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

What is Newton's First Law

• F=ma
• Every action has an equal and opposite reaction
• An object at rest stays at rest, an object in motion stays in motion. 
• Friction 

An object following a straight-line path at a constant speed 

• has zero acceleration
• has no forces acting on it
• has a net force acting in the direction of motion
• none of these

A student is traveling to home from school on a commuter train at a constant speed in a straight line, which statement is true

• The driving force of the engine is bigger than friction and air resistance combined

• There are no forces acting on the bus

• The driving force of the engine is equal to friction and air resistance combined.

• A resultant force is required to keep the bus moving
