Front

What is the formula for calculating speed?

Back

Speed = Distance / Time

Front

What unit is commonly used to measure speed?

Back

km/hr

Front

How does velocity differ from speed?

Back

Velocity has a direction associated with it, while speed has no specific direction.

Front

What term describes the rate of change of velocity?

Back

Acceleration

Front

What is another term for the speed and direction of an object?

Back

Velocity

Front

If an object is moving at a constant speed, what can be said about its acceleration?

Back

The acceleration is zero.

Front

What happens to the speed of an object when it accelerates?

Back

The speed increases.

Front

What is the relationship between distance, speed, and time?

Back

Distance = Speed x Time

Front

What is the unit of acceleration in the metric system?

Back

m/s² (meters per second squared)
