What indicates that an object is in motion?

Back

A change in position relative to a reference point.

Front

How can you compare the speeds of two objects?

Back

By calculating the distance each object travels in the same amount of time.

Front

What is a free body diagram?

Back

A graphical representation that shows all the forces acting on an object.

Front

What is the significance of the slope on a distance-time graph?

Back

The slope represents the speed of the object.

Front

How do balanced forces affect an object's motion?

Back

Balanced forces do not change the motion of an object; it remains at rest or continues moving at a constant speed.
