1. a vector of strength
force refers to what can be done to an object that is moving or still, objects that are. Movement speed up or slow down or change direction of movement of the object
. There are 2 types of physical quantities is
1. Vector quantities. Refers to the quantity that has both magnitude and direction, such as strength, speed, weight
2. Larnaca is a quantity means notke, one size. There is no direction, such as power, volume, area, time, temperature, rate of speed vector of writing
. Use the length of the straight line represents the size of the force and the direction of the arrows shown strong
.2. motion in one dimension, motion 2.1 in a straight line, divided into 2
- Motion in a straight line going the same direction throughout, such as throwing objects up to direct cars. Moving forward in a straight line.
-The movement in a straight line, but had to move back in the direction, such as a vehicle to slide forward in a straight line. When the car is turning back the direction. Make the movement direction opposite to each other
2.2 speed acceleration and a delay in the movement of an object
- Speed motion of an object is the object moving in 1 unit of time
. -Acceleration motion refers to the increased speed in 1 unit of time, such as an object to fall from that height in vertical
. -A delay in the movement of an object refers to the reduced speed in 1 unit of time, such as throwing it straight into the sky
3. Various types of motion in everyday life
3.1 circular motion refers to the movement of objects in a circle around the Center. Occurs because the object is being moved to travel always in a straight line, but while it has a tensile strength material into the center of the circle is called a. Make an object moving in a circle around the Center, such as the orbit of the Moon around the Earth
. 3.2 motion of an object in motion belonged as a parallel object with the surface of the Earth, such as cars, that are sailing on roads
3.3. Horizontal motion trajectory curve moves at a mixture of motion in vertical and in horizontal Plains
