TEK 8.6 Newton's Laws of Motion Review

Front

What is the tendency of an object to resist changes in its motion called?

Back

Inertia

Front

What does Newton's Third Law of Motion state?

Back

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

Front

How does mass affect the amount of force needed to move an object?

Back

As mass increases, the amount of force needed to move the object also increases.

Front

Why is the nozzle of a rocket pointed downward?

Back

The nozzle is pointed downward so that as fuel is combusted, the exhaust gases push downward, propelling the rocket upward due to Newton's Third Law.

Front

What force must the head of a hammer resist when driving nails?

Back

The force of the nail pushing in the opposite direction.

Front

Define Newton's First Law of Motion.

Back

An object at rest stays at rest, and an object in motion stays in motion at a constant velocity unless acted upon by a net external force.

Front

What is the relationship between force, mass, and acceleration according to Newton's Second Law of Motion?

Back

Force equals mass times acceleration (F = ma).

Front

What is an example of Newton's Third Law of Motion in everyday life?

Back

When you jump off a small boat, you push the boat backward as you move forward.

Front

What is the role of friction in motion?

Back

Friction opposes the motion of an object, affecting its acceleration and velocity.

Front

How does increasing the mass of an object affect its inertia?

Back

Increasing the mass of an object increases its inertia, making it harder to change its state of motion.
