Newton's First and Second Laws of Motion

The tendency of an object to resist a change in its state of motion is called the object's ______.

• incline
• straight line
• friction 
• inertia 

The ______of an object tends to make the object resist being set into motion.

• mass
• force
• motion
• unbalanced forces 

A pull or push that acts on an object is called a

• force
• motion
• mass
• momentum 

Without a force to stop or slow a coasting object, the object will coast forever in a ______ line. 

• blue
• red
• straight
• vertical 

_________ opposes the motion of one object moving past another. 

• friction 
• velocity
• unbalanced forces
• simple machines 

Objects at rest remain at rest and objects traveling at a steady rate in a straight line continue that way until a _________acts on them.  

• force
• velocity
• inertia
• acceleration 

A change in velocity, or the object position and speed.  

• speed
• acceleration
• momentum
• inertia 

The distance an object moves in a specific time. 

• velocity
• momentum
• speed
• simple machine 

The speed and direction of an object. 

• velocity
• heat
• energy
• convection 

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
