Newtons first law of motion

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 inertia?

Back

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

Front

How does mass relate to inertia?

Back

Objects with greater mass have greater inertia.

Front

What kind of objects have inertia?

Back

All objects with mass have inertia.

Front

What happens to an object in motion when no unbalanced force acts on it?

Back

It continues to move at a constant velocity.

Front

What is an unbalanced force?

Back

An unbalanced force is a force that causes an object to change its state of motion.

Front

What is the law of inertia?

Back

The law of inertia states that an object will maintain its state of rest or uniform motion unless acted upon by an external force.

Front

Can an object at rest have inertia?

Back

Yes, an object at rest has inertia; it resists changes to its state of rest.

Front

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

Back

Force is required to change the motion of an object.

Front

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

Back

A book on a table remains at rest until someone pushes it.
