:

Linear Ho
rizontal Motion (Kinematics Equations)


-

Communicate position of a object
-
point in a
RF

-

Distinguish between
distance
and
displacement

-

Derive kinematics equation for position and velocity

Q:

a)

Describe how an object can move, if it travels 7 m, but its displac
ement is only 5 m.

b)

Describe how an object moves if it travels 9 m, but its displacement is 0.

c)

Can an object move such that its displacement is 9 m, to the right, but the distance traveled is 0?
