Слайд 4
If the body moves equally along the same length,

the motion is called a uniform motion.


If the body moves equally along the same length, the motion is called a uniform motion.

Слайд 5If the body moves in an equally distinct time, it

is called non-uniform motion.

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

Слайд 112-1. 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

Слайд 132-1. Speed
Average 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.

Слайд 142-2. Vectors
Magnitude of a quantity tells how large the quantity

is.
Scalar quantities have magnitude only.
Vector quantities have both magnitude and

direction.
