10-28 Calculating Speed & Motion Graphs

Front

What is the formula to calculate distance when speed and time are known?

Back

Distance = Speed × Time

Front

If a car travels at a speed of 60 miles per hour for 3 hours, how far does it travel?

Back

180 miles

Front

What is velocity?

Back

Velocity is speed in a given direction.

Front

What does a horizontal line on a motion graph represent?

Back

A body at rest.

Front

How do you calculate speed?

Back

Speed = Distance ÷ Time

Front

If an object accelerates, what does that mean?

Back

It means the object's speed is changing.

Front

What does a steep slope on a motion graph indicate?

Back

A high speed.

Front

If Skyler walks at a speed of 0.5 meters/second, how long will it take her to walk 20 meters?

Back

40 seconds

Front

What does a downward slope on a motion graph represent?

Back

Slowing down.

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).
