T3.3 Newton's Laws of Motion Flashcard CP

Front

What is Newton's First Law of Motion?

Back

An object at rest will remain at rest, and an object in motion will remain in motion at a constant velocity unless acted upon by a nonzero net 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 are action-reaction forces?

Back

Forces that occur in pairs, acting on different objects, and are equal in magnitude but opposite in direction.

Front

What happens when a dog pulls on a leash according to Newton's Third Law of Motion?

Back

The leash pulls back on the dog with equal strength in the opposite direction.

Front

What is the formula to calculate force?

Back

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

Front

What is the effect of balanced forces on an object?

Back

The object remains stationary or moves at a constant velocity.

Front

What is inertia?

Back

The tendency of an object to resist changes in its state of motion.

Front

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

Back

As mass increases, acceleration decreases for a given force.

Front

What is an example of an unbalanced force?

Back

A soccer ball being kicked, causing it to accelerate in the direction of the kick.
