Newton's Laws

Front

What is a Newton?

Back

A Newton is a unit of force.

Front

What happens when an unbalanced force acts on an object?

Back

The force changes the motion of the object.

Front

What is Newton's 1st Law?

Back

An object at rest stays at rest, and an object in motion stays in motion unless acted upon by an unbalanced force.

Front

What is Newton's 2nd Law?

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?

Back

For every action, there is an equal and opposite reaction.

Front

What is an action force?

Back

An action force is the initial force applied to an object, such as pulling a bowstring.

Front

What is a reaction force?

Back

A reaction force is the force that occurs in response to an action force, such as the arrow flying forward when the bowstring is released.

Front

What is inertia?

Back

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

Front

What is net force?

Back

Net force is the total force acting on an object after all the forces are combined.

Front

How does mass affect acceleration?

Back

The greater the mass of an object, the less acceleration it will have for a given force.
