1. the slope of this graph...................

• 1. Is positive and the unit is (current /ohms )

• 1. Is negative and the unit is (A /ohms )

• 1. Is zero and the unit is (current /ohms )

A line on a graph has points (2 sec, 6 m) and (4 sec, 12 m). Calculate the slope of the line.

• slope=(12-6)/(4-2)

  = 3 m/s

• slope=(12-6)/(4)

  = 1.5 m/s

• slope=12/2

  = 6 m/s

• slope=(4-2)/(6-12)

  = 0.3 m/s

• Acceleration

• Direction

• Displacement

• Motion

Motion is any change in __________.

• Time

• Speed

• Velocity

• Position
