5.Distance, Time

## 2. In physics, motion is a change in position of an object over time. Motion is described in terms of displacement, distance,

velocity,acceleration, time, and speed.

## 3. Types of motion

1.Uniform motion2.Linear motion

3.non-uniform motion

4.Circular motion

4.Projectile motion

5.Elliptic motion

6.Accelerated and decelerated motion

7.Motion with constant acceleration or

deceleration

## 4.

If the body moves equally alongthe same length, the motion is

called a uniform motion.

## 5.

If the body moves in an equally distinct time, it iscalled non-uniform motion.

2-1. Speed• Definitions:

– Speed

• The rate at which something moves a given distance.

• Faster speeds = greater distances

– General formula for speed:

• Speed = distance / time

• Abbreviations commonly used:

d = distance t = time v = speed

v = d/t

2-1. SpeedAverage speed is the total

distance traveled by an

object divided by the

time taken to travel that

distance.

Instantaneous speed is

an object's speed at a

given instant of time.

## 14.

2-2. VectorsMagnitude of a quantity

tells how large the

quantity is.

Scalar quantities have

magnitude only.

Vector quantities have

both magnitude and

direction.

## 15.

2-2. VectorsVelocity is a vector quantity that includes both speed and

direction.
