Questions with solutions
Q1 — Simple Machines · easy · theory
A simple machine helps us to ___.
A. Create new energy
B. Destroy energy
C. Stop all forces
D. Do work more easily ✓ Correct
Solution: Simple machines make our work easier; they do not create energy.
Q2 — Simple Machines · easy · theory
A seesaw in a park is an example of a ___.
A. Screw
B. Lever ✓ Correct
C. Wedge
D. Pulley
Solution: A seesaw turns about a fixed point in the middle, so it works as a lever.
Q3 — Simple Machines · easy · theory
A slanting ramp used to push a heavy box up onto a truck is an example of an ___.
A. Inclined plane ✓ Correct
B. Wheel and axle
C. Pulley
D. Lever
Solution: A ramp is a slanting flat surface, which is an inclined plane.
Q4 — Simple Machines · easy · theory
Which simple machine is commonly used to lift a bucket of water up from a well?
A. Wedge
B. Screw
C. Pulley ✓ Correct
D. Inclined plane
Solution: A pulley placed over the well lets us lift the bucket easily.
Q5 — Simple Machines · medium · theory
The sharp cutting edge of a knife or an axe works as a ___.
A. Screw
B. Wedge ✓ Correct
C. Lever
D. Pulley
Solution: A wedge has a sharp edge that is used to cut or split things.
Q6 — Simple Machines · medium · theory
The spiral threads on a bottle cap or a jar lid make it a kind of ___.
A. Lever
B. Pulley
C. Wedge
D. Screw ✓ Correct
Solution: The spiral threads make a bottle cap work like a screw.
Q7 — Simple Machines · medium · theory
The steering wheel of a car is an example of a ___.
A. Pulley
B. Wedge
C. Wheel and axle ✓ Correct
D. Inclined plane
Solution: A steering wheel turns on an axle, so it is a wheel and axle.
Q8 — Simple Machines · medium · theory
A pair of scissors is made mainly of two ___ joined together at a point.
A. Pulleys
B. Screws
C. Levers ✓ Correct
D. Ramps
Solution: Each handle of the scissors acts as a lever turning about the joint.
Q9 — Simple Machines · hard · theory
Why is it easier to move a heavy load up a ramp than to lift it straight up?
A. The ramp reduces the effort (force) needed ✓ Correct
B. The ramp removes gravity
C. The ramp adds energy to the load
D. The ramp makes the load weigh less
Solution: A ramp lets you use a smaller force over a longer distance, so less effort is needed. The weight of the load does not change.
Q10 — Simple Machines · hard · theory
Which of these is NOT a simple machine?
A. A pulley
B. An electric motor ✓ Correct
C. An inclined plane
D. A lever
Solution: An electric motor is a complex machine; a lever, pulley and inclined plane are simple machines.
