6.1 Speed and Velocity

Front

What is speed?

Back

Speed is the distance traveled per unit of time.

Front

What is the formula for calculating speed?

Back

speed = distance/time

Front

What is velocity?

Back

Velocity is speed in a specific direction.

Front

What is a unit of speed?

Back

m/s (meters per second) is a unit of speed.

Front

What is another unit of speed?

Back

km/hr (kilometers per hour) is another unit of speed.

Front

What does a distance vs. time graph represent?

Back

A distance vs. time graph shows an object's speed.

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).

Front

If an object travels 100 meters in 5 seconds, what is its speed?

Back

speed = distance/time = 100m/5s = 20 m/s.

Front

What is the significance of the slope in a distance vs. time graph?

Back

The slope represents the speed of the object.

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity over time.
