TEK 8.6 Newton's Laws of Motion Review

Front

What is Newton's 1st Law of Motion?

Back

An object in motion stays in motion, and an object at rest stays at rest unless acted upon by an outside 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 are balanced forces?

Back

Forces that are equal in size and opposite in direction, resulting in a net force of zero.

Front

What are unbalanced forces?

Back

Forces that are not equal and opposite, resulting in a net force that causes an object to accelerate.

Front

What is terminal velocity?

Back

The constant speed an object reaches when the force of gravity is balanced by the drag force of the medium through which it is moving.

Front

What is inertia?

Back

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

Front

How does mass affect inertia?

Back

The greater the mass of an object, the greater its inertia, making it harder to change its motion.

Front

What is the net force?

Back

The overall force acting on an object when all the individual forces are combined.

Front

What happens when the net force is zero?

Back

The object remains at rest or continues to move at a constant velocity.
