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 an unbalanced force.

Front

What is inertia?

Back

Inertia is the tendency of an object to resist changes in its state of motion. The more mass an object has, the greater its inertia.

Front

How does mass affect inertia?

Back

If one object has twice as much mass as another object, it also has twice as much inertia.

Front

What happens when forces are balanced?

Back

When forces are balanced, the net force is zero, and the object remains at rest or continues to move at a constant velocity.

Front

What happens when forces are unbalanced?

Back

When forces are unbalanced, the object will accelerate in the direction of the larger force.

Front

What is net force?

Back

Net force is the vector sum of all the forces acting on an object, determining its acceleration.

Front

If an object is not moving, what can we say about the forces acting on it?

Back

If an object is not moving, the forces acting on it are balanced, resulting in a net force of zero.

Front

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

Back

A magician pulling a tablecloth out from under dishes without disturbing them is an example of Newton's 1st Law.

Front

What does it mean for forces to act in opposite directions?

Back

Forces acting in opposite directions can cancel each other out, resulting in a net force of zero.

Front

What is the significance of the direction of the net force?

Back

The direction of the net force determines the direction in which an object will accelerate.
