The universe consists of matter in motion.  To introduce the properties of motion (position, speed and velocity, and acceleration.)  To use the metric. - ppt download

1. Motion is a change in the object’s position with respect to time 2. Motion can be along straight line (horizontal or vertical) or curve 3. Direction is sometimes important The Greek philosopher divided it into to two kinds. 1)Natural motion 2)Violent motion 1)Natural motion 2)Violent motion
The universe consists of matter in motion
 To differentiate between speed and velocity.  To differentiate between velocity and acceleration.  To learn how to analyze problem statements and to translate the information into a recipe, and  To develop a problem solving skill..
Motion can be along straight line (horizontal or vertical) or curve 3. Direction is sometimes important The Greek philosopher divided it into to two kinds. 1)Natural motion 2)Violent motion 1)Natural motion 2)Violent motion.
For example, i.the downward motion of a falling stone and ii.the rise of smoke.
For example, i.the motion of a cart pulled by a horse and ii.the motion of an arrow by a stretched bow..
 A scalar quantity is a quantity that has magnitude only and has no direction in space Examples of Scalar Quantities:  Length  Area  Volume  Time  Mass Scalar
 A vector quantity is a quantity that has both magnitude and a direction in space Examples of Vector Quantities :  Displacement  Velocity  Acceleration  Force Vector
 MKS meter-kilogram-second  CGS centimeter-gram-second  FPS foot-pound-second
Mass of human is 78 kg = kg 2. Diameter of earth is m = m 3. Length of a virus is cm = cm.
Describes how fast an object is moving. Describes how fast an object is moving.
What is your average speed  A car has an average speed of 10m/sec. How far will it be traveling in 10 second .
Types of Motion Uniform (constant)motion: Straight line motion in which equal distances cover during any successive equal time intervals
Non-Uniform Motion Motion on a curve, and Occur when successive displacements/distances are not equal at equal time intervals Example- falling objects - Can be represented graphically
Acceleration S.I unit of acceleration is m/sec 2
