Speed Velocity and Acceleration

Front

What is speed?

Back

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

Front

What is velocity?

Back

Velocity is the speed of an object in a specific direction. It is a vector quantity.

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity per unit of time. It can be positive (speeding up) or negative (slowing down).

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 does a constant speed graph look like?

Back

A constant speed graph is a straight line on a distance-time graph.

Front

What does an acceleration graph look like?

Back

An acceleration graph shows a curve that indicates increasing speed over time.

Front

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

Back

A flat line indicates that the object is not moving.

Front

What are the units of acceleration?

Back

The units of acceleration are meters per second squared (m/s²).

Front

How does time affect speed?

Back

Speed increases if the distance traveled increases while time remains constant.
