Exploring Motion and Energy Concepts DOL

Which of the following best describes Newton's First Law of Motion?

• An object in motion will eventually stop due to friction.

• An object at rest will stay at rest, and an object in motion will stay in motion unless acted upon by an external force.

• The force acting on an object is equal to the mass of the object times its acceleration.

• For every action, there is an equal and opposite reaction.

What is the term used to describe the resistance of an object to change its state of motion?

• Friction

• Gravity

• Inertia

• Momentum

What is thermal equilibrium?

• When two objects have the same mass

• When two objects are at the same temperature and no heat flows between them

• When two objects have the same volume

• When two objects are moving at the same speed

In a thermal system, when is equilibrium reached?
