Displacement, Speed, and Velocity Concepts

What is displacement?

• Displacement is the shortest distance from the initial to the final position of an object, along with the direction.
• Displacement is the total distance traveled by an object regardless of direction.
• Displacement refers to the change in speed of an object over time.
• Displacement is the distance covered by an object in a straight line without considering direction.

1. Identify the equation used to determine the average speed of an object.

• average speed = displacement / time taken

• average speed = total distance / total time
• average speed = total distance + total time
• average speed = total time / total distance

1. Identify the equation used to determine the average velocity of an object.

• average velocity = (final position - initial position) / (final time - initial time)
• average velocity = (final time - initial time) / (final position - initial position)
• average velocity = (final position + initial position) * (final time + initial time)
• average velocity = (initial position + final position) / 2

1. Compare instantaneous speed to constant speed.

• Instantaneous speed is the average speed over a long distance.
• Constant speed varies at different moments during motion.
• Instantaneous speed is variable and measured at a specific moment, while constant speed is uniform and maintained over time.
• Instantaneous speed is always constant and does not change over time.

6 meters south then

10 meters north.
