7.7D Flashcard

Front

An object in motion stops when.....

Back

it is acted upon by an outside force.

Front

An object in motion tends to stay in motion unless an ___ force acts on it.

Back

unbalanced

Front

What is inertia?

Back

An object's tendency to stay in motion or to stay at rest.

Front

If an object is not moving, the forces acting upon it are _____________

Back

balanced

Front

_____ forces are those acting on an object that combine and form a net force that is not zero, therefore the object's motion changes.

Back

unbalanced

Front

What is the definition of balanced forces?

Back

Forces that are equal in size and opposite in direction, resulting in no change in motion.

Front

What happens to an object when a net force is applied?

Back

The object will accelerate in the direction of the net force.

Front

What is Newton's First Law of Motion?

Back

An object at rest stays at rest, and an object in motion stays in motion unless acted upon by an unbalanced force.

Front

What is an example of inertia in everyday life?

Back

A passenger lurching forward in a car when it suddenly stops.

Front

What is the difference between balanced and unbalanced forces?

Back

Balanced forces do not change an object's motion, while unbalanced forces do.
