HW1.3

What is this graph showing?

• The object is moving away from starting point at a constant speed

• The object is moving back towards the starting point at a constant speed

• The object is increasing its velocity

• The object is decreasing its velocity

What does this graph represent?

• Constant speed
• Acceleration
• Not moving

The picture of the position vs. time graph shows an object that is...

• speeding up

• moving at a constant speed

• not moving

• slowing down.

What is the average velocity of this object between 0 and 4 seconds in m/s? (Do not write in units).
