1. Basic Concepts of Kinematics

1.1. The kinematics is the study of types of movement that a body can have and its mathematical description.

1.2. This study allows us to predict what happens to a body if it continues with the same conditions of movement in later times at the moment considered as "initial."

1.3. This way of predicting behavior of objects can be appplied to various phenomena of nature, for that reason, the study of movement has gained a preonderant importance.

2. Definitions

2.1. Movement:

2.1.1. Is the change of position of a body in space and through time.

2.2. Distance:

2.2.1. The space traveled by the body during the change of position.

2.3. Displacement:

2.3.1. Distance traveled in a straight line from an initial position to an end position.

2.4. Velocity:

2.4.1. Relationship between the displacement that travels an object and the time spent on it.

2.5. Speed:

2.5.1. Distance traveled per unit of time. Relationship between the distance traveled by the body and the time it takes to travel it.

2.6. Acceleration:

2.6.1. Refers to the change in velocity (or speed) of a body during its movement.

2.7. Mass:

2.7.1. Measure of the property of all bodies to resist in their state. Measure of inertia of the bodies.

2.8. Force:

2.8.1. Every agent capable of producing a change in the movement of bodies.

2.9. Weight:

2.9.1. Force with which the Earth attracts a body due to the action of gravity

3. Measuring Instruments

3.1. In scientific research, the measurement of physical magnitudes associated with various phenomena is required.

3.2. When we speak of measurements, we refer to the action of measuring, that is, determine in an experimental way the value of a physical quantity using the appropiate instruments and devices.

3.3. Some of the common instruments used in daily life are:

3.3.1. Test tube

3.3.2. Chemical thermometer

3.3.3. Ruler

4. Lenght Measuring Instruments

4.1. In Antiquity, the human being used tools to identify the dimensions of objects and places.

4.2. Over time, other instruments were used, from which we can trace its origins from Ancient Rome, where Romans used leather belts marked with conventional measuring units for that time and place,

4.3. Currently, there are more accurate measuring instruments, one very used is the nonio (also known as caliper):

5. Mass Measuring Instruments

5.1. To measure the mass of the objects the balance are used.

5.2. Obviously at the present there are other instruments to measure mass, such as analitycak balances, electronic and others.

6. Instruments for Measuring Time

6.1. We can consider that, since antiquity, the human has used different means to measure time, such as the shadow cast by the sun, candles, hour glass, among others.

6.2. More precise and everyday instruments were designed, such as the mechanical clock, the quartz clock, the digital chronometer and the atomic clock.

7. Safety Regulations when Using Measuring Instruments

7.1. These are a few of the safety measures every student must follow when using measuring instruments in the laboratiry.

7.1.1. 1. Pay attention to the teacher or laboratory assistant.

7.1.2. 2. Pay attention to what you are doing, do it carefully and with the material handling of the laboratory instruments that will be used in the programmed practice.

7.1.3. 3. Within the laboratory you should wear the tight clothes,

7.1.4. 4. Your teacher or the personnel in charge of the laboratory should be supervising the practice at all times and should never be absent,
