1.1.2  Bodies do not always move at the  same speed


When bodies move at a constant speed we say that they have a UNIFORM movement

If the speed at which the bodies move is not constant, we say they have a VARIED or NON-UNIFORM movement.
We can also say the movement is ACCELERATED or DECELERATED

It always goes at the same speed: UNIFORM
It goes slower and slower: VARIED (it decelerates)

Uniform Movement

 

Varied movement (decelerated)

 
Different types of movement
 . Trajectory and speed
 . Find out how it moves
Uniform movement
 . Constant speed
 . How fast is it going?
 . Data table
 . Circular
 . Compare the speeds
Varied movements
 . How fast is it going?
Representations of movements
 . Vectors
 . Tables and graphs of Uniform Mov.
