MOTION

is defined as the movement of an object. exhibited by a change in position. may be described by specifying how far something has traveled in changing position and time.

TRANSLATORY MOTION -the particle moves from one point in space to another. Example: A car moving on a straight Example: A car moving on a straightroad.

RECTILINEAR MOTION -is the motion of an object traveling in a straight path. ex: ex: A car going in a straight line. An apple falling from a tree.

CURVILINEAR MOTION -is an object that traveling in a curved path. Earth’s orbit Earth’s orbit ANGULAR MOTION -is an object traveling at a certain angles.

ROTARY MOTION -the particles of the body describe concentric circles about the axis of motion. -the particles of the body describe concentric circles about the axis of motion. VIBRATORY MOTION OR OSCILLIATORY MOTION -the particles move to and fro about a fixed point. Simple Pendulum

PROJECTILE MOTION an object thrown with an initial horizontal velocity and acted upon by the earth’s pull of gravity.an object thrown with an initial horizontal velocity and acted upon by the earth’s pull of gravity. A projectile travels in a curved path called the trajectory.A projectile travels in a curved path called the trajectory. Projectile includes objects that are thrown horizontally as well as objects that are projected at an angle such as: Making a free thrown in basketballMaking a free thrown in basketball Serving a volleyballServing a volleyball Batting a baseballBatting a baseball Dropping a package or relief goods from a helicopter.Dropping a package or relief goods from a helicopter.

KINEMATICS -the study that deals with the description of motion. -It uses the following basic concepts of motion: Distance Distance -is the total path length traversed by an object moving from one location to another. -is a scalar quantity which has only magnitude while displacement is a vector quantity which has both magnitude and direction. Displacement Displacement -is the separation of that point. Speed Speed Velocity Velocity Acceleration Acceleration

SCALARS AND VECTORS

SCALAR QUANTITY - is a quantity that is described by a magnitude. Some examples of scalar quantities are the following: 40 kg, which describes a mass40 kg, which describes a mass 30 min, which tells time30 min, which tells time 5 km, which shows distance5 km, which shows distance 27 degrees C, which gives temperature.27 degrees C, which gives temperature.

One characteristic of scalar quantities is that they add up or subtract like ordinary numbers. For example, the quantity length l 1 = 6 m and another one, l 2 = 4m. The sum of these two lengths is given as l=l 1 +l 2 = 6 m + 4 m = 10 m. The scalar quantity, length, has a magnitude of 10 and has the unit meters represented by m.

VECTOR QUANTITY -is a quantity that is completely described by both magnitude and direction. Some examples of vector quantities are the following: 80 km/ h E, which tells the velocity of a vehicle ( the magnitude is 80 km/ h and the direction is East) 20 N upward, which describes a force of 20 N ( magnitude) directed upward 1 m/s 2 to the right, which expresses the acceleration of a moving object with magnitude of 1 m/s 2 directed to the right. Vector quantities are important in the study of physics. If scalar quantities follow ordinary arithmetic rules, vector quantities do not. This is one important characteristics of vectors.

SAMPLE PROBLEM On his way to school, Jed traveled 100 m North, 300 m East, 100 m North, 100 m East 100 m North. Find the total distance traveled by Jed.Find the total distance traveled by Jed.Solution: d t = d 1 + d 2 + d 3 + d 4 + d 5d t = d 1 + d 2 + d 3 + d 4 + d 5 = 100 m m m m +100 m d t = 700 m

FALLING OBJECTS Free Fall- It is the motion of falling bodies and the factors that affect their rate of fall. Examples: Examples: A coin that was tossed goes up because the coin isA coin that was tossed goes up because the coin is moving away from the earth. moving away from the earth. The mango that falls down because it is pulled by the earthThe mango that falls down because it is pulled by the earth a mango is moving toward the center of the earth.
