Newton's 1st Law

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 with the same speed and in the same direction unless acted upon by a net external force.

Front

What is inertia?

Back

Inertia is the tendency of an object to resist changes in its state of motion. It is directly related to the mass of the object.

Front

If an object has a larger mass, what can be said about its inertia?

Back

The object with a larger mass has greater inertia.

Front

What kind of objects have inertia?

Back

All objects with mass have inertia.

Front

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

Back

It continues to move at a constant velocity.

Front

What is a net force?

Back

The net force is the vector sum of all the forces acting on an object.

Front

If two forces of equal magnitude act in opposite directions on an object, what is the net force?

Back

The net force is zero.

Front

What is the unit of force in the International System of Units (SI)?

Back

The unit of force is the Newton (N).

Front

How does mass affect acceleration according to Newton's 2nd Law?

Back

According to Newton's 2nd Law, acceleration is inversely proportional to mass when the net force is constant.

Front

What is the relationship between mass and weight?

Back

Weight is the force of gravity acting on an object, calculated as mass times the acceleration due to gravity (W = m * g).
