Newton's laws of motion

Gravity and Tension are both examples of contact forces.

• True

• False

All objects have inertia, whether they are moving or not.

• True

• False

• How are we suppose to know?

• Don't ask me

To change the motion of an object, inertia must be overcome by a __________ acting on the object.

• Temperature

• Force

• Net force

• Velocity

The tendency of an object to resist a change in its state of motion is called the object's ______.

• Mass

• Momentum

• Friction

• Inertia

Without a force to stop or slow a moving object, the object will move forever in a ______ .

• line

• curve

• straight line

• zig-zag line

Objects at rest remain at rest and objects traveling at a steady rate in a straight line continue that way until _________acts on them.

• a force

• balanced force

• momentum

• resultant force

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 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
