Newton's 1st Law

What is Newton's First Law of Motion?

• F=m x a
• Every action has an equal and opposite reaction
• An object at rest stays at rest, an object in motion stays in motion unless acted on by another force. 
• Friction 

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

• Friction
• Mass
• Inertia
• Gravity

What is inertia?

• the force that opposes motion
• the force of attraction between 2 objects
• an object's tendency to stay in motion or to stay at rest
• a change in an object's speed and/or direction

• zero net force
• balanced forces
• unbalanced forces

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

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

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 18-wheeler have more inertia than a bicycle?

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

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
