newton laws of motion

If a force of 26 N is exerted on two balls, one with a mass of 0.52 kg and the other with a mass of 0.78 kg, which ball will have the greater acceleration?  (F=ma)

• The one with a mass of .78 kg will have the greatest acceleration.
• The one with a mass of .52 kg will have the greatest acceleration.
• They will both accelerate at the same rate.

A person steps out of the boat and onto the dock.  As the person moves forward onto the dock, the boat moves backward.  Which statement best describes the backward motion of the boat as the person steps forward?

• For every action there is an equal and opposite reaction.
• Every mass exerts a force on every other mass.
• An object at rest tends to stay at rest.
• Friction opposes the motion of an object.

When air rushes out of a balloon and it moves upward. This is an example of which Law of Motion. 

• Newton's First Law 
• Newton's Second Law 
• Newton's Third Law 

A person is pushed forward into their seatbelt when a car stops. Which of Newton's laws explains this motion?

• 1st law
•  2nd law
• 2 and 3 law
• 3rd law

Newton's 1st law is often called the _______.

• Newton's 2nd law
• action-reaction law
• law of equality
• law of inertia

Which has more Inertia? (and more force to move) 

• Truck
• Ant

Forces always act in equal and opposite pairs.

• Newton's 1st Law
• Newton's 3rd Law
• Newton's second law

Acceleration is caused by a force acting on a mass.

• Newton’s first law of motion
• Newton’s second law of motion
• Newton’s third law of motion

A sled sliding on a flat, icy surface with a constant velocity is best described by

• Newton’s first law of motion for objects at rest.
• Newton’s first law of motion for objects in motion.
• Newton’s second law of motion.
• Newton’s third law of motion.

According to Newton’s first law of motion, a moving object that is not acted on by an unbalanced force will

• remain in motion.
• eventually come to a stop.
• change its momentum.
• accelerate.
