Newton Laws of Motion Flashcard Review

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 another name for Newton’s First Law?

Back

Law of Inertia.

Front

What does Newton's Second 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

If the mass of an object increases while the force remains constant, what happens to its acceleration?

Back

Acceleration decreases.

Front

What is Newton's Third Law of Motion?

Back

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

Front

What is the formula to calculate force?

Back

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

Front

If a force of 90N is applied to two carts with different masses, which cart will accelerate faster?

Back

The cart with the smaller mass will accelerate faster.

Front

What is the unit of force in the International System of Units (SI)?

Back

Newton (N).

Front

How do you calculate acceleration?

Back

Acceleration (a) = net force (F) / mass (m).

Front

What is inertia?

Back

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