1st Law of Motion

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

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 name for a push or pull?

• A movement
• A force
• Speed
• Density

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

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

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 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

• Truck
• Ant

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.
