Newtons laws of motion

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 

Balanced force on an object cause the object to accelerate.

• True 
• False

F=MA
An object of mass 10 kg is accelerated upward at 2 m/s².  What force is required? 

• 20 N
• 2 N
• 5 N
• 0 N

Relating to Newton’s Third Law, action and reaction, what is the reaction when a rocket expels gas, smoke and flames from the nozzle end of the rocket engine?

• Nothing
• Propels in the opposite direction
• Creates a balanced force
• Creates friction

What is the name for a push or pull?

• A movement
• A force
• Speed
• Density

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

Which of Newtons laws explains why football teams have big, large, fast athletes.

• Frist and second
• second law
• first law
• Third law

The measure of the pull of gravity on an object is ___________________.

• motion
• weight
• speed
• friction

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 net force for this situation?

• 17 N Right
• 17 N Left
• 3 N Right
• 3 N Left
