Review: Newton's Laws

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 unless acted upon by a net external force.

Front

What is inertia?

Back

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

Front

What is the formula for Newton's Second Law of Motion?

Back

F = mass * acceleration.

Front

How do you calculate force using mass and acceleration?

Back

Multiply the mass of the object by its acceleration.

Front

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

Back

Newton (N).

Front

If a 2 kg object is accelerated at 6 m/s², what is the force applied?

Back

12 N.

Front

What does Newton's Third Law of Motion state?

Back

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

Front

What is an example of Newton's Third Law?

Back

When you push against a wall, the wall pushes back with equal force.

Front

What happens to a moving object when no net force acts on it?

Back

It continues to move at a constant velocity.

Front

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

Back

As mass increases, acceleration decreases for a constant force.
