8. It is a continues change in position of an
object with respect to the reference point
Define as change of position in a given
time interval
Reference point - is a place or object used
for comparison to determine if something
is in motion.

Two types of Quantities need to consider:
1. Scalar Quantities - are quantities that are fully described by a
magnitude (or numerical value) alone.
2. Vector Quantities - are quantities that are fully described by both a
magnitude and a direction.

24.  Speed is a scalar quantity that refers to "how fast an
object is moving." Speed can be thought of as the rate at
which an object covers distance.
 Speed shows the relationship of distance and time.
 SI unit of speed is m/s
 Unit measurement may be m/s km/h and mi/h
 Average speed is calculated by dividing the total distance that
something has traveled by the total amount of time it took it to
travel that distance.

moves in one direction.

30.  is a vector quantity that is defined as the rate at which an
object changes its velocity. An object is accelerating if it is
changing its velocity.
 The definition of acceleration is different from speed
and velocity. Acceleration is defined as the “change in
velocity”. Based on the definition, there must be change
in the velocity of the object. This change can be in the
magnitude (speed) of the velocity or the direction of the
velocity. In daily life, we use the term acceleration for
the speeding up objects and decelerating for the slowing
down objects.
 Acceleration the numerical value is in positive while in
deceleration the numerical value is in negative

31. What's the formula for acceleration

32. This equation can be used to calculate the acceleration of the
object whose motion is depicted by the velocity-time data table
above. The velocity-time data in the table shows that the object
has an acceleration of 10 m/s/s. The calculation is shown below.

in 2.0s What is the average acceleration

33. Sample 2. A car slows down from 15m/s to 8 m/s in 3.5s What is
the acceleration of the car ?
