Newton's Laws of Motion Flashcard

Front

What happens to the acceleration of an object if its mass is tripled while the force remains constant?

Back

The acceleration is reduced to one-third.

Front

What is Newton's First Law of Motion?

Back

An object at rest stays at rest, and an object in motion continues in motion with the same speed and in the same direction unless acted upon by a net external force.

Front

Provide an example of Newton's First Law of Motion.

Back

A ball thrown in space continues moving indefinitely.

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 (F=ma).

Front

What is Newton's Third Law of Motion?

Back

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

Provide an example of Newton's Third Law of Motion.

Back

A person pushing against a wall and the wall pushing back.

Front

Which law explains why passengers lurch forward when a car suddenly stops?

Back

Newton's First Law.

Front

What is inertia in the context of Newton's First Law?

Back

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

Front

What is the relationship between force, mass, and acceleration according to Newton's Second Law?

Back

Force equals mass times acceleration (F=ma).

Front

What is an example of a scenario that illustrates Newton's Second Law?

Back

A heavier object requires more force to accelerate than a lighter object.
