rotational motion. I learned that when an object in rotational motion is constantly changing its direction of motion, it means that the object is accelerating. If an object’s change in direction of velocity is directed toward the same direction, the acceleration of an object also points toward the same direction.

Our teacher taught us also about momentum. I learned that Momentum can be transferred from one object to another, usually during contact, and this is called the law of conservation of momentum. It states that during an interaction, the total momentum is unchanged or in an isolated system, the total momentum before an interaction is the same as the total momentum after interaction.

In our topic Work, Energy and Power, I learned that they are all related with each other, in a reason that energy is what gives objects the ability to do work, and in order to do work to an object, it requires a force which will be applied to the object to make it move. Power on the other hand is the rate at which work is done, or the amount of work done per unit. =)

Wave power could contain fusion plasma

Researchers at the University of Warwick’s Centre for Fusion Space and Astrophysics and the UK Atomic Energy Authority’s Culham Centre for Fusion Energy may have found a way to channel the flux and fury of a nuclear fusion plasma into a means to help sustain the electric current needed to contain that very same fusion plasma.

my learnings

In physics, I have difficulties sometimes in memorizing  some formulas but i learned a lot.. Every activities given to us seems to be difficult at first, but as time goes by, i found it enjoying and interesting.. =) I learn to calculate using kinematic equations. I also learn what is projectile motions, the three law of motions of Newton and many more.. =)
