Alexis is riding her bike around town. She travels 43.2 m to the right, and then turns around to bike an additional 30 m to the left. Determine the velocity of Alexis's bike ride if it takes her 39.4 seconds to complete her motion.

• 2 m/s to the right

• 2 m/s to the left

• 0.3 m/s to the right

• 0.3 m/s to the left

What does a horizontal line on a distance vs time graph tell us about the motion of the object?

• Slowing down

• Speeding up

• Standing still

• In free fall

What does a horizontal line on a velocity vs time graph tell us about the motion of an object?

• Constant speed

• Standing still

• Slowing down

• Speeding up

What does a constant velocity do tour our acceleration?

• Acceleration increases

• Acceleration decreases

• Acceleration is zero

• Acceleration is not affected by velocity

• Slow the object down

• Change the object's direction

Imagine Mr. Gomez spinning a yo-yo in a circular motion with a constant speed. Would the yo-yo have an acceleration during its motion?

• Yes; the displacement is changing, resulting in a changing acceleration

• No; objects at a constant speed always have zero acceleration

• No; acceleration does not apply to centripetal (circular) motion

• Yes; the direction is constantly changing, which changes the acceleration
