Distance Time Graph

This graph represents (a)  

• Constant Speed
• Acceleration
• Not moving

Answer explanation

The graph shows a straight line, indicating that the object is moving at a constant speed. This means the speed does not change over time, which aligns with the correct answer, 'Constant Speed'.

This graph represents (a)  

• Constant speed
• Acceleration
• Not moving

Answer explanation

The graph shows a horizontal line, indicating that there is no change in position over time. This means the object is not moving, which is why 'Not moving' is the correct answer.

Segment A-B The bus is (a)   .

• at rest
• returning (to original position)
• moving forward

Answer explanation

The correct answer is 'at rest' because Segment A-B indicates that the bus is not moving. The other options suggest movement, which contradicts the context of the segment.

The bus is (a)   . (Segment C-D)

• at rest
• returning (to original position)
• moving forward

Answer explanation

The bus is described as 'at rest' in segment C-D, indicating it is not moving. The other options suggest movement, which contradicts the statement. Therefore, 'at rest' is the correct choice.

(a)   and time are necessary for calculating speed.

• Mass and time
• Temperature and mass
• Mass and distance
• Distance and time

Answer explanation

To calculate speed, you need to know how far an object has traveled (distance) and how long it took to travel that distance (time). Therefore, the correct measurements for calculating speed are distance and time.
