Understanding One-Dimensional Motion

What is necessary to define the position of an object in one-dimensional motion?

• A stopwatch and a ruler

• An origin point and coordinate axes

• A compass and a map

• A speedometer and an odometer

How does displacement differ from distance?

• Displacement is a scalar, while distance is a vector.

• Displacement measures total path length, while distance measures straight-line distance.

• Displacement includes direction, while distance does not.

• Displacement is always greater than distance.

If you run a full lap around a 400-meter track and end at your starting point, what is your displacement?

• 0 meters

• 200 meters

• 400 meters

• 800 meters

What is the main difference between velocity and speed?

• Velocity is always greater than speed.

• Velocity measures total distance, while speed measures displacement.

• Velocity includes direction, while speed does not.

• Velocity is a scalar, while speed is a vector.

What does acceleration describe in terms of motion?

• The time taken to complete a journey

• The direction of motion

• The change in velocity over time

• The total distance traveled
