Newtons 3 Laws of Motion

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.

Front

Who formulated the Laws of Motion?

Back

Sir Isaac Newton.

Front

What is net force?

Back

The overall force acting on an object when all the individual forces are combined.

Front

If two forces of 5 N to the right and 5 N to the left act on an object, what is the net force?

Back

0 N (the forces cancel each other out).

Front

Which object has more inertia: a truck or a skateboard?

Back

A truck has more inertia because it has more mass.

Front

What does it mean if an object is in equilibrium?

Back

The net force acting on the object is zero, meaning it is either at rest or moving 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.
