Speed vs. Velocity

Front

What is speed?

Back

Speed is the distance traveled per unit of time, regardless of direction. It is a scalar quantity.

Front

What is velocity?

Back

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

Front

If a dog runs at 9 mi/hr, what is this an example of?

Back

This is an example of speed.

Front

When a student walks 5 km/hr west, what is this an example of?

Back

This is an example of velocity.

Front

What does it mean when we say an object has a velocity of 70 mph east?

Back

It means the object is moving at 70 miles per hour in the east direction.

Front

What is the definition of displacement?

Back

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

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 100 km in 2 hours, what is its speed?

Back

Speed = Distance / Time = 100 km / 2 hr = 50 km/hr.

Front

What is the formula for calculating velocity?

Back

Velocity = Displacement / Time.

Front

If an object moves 4 m to the east, what is its displacement?

Back

The displacement is 4 m east.
