Inertia: Newtons first Law

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 with the same speed and in the same direction unless acted upon by an unbalanced force.

Front

What is inertia?

Back

Inertia is an object's tendency to stay in its state of motion, whether at rest or moving.

Front

Does inertia apply to moving objects, nonmoving objects, or both?

Back

Inertia applies to both moving and nonmoving objects.

Front

What is friction?

Back

Friction is a force that opposes motion between any surfaces that are touching.

Front

What kind of objects have inertia?

Back

All objects with mass have inertia.

Front

What happens to passengers in a car that crashes into a wall?

Back

They will keep moving forward until they hit their seatbelt or the dashboard.

Front

How does mass affect inertia?

Back

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

Front

What is an example of inertia in everyday life?

Back

A book resting on a table will remain at rest until someone picks it up.

Front

What is the relationship between force and motion according to Newton's First Law?

Back

An unbalanced force is required to change the motion of an object.

Front

What is an unbalanced force?

Back

An unbalanced force is a force that causes an object to accelerate, decelerate, or change direction.
