Speed, Velocity, and Acceleration

Front

What is speed?

Back

Speed is the distance traveled per unit of time, typically measured in miles per hour (mph) or meters per second (m/s).

Front

What is velocity?

Back

Velocity is the speed of an object in a specific direction, such as 60 mph north.

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity over time, indicating how quickly an object is speeding up or slowing down.

Front

What is the formula for calculating speed?

Back

Speed = Distance / Time.

Front

What does a constant speed look like on a distance vs. time graph?

Back

A straight diagonal line indicates constant speed.

Front

What does it mean if an object is accelerating?

Back

It means the object's velocity is changing, either increasing or decreasing.

Front

How can you tell if an object is slowing down on a graph?

Back

The slope of the distance vs. time graph becomes less steep.

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

What does a horizontal line on a distance vs. time graph represent?

Back

It represents an object that is not moving (speed = 0).

Front

What is an example of negative acceleration?

Back

A car slowing down from 30 mph to a stop.
