representing motion

Final position minus the initial position is called 

• displacement
• distance
• magnitude
• time interval

_____ is an objects position at a particular instant.

• final position
• instantaneous position
• new position
• real position

What is the resultant of two displacement vectors having the same direction?

• The resultant is the sum of the two displacements having the same direction as the original vectors.
• The resultant is the difference of the two displacements having the same direction as the original vectors.rs
• The resultant is the sum of the two displacements having the direction opposite to the direction of the original vectors.
• The resultant is the sum of the two displacements having the direction perpendicular to the direction of the original vectors.
