Speed, Velocity, Acceleration

Front

What is speed?

Back

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

Front

What is the formula for calculating speed?

Back

Speed = Distance / Time.

Front

What is average speed?

Back

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

Front

What is velocity?

Back

Velocity is the speed of an object in a specific direction.

Front

How is velocity different from speed?

Back

Speed is a scalar quantity (only magnitude), while velocity is a vector quantity (magnitude and direction).

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity per unit of time.

Front

What are the units of acceleration?

Back

The units of acceleration are meters per second squared (m/s²).

Front

What does it mean to accelerate?

Back

To accelerate means to increase or decrease the speed of an object or change its direction.

Front

What is the average speed of a jogger who runs 4,000 m in 0.5 h?

Back

8000 m/h.

Front

What two things must you know to determine speed?

Back

Time and distance.
