HEAT TEMPERATURE AND EXPANSION
In this unit we will learn some concepts like heat, temperature, thermal expansion, thermal energy and phases of matter. Moreoversome misconceptions about heat and temperature will be explained. Since they make confusions in many students’ mind, we give more importance on this subject. In daily life sometimes we use them interchangeably however, in physics they are totally different concepts.

PROPERTIES OF MATTER
Matter
Everything around us has mass and volume and they occupy space, and we called them as matter. It can be in four sate, like solid, liquid, gas and plasma. We will talk about main properties of matter in this unit like, mass, volume, density, elasticity, inertia...Etc. You can classify matters with their physical or observable properties and chemical or unobservable properties, for example their smells, colors, shapes give you an idea about it. On the contrary unobservable properties like conductivity of the matter cannot be understood from appearance or smells of the matter.
OPTICS
Optic is one of the branch of physics which deals with the light and properties of it. We know that light shows both the particle and wave characteristics. However, in this unit we will learn the particle characteristics of the light. Some of the topics will be covered in this unit are; reflection and refraction of light, plane mirrors, concave and convex mirrors, reflection of light from the mirrors, prisms and behavior of light in different mediums.
ROTATIONAL MOTION
Rotational motion or we can say circular motion can be analyzed in the same way of linear motion. In this unit we will examine the motion of the objects having circular motion. For example, we will find the velocity, acceleration and other concepts related to the circular motion in this section. Uniform circular motion is one of the example of this subject. In uniform circular motion speed of the object is always constant and direc
tion is changing. Thus, velocity of the object is changing and as a result object has acceleration
tion is changing. Thus, velocity of the object is changing and as a result object has accelerationMomentum with Examples
MOMENTUM
Look at the given pictures. If both the car and the truck have same speed, which one can be stopped first? Of course all you say, it is hard to stop truck relative to car. Well, what is the reason making car stop easier? They have same speed but different masses. Can mass effect the stopping time or distance? The answer is again YES! It is hard to stop heavier objects. What we are talking about so far is momentum.
Energy, Work, Power
In this unit we will deal with the energy, mechanical energy, potential energy, kinetic energy, conservation of energy theorem. Moreover, work and power also discussed in this unit. We will try to give examples related to each topic.
