Speed and Velocity

Front

What is speed?

Back

Speed is the distance traveled per unit of time, typically measured in meters per second (m/s) or kilometers per hour (km/h).

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 the formula for calculating speed?

Back

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

If a car travels 100 km in 2 hours, what is its speed?

Back

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

Front

If a bird flies south at 20 m/s, what is this an example of?

Back

This is an example of velocity, as it includes both speed and direction.

Front

What do you need to calculate velocity?

Back

You need speed and direction.

Front

How do you calculate average velocity?

Back

Average Velocity = Total Displacement / Total Time.

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

If a runner completes a 400 m track in 50 seconds, what is their average speed?

Back

Average Speed = 400 m / 50 s = 8 m/s.
