What is a simple machine that does work with only one movement?

• Complex machine

• Simple machine

• Electric machine

• Hydraulic machine

What is the fixed point around which a lever pivots called?

• Input arm

• Output arm

• Fulcrum

• Lever point

What happens to the output force when the output arm is longer than the input arm?

• Output force > input force

• Output force < input force

• Output force = input force

• Output force is zero

If the output arm is shorter than the input arm, what is true about the output force?

• Output force > input force

• Output force < input force

• Output force = input force

• Output force is zero

What is the distance from the fulcrum to the point where the output force is exerted by the lever called?

• Input arm

• Output arm

• Fulcrum

• Lever arm

What is the formula for the ideal mechanical advantage (IMA) of a lever?

• IMA = L_out / L_in

• IMA = L_in + L_out

• IMA = L_in / L_out

• IMA = L_out - L_in
