Newton's 1st Law Practice #1

Front

What is inertia?

Back

Inertia is the tendency of an object to resist changes in its state of motion. It means that an object at rest stays at rest, and an object in motion stays in motion unless acted upon by an external force.

Front

What does Newton's First Law of Motion state?

Back

Newton's First Law of Motion states that an object at rest stays at rest, and an object in motion stays in motion unless acted upon by another force.

Front

What kind of objects have inertia?

Back

All objects with mass have inertia.

Front

What is an example of Newton's First Law in everyday life?

Back

A pencil resting on a desk will remain at rest until someone picks it up.

Front

How does Newton's First Law apply to moving objects?

Back

Newton's First Law applies to moving objects by stating that they will continue moving in a straight line at constant speed unless acted upon by an external force.

Front

What is the relationship between mass and inertia?

Back

The greater the mass of an object, the greater its inertia, meaning it will be harder to change its state of motion.

Front

What happens to a rock sitting on the ground in terms of forces?

Back

A rock sitting on the ground experiences balanced forces, meaning the force of gravity pulling it down is equal to the normal force pushing it up.

Front

What is an unbalanced force?

Back

An unbalanced force is a force that causes an object to change its state of motion, either by starting to move, stopping, or changing direction.

Front

Can Newton's First Law apply to nonmoving objects?

Back

Yes, Newton's First Law applies to both moving and nonmoving objects.

Front

What is an example of an unbalanced force?

Back

Pushing a stationary car to get it moving is an example of an unbalanced force.
