Newton's Laws Practice

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 a net external 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.

Front

What is the role of friction in motion?

Back

Friction is a force that opposes the motion of an object, causing it to slow down or stop.

Front

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

Back

The object will continue in motion in a straight line at a constant speed.

Front

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

Back

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

Front

What is the relationship between action and reaction forces?

Back

Action and reaction forces are equal in magnitude and opposite in direction.

Front

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

Back

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

Front

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

Back

A heavier object requires more force to accelerate than a lighter object.
