Newton's First and Third Law 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 Newton's Third Law of Motion?

Back

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

Front

What does it mean for an object to be stationary?

Back

It means the object is not in motion.

Front

If a bug splatters against a moving car, how do the forces compare?

Back

The force of the car on the bug is the same as the force of the bug on the car.

Front

What is the reaction force when a dog touches a ball?

Back

The ball touching the dog.

Front

In a tug-of-war, if both sides pull with equal force, what is the tension in the rope?

Back

The tension in the rope is equal to the force exerted by each side.

Front

What happens when you push gently on an object according to Newton's Third Law?

Back

The object pushes gently back on you.

Front

What is an unbalanced force?

Back

A force that causes an object to accelerate, changing its state of motion.

Front

What is inertia?

Back

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

Front

How does air resistance affect a falling object?

Back

Air resistance opposes the motion of the object, affecting its acceleration and speed.
