SSA Review (Motion of Objects: Big Idea 12)

Front

What is speed?

Back

Speed is the distance traveled per unit of time. It is a scalar quantity and does not have a direction.

Front

What is acceleration?

Back

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

Front

What does a horizontal line on a distance-time graph represent?

Back

A horizontal line indicates that the object is not moving; it is stationary.

Front

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

Back

A straight diagonal line indicates constant speed; the object is moving at a steady pace.

Front

What does a curved line on a distance-time graph represent?

Back

A curved line indicates acceleration; the object is speeding up or slowing down.

Front

What is the formula for calculating speed?

Back

Speed = Distance / Time.

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 a negative slope on a distance-time graph indicate?

Back

A negative slope indicates that the object is moving back towards the starting point.

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).

Front

What does it mean if an object has a constant speed?

Back

It means the object covers equal distances in equal intervals of time.
