Speed, Velocity Acceleration, Graphs

Front

What is velocity?

Back

Speed in a specific direction.

Front

What is the formula for calculating speed?

Back

Speed = Distance / Time.

Front

What is acceleration?

Back

The rate of change of velocity over time.

Front

What unit is commonly used to measure speed?

Back

m/s (meters per second).

Front

If a car travels 300 meters in 15 seconds, what is its speed?

Back

20 m/s.

Front

What does a flat line on a distance-time graph indicate?

Back

The object is at rest.

Front

What does a steep slope on a distance-time graph indicate?

Back

The object is moving quickly.

Front

What is the difference between speed and velocity?

Back

Speed is scalar (magnitude only), while velocity is vector (magnitude and direction).

Front

If a runner completes a 400-meter lap in 50 seconds, what is their average speed?

Back

8 m/s.

Front

What does acceleration look like on a velocity-time graph?

Back

A straight line with a positive slope indicates constant acceleration.
