Motion: 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, combining both magnitude and direction.

Front

What is acceleration?

Back

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

Front

What does a distance vs. time graph show?

Back

A distance vs. time graph shows how the distance traveled by an object changes over time, helping to visualize speed.

Front

What does a constant speed look like on a graph?

Back

A constant speed is represented by a straight line on a distance vs. time graph.

Front

What does a decreasing speed look like on a graph?

Back

A decreasing speed is represented by a curve that slopes downward on a distance vs. time graph.

Front

What is the formula for calculating speed?

Back

Speed = Distance / Time.

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 is positive acceleration?

Back

Positive acceleration occurs when an object's velocity increases over time.

Front

What is negative acceleration (deceleration)?

Back

Negative acceleration occurs when an object's velocity decreases over time.
