Newtons Laws of Motion Flashcard

Front

What is the definition of force?

Back

A force is a push or pull on an object that can cause it to move, stop, or change direction.

Front

What does Newton's First Law of Motion state?

Back

An object at rest stays at rest, and an object in motion stays in motion at a constant velocity 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 (F=ma).

Front

What is Newton's Third Law of Motion?

Back

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

Front

What is an example of Newton's First Law of Motion?

Back

A soccer ball remains at rest until a player kicks it.

Front

What is an example of Newton's Second Law of Motion?

Back

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

Front

What is an example of Newton's Third Law of Motion?

Back

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

Front

What is inertia?

Back

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

Front

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

Back

As mass increases, acceleration decreases for a given force.

Front

What is the formula for calculating force?

Back

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