Newton's Laws of Motion

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 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 definition of net force?

Back

The net force is the vector sum of all the forces acting on an object.

Front

What happens to an object when the net force acting on it is zero?

Back

The object remains at rest or continues to move at a constant velocity.

Front

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

Back

As mass increases, acceleration decreases for a given net force.

Front

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

Back

Force equals mass times acceleration (F=ma).

Front

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

Back

When you push against a wall, the wall pushes back with an equal and opposite force.

Front

What is inertia?

Back

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

Front

How does gravity affect the weight of an object?

Back

Weight is the force of gravity acting on an object's mass (Weight = mass x gravitational acceleration).
