If the net force on a object at rest is zero Newtons. What can you conclude?

• The object is in motion.

• The object is not in motion.

___________ forces always cause an object's motion to change.

• balanced

• unbalanced

• contact

• non-contact

______________ is a force that always acts in the direction opposite of motion.

• applied

• friction

• gravity

• normal

You are pulled to the surface of the earth due to the force of _________________

• gravity

• friction

• normal force

• contact force

If the forces acting on an object are balanced, they must:

• act in the same direction

• result in a net force of 0 N

• act in three different directions

• result in a net force greater than 0 N

If these teams are pulling with the same amount of force what will happen?

• The boy in blue will win.
• They will not move at all.
• The boy in red will win.
• Both will fall down.

With unbalanced forces, the object will move in the direction of the _______ force.

• larger 
• smaller 
• equal 

What is Newtons 1st law of motion?

• Force= Mass multiplied by acceleration 
• An object at rest stays at rest unless acted on an unbalanced force. (inertia)
• For every action there is a equal and opposite  re-action.
• law of gravity
