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. It includes both the magnitude (speed) and the direction of motion.

Front

What is acceleration?

Back

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

Front

What does a flat line on a distance vs. time graph indicate?

Back

A flat line indicates that the object is not moving.

Front

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

Back

A straight diagonal line represents constant speed.

Front

What does a curved line on a distance vs. time graph indicate?

Back

A curved line indicates that the object is accelerating or decelerating.

Front

How do you calculate speed?

Back

Speed = Distance / Time.

Front

What is the difference between speed and velocity?

Back

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

Front

What is deceleration?

Back

Deceleration is a decrease in speed or negative acceleration.

Front

What is the unit of acceleration?

Back

The unit of acceleration is meters per second squared (m/s²).
