Speed and Velocity

Front

What is speed?

Back

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

Front

What is velocity?

Back

Velocity is the speed of an object in a specific direction, combining 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 train travels 300 km north in 3 hours, what is its velocity?

Back

Velocity = 300 km north / 3 hr = 100 km/hr north.

Front

What units are commonly used to measure speed?

Back

Common units include kilometers per hour (km/hr) and meters per second (m/s).

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, regardless of the 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, including direction.
