Speed and Velocity

Front

What is speed?

Back

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

Front

What is velocity?

Back

Velocity is the speed of an object in a specific direction, expressed in units like meters per second (m/s) with a directional component (e.g., 12 m/s North).

Front

What is the difference between speed and velocity?

Back

Speed is a scalar quantity that only measures how fast an object is moving, while velocity is a vector quantity that includes both speed and direction.

Front

What does it mean for an object to be in motion?

Back

An object is in motion if its position changes relative to another object over time.

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity of an object, typically measured in meters per second squared (m/s²).

Front

How do you calculate average speed?

Back

Average speed is calculated by dividing the total distance traveled by the total time taken (Average Speed = Total Distance / Total Time).

Front

What is a frame of reference?

Back

A frame of reference is a set of coordinates or a background against which motion is measured, often involving a stationary object.

Front

What is an example of velocity?

Back

An example of velocity is 65 miles per hour South, which includes both speed and direction.

Front

What is a scalar quantity?

Back

A scalar quantity is a physical quantity that has only magnitude and no direction, such as speed or mass.

Front

What is a vector quantity?

Back

A vector quantity is a physical quantity that has both magnitude and direction, such as velocity or force.
