Force and Motion 2 (Speed/Distance/Time)

Front

What is the formula to calculate speed?

Back

Speed = Distance ÷ Time

Front

What two measurements are necessary to determine the speed of an object?

Back

The distance moved by the object and the time it took to move.

Front

If a train travels 210 miles at a constant speed of 70 mph, how long will it take to reach its first stop?

Back

3 hours.

Front

How do you calculate the speed of an object given the distance and time?

Back

Speed is calculated by dividing the distance traveled by the time taken.

Front

What is the speed of a runner who runs 400 meters in 40 seconds?

Back

10 meters/second.

Front

In a speed vs. time graph, what does a steep slope indicate?

Back

A steep slope indicates a high speed or acceleration.

Front

What does it mean if a runner's speed decreases over a race?

Back

It means the runner is slowing down.

Front

How can you determine when an object's speed increased the most on a graph?

Back

Look for the steepest slope on the graph.

Front

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

Back

Speed is directly proportional to distance and inversely proportional to time.

Front

What is constant speed?

Back

Constant speed means an object covers equal distances in equal intervals of time.
