Understanding Newton's First Law of Motion

How does inertia affect an object's motion?

How can Newton's first law be applied in real-life scenarios?

• In designing seat belts for cars

• In cooking recipes

• In gardening techniques

• In painting techniques

How does mass relate to force in Newton's first law?

• Mass and force are unrelated in Newton's first law

• Greater mass requires less force to change its motion

• Greater mass requires more force to change its motion

• Greater mass requires the same force to change its motion

According to Newton's first law of motion, what will objects do unless acted upon by an external force?

• Remain at rest

• Accelerate

• Change direction

• Disappear

Understanding this law helps engineers design safety features that protect individuals from sudden changes in (a)  

A force is defined as

• A push only

• A pull only

• A push or a pull

• None of the above

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

• incline
• straight line
• friction 
• inertia 

The ______of an object tends to make the object resist being set into motion.

• mass
• force
• motion
• unbalanced forces 

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.  

• force
• velocity
• inertia
• acceleration 

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
