Speed and Motion

Front

What is speed?

Back

Speed is how much distance is covered over a period of time.

Front

What is velocity?

Back

Velocity describes an object's speed in a given direction.

Front

What does it mean if an object is not moving?

Back

It means the object is stopped, stationary, or at rest.

Front

Which of the following is an example of velocity? 34 m/s south or 26 m/s?

Back

34 m/s south is an example of velocity.

Front

What two measurements are necessary for calculating speed?

Back

Distance and time are necessary for calculating speed.

Front

What is the formula for calculating speed?

Back

Speed = Distance / Time.

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity of an object.

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 a reference point in motion?

Back

A reference point is a stationary object used to determine the position of a moving object.

Front

What is constant speed?

Back

Constant speed means an object covers equal distances in equal intervals of time.
