Newton's 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 with the same speed and in the same direction 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 affect inertia?

Back

The greater the mass of an object, the greater its inertia.

Front

What is the unit of measurement for force?

Back

Newtons (N).

Front

What is the relationship between mass and inertia?

Back

An object's inertia is directly proportional to its mass.

Front

What does it mean when we say an object is in motion?

Back

An object is in motion if it changes its position relative to a reference point.

Front

What is an example of an object with high inertia?

Back

An 18-wheeler truck has high inertia due to its large mass.

Front

What is an example of an object with low inertia?

Back

A small bicycle has low inertia due to its small mass.

Front

What happens to a moving object if no external force acts on it?

Back

It will continue 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.
