Speed

Front

What is speed?

Back

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

Front

What is the formula to calculate speed?

Back

S = d/t, where S is speed, d is distance, and t is time.

Front

What is average speed?

Back

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

Front

If a runner completes a 400 meter race in 100 seconds, what is their average speed?

Back

4 m/s (calculated as 400 meters / 100 seconds).

Front

What is instantaneous speed?

Back

Instantaneous speed is the speed of an object at a specific moment in time.

Front

What is the difference between average speed and instantaneous speed?

Back

Average speed is calculated over a period of time, while instantaneous speed is measured at a specific point in time.

Front

If a car travels 150 kilometers in 2 hours, what is its average speed?

Back

75 km/h (calculated as 150 km / 2 hours).

Front

What units are commonly used to measure speed?

Back

Common units include meters per second (m/s), kilometers per hour (km/h), and miles per hour (mph).

Front

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

Back

Distance = Speed x Time (d = S x t).

Front

How do you convert speed from km/h to m/s?

Back

To convert km/h to m/s, divide the speed by 3.6.
