Newton's 3 Laws Flashcard

Front

What is Newton's 1st Law of Motion?

Back

An object at rest will stay at rest and an object in motion will stay in motion unless acted upon by a net external force.

Front

What is the law of inertia?

Back

It is another name for Newton's 1st Law of Motion, which states that objects resist changes in their state of motion.

Front

What does Newton's 2nd Law of Motion state?

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 the formula to calculate force?

Back

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

Front

What is Newton's 3rd Law of Motion?

Back

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

Front

What happens when a magician pulls a tablecloth from under dishes?

Back

It demonstrates Newton's 1st Law; the dishes remain at rest due to inertia.

Front

If a 10 kg object accelerates at 15 m/s², what is the force applied?

Back

150 Newtons (using F = ma).

Front

What is the relationship between mass and acceleration in Newton's 2nd Law?

Back

As mass increases, acceleration decreases if the force remains constant.

Front

What is an example of Newton's 3rd Law in everyday life?

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.
