What is position?

• A change in an object's location

• An object's location

• The speed of an object

What describes motion?

• The ability to do work

• A change in an object's position

• A force acting on an object

What does speed measure?

• The distance an object travels

• How fast an object's position changes over time

What is force?

• The rate of energy transfer

• A push or pull

• The speed of an object

What are contact forces?

• Forces that act at a distance

• Forces that occur without touching

• Forces that occur as one object touches another

What are noncontact forces?

• Forces that can occur without objects touching

• Forces that require physical contact

• Forces that are always balanced

What defines balanced forces?

• Forces that change the motion of an object

• Forces that act on an object without changing its motion

• Forces that add up to a non-zero value

What are unbalanced forces?

• Forces that do not change an object's motion

• Forces that add up to zero

• Forces that change the motion of an object

What is inertia?

• The speed of an object

• The tendency of an object to resist changes in motion

• The force acting on an object

What is friction?

• A force that helps objects move

• A force that stops or slows down motion

• The speed of an object
