Vocab Flashcard #8

Front

What happens to an object when unbalanced forces act on it?

Back

It changes its state of motion.

Front

Which of the following best describes Newton's 1st Law of Motion?

Back

An object at rest stays at rest, and an object in motion stays in motion unless acted upon by an unbalanced force.

Front

How does Newton's 2nd Law relate force, mass, and acceleration?

Back

Force equals mass times acceleration.

Front

What is the formula for calculating force?

Back

Force (F) = Mass (m) × Acceleration (a) or 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

The unit of force is the Newton (N).

Front

What does it mean for forces to be balanced?

Back

Balanced forces are equal in size and opposite in direction, resulting in no change in motion.

Front

What is the relationship between mass and acceleration in Newton's 2nd Law?

Back

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