Nora, Olivia, and Zoe are discussing their physics homework. Can you help them figure out what the slope on a position-time graph represents?

• The velocity of the object

• The acceleration of the object

• The position of the object

• The time taken by the object

During a science experiment, Oliver and Grace observe a horizontal line on a position-time graph. What does this line represent?

• An object with constant velocity

• An object with constant acceleration

• An object at rest

• An object with changing velocity

During a science experiment, Avery and Rohan observe a position-time graph. What does a curved line on this graph indicate?

• An object with constant velocity

• An object with constant acceleration

• An object with changing velocity

• An object at rest

Harper and Aiden are racing their toy cars. What does a positive slope on their position-time graph represent?

• An object with negative velocity

• An object with positive velocity

• An object at rest

• An object with constant acceleration

During a science experiment, Zoe and Samuel observe a line that curves downward on a position-time graph. What does this represent?

• An object with negative acceleration
