Newtons Law Practice

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

• Friction
• Mass
• Inertia
• Gravity

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

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

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

friction is a force that acts 

• in the same direction as the motion
• opposite to the direction of the motion
• opposite to the applied forces
• the same direction as the applied force

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 

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

• velocity
• gracitational acceleration
• inertia
• all of these

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

What is the net force of this object? 

• 10 N, no direction
• 10 N left
• 5 N right
• 0 N no direction
