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 endpoint, including direction.

Front

Define speed in terms of distance and time.

Back

Speed is defined as the distance traveled divided by the time taken, expressed as Speed = distance/time.

Front

What is velocity?

Back

Velocity is the speed of an object in a specific direction, defined as Velocity = displacement/time.

Front

If a runner completes a lap around a track and returns to the starting point, what is their displacement?

Back

The displacement is 0, as the starting and ending points are the same.

Front

What is the formula for calculating average speed?

Back

Average speed = total distance traveled / total time taken.

Front

How does the direction of motion affect velocity?

Back

Velocity includes direction; changing direction while maintaining speed changes the velocity.

Front

What is the unit of speed in the metric system?

Back

The unit of speed in the metric system is meters per second (m/s).

Front

What is the total distance traveled if a bird flies 200 km north, then 300 km north, and finally 250 km north?

Back

The total distance traveled is 200 km + 300 km + 250 km = 750 km.

Front

What is an example of a situation where distance and displacement are not equal?

Back

If a person walks in a circle and returns to the starting point, the distance is the circumference of the circle, while the displacement is 0.

Front

What does it mean if an object has a constant speed?

Back

It means the object covers equal distances in equal intervals of time, regardless of the direction.
