ERHS Phys Sci Unit 10 - Newton's 1st & 2nd

The tendency of an object to resist change in motion.

• Force

• Motion

• Friction

• Inertia

Objects with more mass or are heavier have LESS inertia.

• True

• False

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

• stationary forces

• zero net force

• balanced forces

• unbalanced forces

What is the net force of this object?

• 10 N, no direction

• 10 N left

• 5 N right

• 0 N no direction

With unbalanced forces, the object will move in the direction of the _______ force.

• larger 
• smaller 
• equal

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

• force

• motion

• mass

• momentum

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 

What is the net force?

• 40 N left

• 0 N Balalnced

• 400 N right

• 40 N right
