2. Types of motion in a human body
• Hand - uniform motion
• Muscles - non uniform motion
• gland - uniform motion
• Tongue and Teeth – non uniform motion
• Breathing – uniform motion
• Heart – uniform motion
3. Distance
•Distance is the total length covered
by a moving object independent of
the direction of motion .
•Distance is a scalar quantity .
4. Displacement
•Displacement is the distance
measured in a straight line and in a
specified direction .
•Displacement is a vector quantity .
5. Speed
• Speed is defined as rate of change of
distance.
• In other words , speed is the distance
moved per unit time . It tells you how
fast or slow the object is moving
6. Velocity
• Velocity is the rate of change of
displacement .
• It is a speed in a specified direction .
• It tells us the magnitude and direction
that the object is moving
7. Acceleration
• Acceleration describes of the rate of change of
velocity with time .
• Acceleration is when an object
> Speed up
> Slow down
>changes direction
• Like velocity , acceleration is a vector quantity.
