Newton's 3 Laws of Motion

What is Newton's First law of Motion?

An object will remain at rest, or continue to move at constant velocity in the same direction unless a resultant force acts on it.

What is Newton's second law of motion?

Explains the proportional relationship between mass and acceleration- based on the formula F = ma.

What is the concept of inertial mass?

The greater the mass of an object, the larger the force required to change its velocity.

How do we calculate inertial mass?

Inertial mass = Force/ acceleration.

What is Newton's third law of motion?

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

What are action forces?

Action forces are forces that act on different objects.

Ex. A dog and a man pulling on a rope, there is an equilibrium on the rope causing it to remain still.

What are balanced forces?

Balanced forces are forces that act on the same object.

Ex: When the forward( thrust) and backward( drag) forces of a car are balanced, the object moves as constant speed.
