Distance Displacement Speed and Velocity Review

Front

What is the definition of distance?

Back

Distance is the total length of the path traveled by an object, regardless of direction, measured in meters.

Front

What is the definition of displacement?

Back

Displacement is the shortest distance from the initial to the final position of an object, including direction, measured in meters.

Front

What is the difference between distance and displacement?

Back

Distance is a scalar quantity (only magnitude), while displacement is a vector quantity (magnitude and direction).

Front

What is speed?

Back

Speed is the rate at which an object covers distance, calculated as distance divided by time, measured in meters per second (m/s).

Front

What is velocity?

Back

Velocity is the rate at which an object changes its position, calculated as displacement divided by time, and includes direction, measured in meters per second (m/s).

Front

How do you calculate distance traveled if speed and time are known?

Back

Distance = Speed × Time.

Front

If a dog walks at a speed of 3 m/s for 4 seconds, how far does it travel?

Back

Distance = 3 m/s × 4 s = 12 m.

Front

How do you calculate displacement?

Back

Displacement = Final Position - Initial Position.

Front

If Mr. Riker walks 8 m west and then 6 m east, what is his displacement?

Back

Displacement = (8 m west) + (6 m east) = 2 m west.

Front

What is the formula to calculate time if distance and speed are known?

Back

Time = Distance ÷ Speed.
