Newton's Laws Flashcard

Front

What is the rate of change of velocity called?

Back

Acceleration is the rate of change of velocity of an object.

Front

According to Newton's first law of motion, an object at rest will remain at rest unless acted upon by what?

Back

An external force is required to change the state of motion of an object.

Front

What is the formula to calculate acceleration?

Back

Acceleration (a) = Force (F) / Mass (m) or a = F/m.

Front

What is the acceleration of an object with a mass of 5 kg and a force of 20 N?

Back

The acceleration is 4 m/s².

Front

Which law of motion states that an object in motion will stay in motion with the same speed and direction unless acted upon by an external force?

Back

Newton's First Law of Motion.

Front

According to Newton's third law of motion, for every action, there is an equal and opposite what?

Back

Reaction.

Front

What is inertia?

Back

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

Front

What does Newton's Second Law of Motion state?

Back

It states that the acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass.

Front

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

Back

The unit of force is the Newton (N).

Front

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

Back

As mass increases, acceleration decreases for a given force.
