Newton's Laws of Motion - 12/2

Front

What is Newton's First 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 inertia?

Back

Inertia is the tendency of an object to resist changes in its state of motion.

Front

What does the term 'net force' refer to?

Back

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

Front

What is the direction of motion if the net force is 4N to the left?

Back

The object will move to the left.

Front

What is friction?

Back

Friction is a force that opposes the direction of motion of an object as it slides over a surface.

Front

What is Newton's Second 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 Third Law of Motion?

Back

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

Front

What is the Law of Universal Gravitation?

Back

Every point mass attracts every other point mass in the universe with a force that is directly proportional to the product of their masses and inversely proportional to the square of the distance between their centers.

Front

What happens to a book resting on a table when no external force is applied?

Back

It remains at rest due to Newton's First Law of Motion.

Front

What is the relationship between mass and inertia?

Back

The greater the mass of an object, the greater its inertia.
