Calculation Practice

Front

What is the formula for calculating speed?

Back

Speed = Distance divided by Time.

Front

What two measurements are necessary for calculating speed?

Back

Distance and Time.

Front

If an object travels 20 meters in 4 seconds, what is its speed?

Back

5 m/s.

Front

What is net force?

Back

The total force acting on an object, taking into account both magnitude and direction.

Front

How do you calculate net force when multiple forces are acting on an object?

Back

Add the forces in the same direction and subtract the forces in the opposite direction.

Front

What is the unit of speed in the metric system?

Back

Meters per second (m/s).

Front

If a car travels 100 meters in 5 seconds, what is its speed?

Back

20 m/s.

Front

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

Back

Distance = Speed x Time.

Front

How far does a person travel if they walk at a speed of 3 m/s for 10 seconds?

Back

30 meters.

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).
