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. It is a vector quantity, meaning it has both magnitude and direction.

Front

How do you calculate 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 150 km in 3 hours, what is its speed?

Back

Speed = 150 km / 3 hr = 50 km/hr.

Front

What is the formula for calculating velocity?

Back

Velocity = Displacement / 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 lap in 50 seconds, what is their speed?

Back

Speed = 400 m / 50 s = 8 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

What is acceleration?

Back

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