12/2 Speed and Graphs

Front

What is speed?

Back

The distance an object travels per unit of time.

Front

How do you calculate average speed?

Back

Average speed is calculated by dividing the total distance traveled by the total time taken.

Front

What is the formula for speed?

Back

Speed = distance/time (distance divided by time).

Front

What tools can be used to measure speed?

Back

A stopwatch and a meter stick.

Front

If an object travels 42 meters in 6 seconds, what is its average speed?

Back

7 m/s.

Front

What is the speed of an object that travels 40 meters in 4 minutes?

Back

10 m/min.

Front

What is the difference between speed and velocity?

Back

Speed is a scalar quantity (only magnitude), 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 kilometers per hour (km/h).

Front

What is displacement?

Back

Displacement is the shortest distance from the initial to the final position of an object, including direction.

Front

What is acceleration?

Back

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