Speed/Velocity/Acceleration

Front

What is speed?

Back

Speed is how much distance is covered over a period of time.

Front

What is velocity?

Back

Velocity is speed in a specific direction.

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity over time.

Front

What is the difference between speed and velocity?

Back

Speed is a scalar quantity that refers to how fast an object is moving, while velocity is a vector quantity that includes both speed and direction.

Front

What are the units of speed?

Back

Common units of speed include meters per second (m/s) and kilometers per hour (km/h).

Front

What are the units of acceleration?

Back

Common units of acceleration include meters per second squared (m/s²).

Front

If a car travels 100 meters in 5 seconds, what is its speed?

Back

The speed is 20 meters per second (100 meters / 5 seconds).

Front

What does it mean if an object has a constant velocity?

Back

It means the object is moving at a constant speed in a straight line without changing direction.

Front

What is an example of negative acceleration?

Back

An example of negative acceleration is when a car slows down as it approaches a stop sign.

Front

How does changing direction affect velocity?

Back

Changing direction affects velocity because velocity is a vector quantity that depends on both speed and direction.
