Newton's 3 Laws Flashcard

Front

What is Newton's First Law of Motion?

Back

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

Front

What is Newton's Second Law of Motion?

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 Newton's Third Law of Motion?

Back

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

Front

What is the formula for calculating speed?

Back

Speed = Distance / Time.

Front

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

Back

Newton (N).

Front

What is velocity?

Back

Velocity is speed in a specific direction.

Front

What is inertia?

Back

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

Front

What is momentum?

Back

Momentum is the product of an object's mass and its velocity (p = mv).

Front

How does mass affect acceleration according to Newton's Second Law?

Back

As mass increases, acceleration decreases if the same force is applied.

Front

What happens to the motion of a boat when a person steps off it?

Back

The boat moves backward due to the action-reaction principle (Newton's Third Law).
