Newton's Laws of Motion Day 2

Front

What is Newton's First Law of Motion?

Back

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

Front

What is the term for forces that are equal in size and opposite in direction?

Back

Balanced forces.

Front

What does it mean if the net force acting on an object is zero?

Back

The object is either at rest or moving at a constant velocity.

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 the term for the tendency of an object to resist changes in its state of motion?

Back

Inertia.

Front

What is Newton's Third Law of Motion?

Back

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

Front

Give an example of Newton's First Law of Motion.

Back

A soccer ball will not move until a player kicks it.

Front

How does mass affect inertia?

Back

The greater the mass of an object, the greater its inertia.

Front

What is the formula for calculating force?

Back

Force (F) = mass (m) × acceleration (a).

Front

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

Back

It continues to move at a constant velocity.
