NGSS.HS-PS2-1

the tendency of matter to resist changes in its motion.

• momentum
• inertia
• gravity
• friction

a pulling force that is that is transmitted through a rope, chain, or similar object.

• Compression
• Friction
• Gravity
• Tension

the force that acts in a direction that is perpendicular to the surface where 2 objects make contact.

• Normal force
• Centripetal force
• Frictional force
• Tangential force

the law that states that objects at rest remain at rest and objects in motion continue in a straight line at a constant velocity unless acted on by a net external force.

• Newton's Second Law of Motion

• Darwin's Theory of Evolution
• Newton's First Law of Motion
• Newton's Third Law of Motion

the law that states that the acceleration of an object is directly proportional to the net force acting on the object and is inversely proportional to its mass. F = ma

• Newton's second law of motion
• Newton's Third Law of Motion

• Boyle's law
• Newton's First Law Of motion
