Newton's Three 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 happens to a soccer ball and a bowling ball when thrown with the same force?

Back

The soccer ball accelerates more than the bowling ball due to its lower mass, illustrating Newton's 2nd Law.

Front

What is a force?

Back

A force is a push or pull on an object resulting from its interaction with another object.

Front

What occurs to boxes in a truck that suddenly stops?

Back

The boxes will slide toward the front of the truck due to inertia, as described by Newton's 1st Law.

Front

What are balanced forces?

Back

Balanced forces are equal in size and opposite in direction, resulting in no change in motion.

Front

What are unbalanced forces?

Back

Unbalanced forces are not equal and can cause an object to accelerate or change direction.

Front

What is inertia?

Back

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

Front

How does mass affect acceleration according to Newton's 2nd Law?

Back

As mass increases, acceleration decreases for a given force.
