Newton's 3 Laws Flashcard

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 the formula to calculate force?

Back

Force (F) = mass (m) × acceleration (a) or F = m × a.

Front

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

Back

The unit of force is the Newton (N).

Front

What does Newton's Second Law of Motion state?

Back

The acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass.

Front

What is Newton's Third Law of Motion?

Back

For every action, there is an equal and opposite reaction.

Front

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

Back

As mass increases, acceleration decreases for a given force.

Front

What is inertia?

Back

Inertia is the tendency of an object to resist changes in its state of motion.

Front

Provide an example of Newton's First Law in everyday life.

Back

A book resting on a table will remain at rest until someone pushes it.

Front

What happens to the forces acting on an object in equilibrium?

Back

The net force acting on the object is zero.

Front

Explain the concept of action-reaction pairs in Newton's Third Law.

Back

When one object exerts a force on a second object, the second object exerts an equal and opposite force on the first object.
