Motion (7th Grade Science)

Front

What is motion?

Back

Motion is the change in position of an object over time.

Front

What is average speed?

Back

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

Front

How do you calculate average speed?

Back

Average speed = Total distance / Total time.

Front

What is velocity?

Back

Velocity is the speed of an object in a specific 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 at rest?

Back

An object is at rest if its position does not change over time.

Front

What is acceleration?

Back

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

Front

What is the formula for acceleration?

Back

Acceleration = (Final velocity - Initial velocity) / Time.

Front

What is a reference point?

Back

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

Front

What is the unit of speed?

Back

The unit of speed is typically meters per second (m/s) or kilometers per hour (km/h).
