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. (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 net force?

Back

The combination of all the forces acting on an object.

Front

What is air resistance?

Back

A force that opposes the motion of an object through the air.

Front

What is inertia?

Back

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

Front

What is an unbalanced force?

Back

A force that causes an object to accelerate, resulting in a change in motion.

Front

What is gravity?

Back

A force that attracts two bodies toward each other, commonly experienced as the force that pulls objects toward the Earth.

Front

What is an example of Newton's 1st Law in everyday life?

Back

A passenger in a car continues to move forward when the car suddenly stops.

Front

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

Back

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