Newton's 1st Law of Motion

Newton's First Law of Motion is also known as

• The Law of Friction

• The Law of Mass

• The Law of Inertia

• Gravity

The definition of force is ______

• A movement

• a push or pull

• Speed

• Density

Newton's 1st Law states,________________________.

• 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

According to Newton’s first law of motion, an object at rest that is not acted on by an unbalanced force will

• remain in motion.
• eventually come to a stop.
• change its momentum.
• remain at rest

Why does an truck have more inertia than a bicycle?

• it has more mass

• it has more volume

• it is not as aerodynamic

What is Inertia?

• motion

• An object's resistance to motion

• friction
