Task Lists 13 - 15 (Newton's Laws of Motion)

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 Unit do we Measure Force in? 

• Newtons
• Joules
• Force
• Don't know

What is the net force on this box?

• 10 N to the right
• 10 N to the left
• 90 N to the left
• 290 N to the left

What is the name for a push or pull?

• A movement
• A force
• Speed
• Density

According to Newton's first law, an object in motion will stay in what kind of motion as long as the net forces acting on it are zero?

• slowing motion in a straight line
• accelerating motion in a straight line
• constant motion in a straight line
• constant motion in an unpredictable direction

What is the net force of this object? 

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

Find the net force: 15 N to the right, and another 15 newtons to the right.

• 0 N Right
• 0 N Left
• 30 N Left
• 30 N Right

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

• larger 
• smaller 
• equal 

Forces that have a net force of zero ( the object is still).

• Balanced force
• Unbalanced force

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
