Newton's Laws Review

Front

What is Newton's First Law of Motion?

Back

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

Front

What is Newton's Second Law of Motion?

Back

The acceleration of an object is directly proportional to the net force applied to it and inversely proportional to its mass.

Front

What is Newton's Third Law of Motion?

Back

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

Front

What is inertia?

Back

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

Front

What is the formula for calculating force?

Back

Force = Mass x Acceleration (F = m * a).

Front

If a 2 kg object is accelerated at 3 m/s², what is the force applied?

Back

6 N (Newtons).

Front

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

Back

Newton (N).

Front

What does it mean for an object to be in equilibrium?

Back

The net force acting on the object is zero, resulting in no acceleration.

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 the concept of action-reaction pairs?

Back

For every action force, there is a reaction force that is equal in size and opposite in direction.
