Distance, Displacement, Speed, Velocity and Acceleration

Front

What is distance?

Back

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

Front

What is displacement?

Back

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

Front

What is speed?

Back

Speed is the rate at which an object covers distance, calculated as distance divided by time.

Front

What is velocity?

Back

Velocity is the rate at which an object changes its position, including direction; it is speed with a direction.

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity of an object with respect to time.

Front

How do you calculate speed?

Back

Speed = Distance / Time.

Front

How do you calculate acceleration?

Back

Acceleration = (Final Velocity - Initial Velocity) / Time.

Front

What is the unit of speed?

Back

The unit of speed is meters per second (m/s).

Front

What is the unit of acceleration?

Back

The unit of acceleration is meters per second squared (m/s²).

Front

If a car travels 100 m in 5 seconds, what is its speed?

Back

Speed = 100 m / 5 s = 20 m/s.
