Newton's 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 a net external force.

Front

What is Newton's Second Law of Motion?

Back

The acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass. It is often expressed as the equation ΣF=ma.

Front

What is Newton's Third Law of Motion?

Back

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

Front

What is the SI unit for force?

Back

The SI unit for force is the Newton (N).

Front

What is the SI unit for mass?

Back

The SI unit for mass is the kilogram (kg).

Front

What does the term 'inertia' refer to?

Back

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

Front

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

Back

As mass increases, for a given force, the acceleration decreases.

Front

What is the relationship between force, mass, and acceleration?

Back

The relationship is defined by the equation F = ma, where F is force, m is mass, and a is acceleration.

Front

What is 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

How can you demonstrate Newton's Third Law?

Back

When you jump off a small boat, you push the boat backward as you move forward.
