Vocab Flashcard #8

Front

What is 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

What is an unbalanced force?

Back

A force that causes an object to change its state of motion, such as a ball rolling down a hill.

Front

What does Newton's 2nd Law state about force, mass, and acceleration?

Back

Force equals mass times acceleration (F = ma).

Front

How do you calculate net force if a car has a mass of 1000 kg and accelerates at 2 m/s²?

Back

Net force = mass × acceleration = 1000 kg × 2 m/s² = 2000 N.

Front

What does accountability mean?

Back

Taking ownership of your actions and responsibilities.

Front

What is inertia?

Back

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

Front

What is the formula for calculating force?

Back

Force (F) = mass (m) × acceleration (a).

Front

What is an example of balanced forces?

Back

A car parked on a flat road, where all forces acting on it are equal.

Front

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

Back

As mass increases, for a constant force, acceleration decreases.

Front

What is the unit of force in the SI system?

Back

The unit of force is the Newton (N).
