What is speed?

Back

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

Front

How do you calculate speed?

Back

Speed = Distance / Time.

Front

What is motion?

Back

Motion is a change in position of an object compared to a starting location over time.

Front

If a runner travels 15 meters in 5 seconds, what is their speed?

Back

3 m/s.

Front

What is the formula for calculating distance?

Back

Distance = Speed x Time.

Front

If an object travels 10 meters in 20 seconds, what is its speed?

Back

0.5 m/s.

Front

What does a speed of 0 m/s indicate?

Back

It indicates that the object is at rest and not moving.

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity of an object over time.

Front

If a car increases its speed from 20 m/s to 30 m/s in 5 seconds, what is its acceleration?

Back

2 m/s².

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).
