Calculating Speed, Velocity, and Acceleration

Front

What is speed?

Back

Speed is the distance traveled per unit of time, typically measured in kilometers per hour (km/h) or miles per hour (mph).

Front

What is the formula for calculating speed?

Back

Speed = Distance / Time

Front

What is velocity?

Back

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

Front

How is acceleration defined?

Back

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

Front

What is the formula for calculating acceleration?

Back

Acceleration = (Final Velocity - Initial Velocity) / 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

If a cyclist travels 40 km in 2 hours, what is their average speed?

Back

20 km/h

Front

What does a horizontal line on a distance-time graph represent?

Back

No motion (the object is stationary).

Front

If a car travels at a constant speed of 60 mph for 3 hours, how far does it travel?

Back

180 miles

Front

What is the unit of acceleration?

Back

Meters per second squared (m/s²).
