Newton's 1st Law

Front

What is a force?

Back

A force is defined as a push or a pull.

Front

What happens to an object when unbalanced forces act on it?

Back

The object will move in the direction of the larger force.

Front

Which type of forces cause a change in an object's motion?

Back

Unbalanced forces cause a change in an object's motion.

Front

To which objects does the law of inertia (Newton’s First Law) apply?

Back

The law of inertia applies to both moving and nonmoving objects.

Front

Why is the net force 0 when two forces are equal and opposite?

Back

Because they are both pulling the same amount of force in opposite directions.

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 a net external force.

Front

What is inertia?

Back

Inertia is the tendency of an object to resist changes in its state of motion.

Front

How does mass affect inertia?

Back

The greater the mass of an object, the greater its inertia.

Front

What is a balanced force?

Back

Balanced forces are equal in size and opposite in direction, resulting in no change in motion.

Front

What is an unbalanced force?

Back

Unbalanced forces are not equal and cause a change in the motion of an object.
