Distance/Displacement/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.

Front

Define speed.

Back

Speed is the rate at which an object covers distance, calculated as speed = distance/time.

Front

What is velocity?

Back

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

Front

What is the formula for calculating distance?

Back

Distance = Speed x Time.

Front

If a runner completes a 400 meter lap and returns to the starting point, what is their displacement?

Back

0 meters.

Front

What does a flat line on a distance-time graph indicate?

Back

The object is not moving.

Front

What does a steeper slope on a distance-time graph represent?

Back

A higher speed.

Front

If two objects are moving at the same speed but in different directions, are their velocities the same?

Back

No, their velocities are different because velocity includes direction.

Front

What is the unit of speed in the metric system?

Back

Meters per second (m/s).

Front

How do you calculate average speed?

Back

Average speed = Total distance traveled / Total time taken.
