Newton's Laws of Motion 2022

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 the Law of Inertia?

Back

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

Front

What are unbalanced forces?

Back

Forces that cause an object to accelerate or decelerate, resulting in a change in motion.

Front

What is the effect of balanced forces on an object?

Back

Balanced forces do not change the motion of an object; the object remains at rest or continues to move at a constant velocity.

Front

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

Back

As mass increases, acceleration decreases for a given force; heavier objects require more force to accelerate.

Front

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

Back

A passenger lurching forward in a car when it suddenly stops.

Front

What is the relationship between force, mass, and acceleration?

Back

Force equals mass times acceleration (F=ma), indicating that greater force results in greater acceleration.

Front

What happens to an object in motion when no net force acts on it?

Back

It continues to move at a constant velocity.
