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

• Friction
• Mass
• Inertia
• Gravity

What is the standard unit force is measured in?

• N
• lbs
• g
• m/s

The tendency of an object to stay in motion or at rest is called 

• velocity
• acceleration
• speed
• inertia

All of these affect inertia except 

• size
• mass
• shape
• color

When two children of equal weight sit at opposite ends of a seesaw, they create

• gravity
• unbalanced forces
• motion
• balanced forces

Newtons 1st law of motion states:

• An object in motion will stay in motion and an object in rest will stay in rest unless acted upon by and unbalance force.
• For every action there is an equal and opposite reaction. 
• Acceleration is produced when a force. acts on a mass. 
• The greater the mass  the greater the amount of force needed to change its motion.
