What tool is used to measure FORCE?

• triple beam balance

• spring scale

• meter stick

• none of these

How do you know you have a BALANCED force?

• it's stationary or moving at a constant speed

• a force causes a change in position

• the speed increases

Which of Newton's Laws is being described?
An object at rest remains at rest unless acted upon by a force and an object in motion remains in motion unless acted on by a force
ex. a ball on the floor

• Law of Inertia / Newton's 1st Law

• Law of acceleration / Newton's 2nd Law

• Action - Reaction/ Newton's 3rd Law
