Velocity, Speed, and Acceleration

Front

What is Speed?

Back

Speed is the distance traveled per unit of time, typically measured in miles per hour (mph) or kilometers per hour (km/h). It does not include direction.

Front

What is Velocity?

Back

Velocity is the speed of an object in a specific direction. It is a vector quantity, meaning it has both magnitude and direction.

Front

What is Acceleration?

Back

Acceleration is the rate of change of velocity of an object. It occurs when an object speeds up, slows down, or changes direction.

Front

How is Speed calculated?

Back

Speed is calculated using the formula: Speed = Distance / Time.

Front

What is the difference between Speed and Velocity?

Back

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

Front

What is an example of Speed?

Back

A car traveling at 60 km/h on a straight road.

Front

What is an example of Velocity?

Back

A car traveling at 60 km/h to the north.

Front

What is an example of Acceleration?

Back

A car increasing its speed from 30 km/h to 60 km/h in 5 seconds.

Front

What units are commonly used to measure Speed?

Back

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

Front

What is the formula for calculating Acceleration?

Back

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