SS Newton's 1st Law and FBDs

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

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

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

Why does an 18-wheeler have more inertia than a bicycle?

• it has more mass
• it has more volume
• it is not as aerodynamic

The sum of all forces acting on an object and direction

• Contact Force
• Balanced Force
• Unbalanced Force
• Net Force

Name the missing force...

• thrust
• buoyant force

Name the missing force...

• applied force
• weight force
• tension force
• drag
