Speed and Velocity

Front

What is the definition of speed?

Back

Speed is the distance traveled per unit of time, typically expressed in units such as meters per second (m/s) or miles per hour (mi/hr).

Front

What is the definition of velocity?

Back

Velocity is the speed of an object in a specific direction, expressed in units such as meters per second (m/s) or miles per hour (mi/hr) with a directional component.

Front

How do speed and velocity differ?

Back

Speed is a scalar quantity that only considers magnitude, while velocity is a vector quantity that includes both magnitude and direction.

Front

What is required to calculate speed?

Back

To calculate speed, you need to know the distance traveled and the time taken.

Front

What is an example of a scalar quantity?

Back

An example of a scalar quantity is speed, as it only has magnitude.

Front

What is an example of a vector quantity?

Back

An example of a vector quantity is velocity, as it has both magnitude and direction.

Front

What does it mean for an object to be in motion?

Back

An object is in motion if its position changes relative to another object over time.

Front

What is the formula for calculating speed?

Back

The formula for calculating speed is: Speed = Distance / Time.

Front

What is the significance of direction in velocity?

Back

Direction is significant in velocity because it indicates the path along which an object is moving, distinguishing it from speed.

Front

What is the unit of measurement for velocity?

Back

The unit of measurement for velocity is typically meters per second (m/s) or kilometers per hour (km/h).
