Speed, Velocity, Acceleration V2

Front

What is speed?

Back

Speed is the distance traveled per unit of time, typically measured in km/hr.

Front

What is velocity?

Back

Velocity is the speed of an object in a specific direction, e.g., 15 km/hr north.

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity per unit of time, measured in km/hr².

Front

How do you calculate average speed?

Back

Average speed = Total distance / Total time.

Front

If a cyclist travels 30 km north in 2 hours, what is their velocity?

Back

15 km/hr north.

Front

A car accelerates from 0 to 60 km/hr in 10 seconds. What is the car's acceleration?

Back

0.6 km/hr².

Front

A cyclist covers 50 km in 2.5 hours. What is their average speed?

Back

20 km/hr.

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 is the formula for calculating acceleration?

Back

Acceleration = (Final velocity - Initial velocity) / Time.

Front

If a train travels 90 km in an hour, what is its speed?

Back

90 km/hr.
