P.5E - Newton's 1st Law of Motion Review

Front

What is Newton's 1st Law of Motion?

Back

An object at rest stays at rest, and an object in motion stays in motion at a constant velocity unless acted upon by a net external force.

Front

What is inertia?

Back

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 happens to a passenger in a car that suddenly stops?

Back

The passenger continues moving forward due to inertia.

Front

What is an example of Newton's 1st Law in everyday life?

Back

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

Front

What does it mean for an object to be in motion?

Back

It means the object is changing its position relative to a reference point.

Front

What is a net external force?

Back

The overall force acting on an object when all individual forces are combined.

Front

If a ball is rolling on a flat surface, what will happen if no external forces act on it?

Back

It will continue to roll at a constant speed in a straight line.

Front

What is the relationship between force and motion according to Newton's 1st Law?

Back

Force is required to change the motion of an object.

Front

What is an example of inertia in sports?

Back

A soccer ball will not move until kicked.
