Newton's 1st Law

What is Newton's First Law known as? The Law of

• Friction
• Mass
• Inertia
• Gravity

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 

The tendency of an object to resist a change in its motion

• acceleration
• inertia
• mass
• frame of reference

What kind(s) of objects have inertia?

• all objects with mass
• only objects at rest
• only objects in motion
• only objects whose motion is being changed

If one object has twice as much mass as another object, it also has twice as much...

• inertia
• velocity
• acceleration due to gravity
• DO NOT PUSH ME

Which type of force(s) will cause a change in an object's motion?

• gravity
• zero net force
• balanced forces
• unbalanced forces

The law of inertia (Newton’s First Law) applies

• to both moving and nonmoving objects
• only to moving objects
• only to objects that are not moving

Why is the net force 0 in the image?

• Because the elephants are the same size
• Because they are both pulling the same amount of force in opposite directions
• Because they are elephants
• Because they are pulling away from each other.
