An object in motion will stay in what kind of motion as long as the net forces acting on it are zero?

• slowing motion in a straight line
• accelerating motion in a straight line
• constant motion in a straight line
• constant motion in an unpredictable direction

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 the unit called that measures force?

• weight
• meter
• Newton
• kilogram

What is the net force acting on this box?

• 8N to the right

• 5N to the left

• 0N

• 6N to the left

What are the appropriate units to describe acceleration?

• m/s
• m/s²
• cm
• there are no units associated with acceleration

Which of these best states Newton's Second Law?

• The greater the mass of an object the greater the force needed to change its motion.

• The greater the mass of an object the less force needed to change its motion.

• The mass of an object does not effect the force needed to change its motion
