What law is best described by inertia?

• 1st
• 2nd
• 3rd

A person’s body is thrown outward as a car rounds a curve on a highway.

• Newton's 1st Law
• Newton's 2nd Law
• Newton's 3rd Law
• None of them

Rockets are launched into space using jet propulsion where exhaust accelerates out from the rocket and the rocket accelerates in an opposite direction.

• Newton's 1st Law
• Newton's 2nd Law
• Newton's 3rd Law
• None of them

Acceleration is produced when a force acts on a mass. The greater the mass (of the object being accelerated) the greater the amount of force needed (to accelerate the object).

• Newton's 1st Law
• Newton's 2nd Law
• Newton's 3rd Law
• None of them

"An object in motion (or at rest) will to stay in motion (or at rest) until an outside force acts upon it."

• Newton's 1st Law
• Newton's 2nd Law
• Newton's 3rd Law
• Newton's 4th Law
