Newton's Laws of Motion 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 inertia?

Back

Inertia is the tendency of an object to resist changes in its state of motion. The more mass an object has, the more inertia it has.

Front

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

Back

As mass increases, acceleration decreases if the same force is applied.

Front

What happens when a bowling ball strikes a bowling pin?

Back

The force applied by the bowling pin to the ball is equal to the force applied by the ball to the pin.

Front

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

Back

A magician pulling a tablecloth from under dishes without moving them demonstrates inertia.

Front

What does it mean when we say forces are equal and opposite?

Back

It means that when one object exerts a force on another, the second object exerts a force of equal strength in the opposite direction.

Front

What is the relationship between mass and inertia?

Back

Inertia increases with mass; heavier objects have more inertia.

Front

What is an example of Newton's 2nd Law in action?

Back

Pushing a child on a swing is easier than pushing an adult because the adult has more mass, requiring more force to achieve the same acceleration.
