Distance/Displacement and Speed/Velocity

Front

What is the difference between distance and displacement?

Back

Distance is the total path length traveled, while displacement is the shortest straight line from the starting point to the ending point.

Front

What does speed measure?

Back

Speed measures how fast an object is moving, calculated as distance traveled over time.

Front

What is velocity?

Back

Velocity is the speed of an object in a specific direction.

Front

If a runner completes a lap around a track, what is their displacement?

Back

The displacement is zero, as they end up at the starting point.

Front

What is the formula for calculating speed?

Back

Speed = Distance / Time.

Front

If you walk 5 km north and then 5 km south, what is your total distance and displacement?

Back

Total distance is 10 km; displacement is 0 km.

Front

What unit is commonly used to measure speed?

Back

Meters per second (m/s) or kilometers per hour (km/h).

Front

If a car travels 120 km in 2 hours, what is its average speed?

Back

Average speed = 120 km / 2 hours = 60 km/h.

Front

What is a scalar quantity?

Back

A scalar quantity has only magnitude, such as distance or speed.

Front

What is a vector quantity?

Back

A vector quantity has both magnitude and direction, such as displacement or velocity.
