• weight

• net force

• terminal velocity

NGSS.MS-PS2-4

tendency of an object to resist any change in its motion

• inertia

• gravity

• free fall

• terminal velocity

Newton's Law of Inertia describes the motion of-

• Objects at rest only
• Objects in motion only
• Objects at rest and objects that are in motion
• Objects without a mass and resist being set into motion

What is Newton's First Law

• F=ma

• Every action has an equal and opposite reaction

• An object at rest stays at rest, an object in motion stays in motion.

• Friction

Which one needs a greater net force to move, a kilogram of feathers or a kilogram of iron? 

• feathers 
• iron
• same
• depends on their friction

One object has twice as much mass as another object. The first object also has also twice as much...

• velocity
• gravitational acceleration
• inertia
• all of these

If a 10 kilogram object accelerates suddenly at 15 m/s², how much force was applied to the object?

• 150 Newtons
• 15 Newtons
• 150 kilograms
• 100 kilograms

When a large truck pushes a small car with a given force, the small car is applying an equal and opposite force on the truck.

• True
• False
