Speed, Velocity, Acceleration

Front

What is speed?

Back

Speed refers to how fast an object is moving, measured as distance traveled per unit of time.

Front

What is velocity?

Back

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

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity of an object, which can occur when an object speeds up, slows down, or changes direction.

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 it mean if an object is accelerating?

Back

An object is accelerating if it is changing its speed or direction.

Front

Give an example of speed.

Back

A turtle is crawling at 34 cm/min.

Front

Give an example of velocity.

Back

A car driving 55 miles per hour south.

Front

What is constant speed?

Back

Constant speed means an object is moving at the same speed over time.

Front

What is average speed?

Back

Average speed is the total distance traveled divided by the total time taken.

Front

What happens to an object's velocity when it turns?

Back

The object's velocity changes because direction is a component of velocity.
