Speed vs Velocity

Front

What is the definition of speed?

Back

Speed is the distance traveled per unit of time, regardless of direction.

Front

What is the definition of velocity?

Back

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

Front

What is the unit of speed?

Back

Common units of speed include meters per second (m/s), kilometers per hour (km/h), and miles per hour (mi/hr).

Front

What is the difference between speed and velocity?

Back

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

Front

If a car travels 60 km in 1 hour, what is its speed?

Back

Speed = Distance/Time = 60 km/1 hr = 60 km/hr.

Front

If a person walks 3 km east in 30 minutes, what is their velocity?

Back

Velocity = Displacement/Time = 3 km east/0.5 hr = 6 km/hr east.

Front

What does it mean if an object has a constant speed?

Back

It means the object covers equal distances in equal intervals of time without changing its speed.

Front

What does it mean if an object has a constant velocity?

Back

It means the object moves in a straight line at a constant speed without changing direction.

Front

What is acceleration?

Back

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

Front

How can velocity change if speed remains constant?

Back

Velocity can change if the direction of motion changes, even if the speed remains constant.
