NGSS.3-PS2-2

A force that occurs when two objects are physically touching each other.

• Gravitational force
• Magnetic force
• Frictionless force
• Contact force

1. An object at rest stays at rest, and an object in motion stays in motion at the same speed and in the same direction unless acted upon by a net external force.
   
   

• Newton's Second Law of Motion
• Newton's Third Law of Motion
• Law of Universal Gravitation
• Newton's First Law of Motion

The acceleration of an object depends on the mass of the object and the amount of force applied, expressed as F = ma (Force = mass × acceleration).

• Mass is the only factor that determines acceleration.
• Newton's Second Law

• Force is equal to acceleration divided by mass.
• Acceleration is independent of the mass of the object.
