Front

What does Newton’s First Law of Motion state?

Back

An object at rest/in motion will remain at rest/in motion unless acted upon by an unbalanced force.

Front

What is another name for Newton's First Law?

Back

Law of Inertia

Front

What is Newton's Second Law of Motion?

Back

F = m * a (Force equals mass times acceleration)

Front

If a horse is pulling with a force of 130 N and is moving at 0.8 m/s, what is the mass of the horse?

Back

162.5 kg

Front

What is one newton equivalent to?

Back

1 kg•m/sec²

Front

What is the relationship between force, mass, and acceleration?

Back

Force is equal to mass multiplied by acceleration (F = m * a).

Front

What is inertia?

Back

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

Front

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

Back

Newton (N)

Front

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

Back

As mass increases, acceleration decreases for a given force.

Front

What is the formula to calculate force?

Back

F = m * a
