Speed, Velocity and Acceleration

Front

What is speed?

Back

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

Front

How do you calculate average speed?

Back

Average speed is calculated by dividing the total distance traveled by the total time taken.

Front

If a car travels 150 km in 3 hours, what is its average speed?

Back

50 km/h

Front

What is the definition of velocity?

Back

Velocity is the speed of an object in a particular direction.

Front

How is velocity different from speed?

Back

Speed is a scalar quantity (only magnitude), while velocity is a vector quantity (magnitude and direction).

Front

What is acceleration?

Back

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

Front

If a bicyclist increases her speed from 10 km/h to 20 km/h in 5 seconds, what is her acceleration?

Back

2 km/h²

Front

What is the formula for calculating acceleration?

Back

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

Front

What is uniform motion?

Back

Uniform motion occurs when an object travels equal distances in equal intervals of time.

Front

What is the formula for average speed?

Back

Average Speed = Total Distance / Total Time.
