Newton's 1st Law _____________________________. (select 2 answers)

• an object at rest will remain at rest unless acted upon by an unbalanced force

• an object in motion will remain in motion with constant velocity unless acted upon by an unbalanced force

• an object will change its motion only if a force is applied

• an object will always be in motion

The Law of Inertia is _________________.

• Newton's 1st Law

• Newton's 2nd Law

• Newton's 3rd Law

What is Inertia?

• Inertia is the ability of an object to change its state of motion easily
• an object's tendency to resist change in motion

• Inertia is the force that causes an object to move
• Inertia is the same as momentum
