#027 C4U Newton's Laws of Motion - Period 1

What is Newton's First Law

• F=ma

• An object at rest stays at rest, an object in motion stays in motion. 
• Friction

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

• incline
• straight line
• friction 
• inertia 

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

• unbalancing force

• velocity

• inertia

• balanced force

Forces that produce change in the motion of the object in the direction of the greatest force. 

• balanced forces 
• unbalance forces 
• incline
• Newton's

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

• Friction
• Mass
• Inertia
• Gravity

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

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
