Newton's Laws Preassessment

Name given to the force that acts between materials that touch as they move past each other.

• Gravity

• Friction

• Air resistance

• Tension

The acceleration produced by a net force on an object is directly proportional to the magnitude of the net force and is inversely proportional to the mass of that object.

• Newton's First Law

• Newton's Second Law

• Newton's Third Law
