Front

What is speed?

Back

Speed is the distance traveled per unit of time, typically measured in meters per second (m/s) or miles per hour (mi/hr).

Front

What is velocity?

Back

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

Front

What is the formula for calculating speed?

Back

Speed = Distance / Time.

Front

If a car travels 100 miles in 2 hours, what is its speed?

Back

50 mi/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 unit is commonly used to measure speed?

Back

Meters per second (m/s) or miles per hour (mi/hr).

Front

What is average speed?

Back

Average speed is the total distance traveled divided by the total time taken.

Front

If a runner completes a 400 meter lap in 50 seconds, what is their average speed?

Back

8 m/s.

Front

What does it mean if an object has a constant velocity?

Back

It means the object is moving at the same speed and in the same direction.

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity over time.
