Review: Speed, Distance, Displacement, and Time

Front

What is speed?

Back

Speed is the distance traveled per unit of time, typically measured in meters per second (m/s).

Front

How do you calculate speed?

Back

Speed = Distance / Time.

Front

What is the formula for distance?

Back

Distance = Speed x Time.

Front

What is displacement?

Back

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

Front

How is displacement different from distance?

Back

Distance is the total path length traveled, while displacement is the straight-line distance between two points.

Front

What units are commonly used to measure speed?

Back

Common units for speed include meters per second (m/s) and kilometers per hour (km/h).

Front

If a car travels 150 km in 3 hours, what is its speed?

Back

Speed = 150 km / 3 hours = 50 km/h.

Front

What is the relationship between speed, distance, and time?

Back

Speed is directly proportional to distance and inversely proportional to time.

Front

If a runner completes a 400 m lap in 50 seconds, what is their speed?

Back

Speed = 400 m / 50 s = 8 m/s.

Front

What is average speed?

Back

Average speed is the total distance traveled divided by the total time taken.
