Speed vs Velocity

Front

What is the definition of Speed?

Back

Speed is the distance traveled per unit of time, typically expressed in units like km/hr or m/s.

Front

What is the definition of Velocity?

Back

Velocity is the speed of an object in a specific direction, expressed in units like m/s north.

Front

What is the formula to calculate Speed?

Back

Speed = Distance / Time.

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

What unit is commonly used to measure Speed?

Back

Common units include km/hr and m/s.

Front

What unit is commonly used to measure Velocity?

Back

Velocity is measured in units like m/s with a direction (e.g., m/s north).

Front

If a car travels 120 km in 2 hours, what is its Speed?

Back

Speed = 120 km / 2 hr = 60 km/hr.

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 is the formula to calculate Velocity?

Back

Velocity = Displacement / Time.

Front

What is Displacement?

Back

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