Warm-up-Newton's First Law

Front

What is inertia?

Back

Inertia is the tendency of an object to resist a change in its state of motion, whether it is at rest or moving.

Front

Which objects have inertia?

Back

All objects with mass have inertia.

Front

What does Newton's First Law state?

Back

Newton's First Law states that an object at rest will remain at rest, and an object in motion will continue in motion at a constant velocity unless acted upon by an unbalanced force.

Front

How does inertia affect a resting object?

Back

A resting object will remain at rest due to inertia.

Front

How does inertia affect a moving object?

Back

A moving object will keep moving at a constant velocity unless acted on by an unbalanced force due to inertia.

Front

What is an unbalanced force?

Back

An unbalanced force is a force that causes a change in the motion of an object, resulting in acceleration or deceleration.

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 the relationship between mass and inertia?

Back

The greater the mass of an object, the greater its inertia, meaning it will resist changes in its motion more than an object with less mass.

Front

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

Back

If no unbalanced force acts on it, the object will continue to move in a straight line at a constant speed.

Front

What is an example of inertia in everyday life?

Back

An example of inertia is when a passenger in a car lurches forward when the car suddenly stops; the passenger's body wants to continue moving forward.
