8.6C Newton's Laws Review

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 with the same speed and in the same direction unless acted upon by an unbalanced force.

Front

What is Newton's 2nd Law of Motion?

Back

The acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass. This is often expressed as F=ma.

Front

What is Newton's 3rd Law of Motion?

Back

For every action, there is an equal and opposite reaction.

Front

What is a force?

Back

A push or pull on an object.

Front

What is inertia?

Back

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

Front

What is mass?

Back

The amount of matter in an object, typically measured in kilograms.

Front

What is acceleration?

Back

The rate of change of velocity of an object, typically measured in meters per second squared (m/s²).

Front

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

Back

As mass increases, acceleration decreases if the net force remains constant.

Front

What is an unbalanced force?

Back

A force that causes an object to accelerate, as it is not equal and opposite to other forces acting on the object.

Front

What is jet propulsion?

Back

A method of propulsion that uses the expulsion of gas to create thrust, as seen in rockets.
