Simple Machines Quiz

What is the function of a lever in simple machines?

• To help lift objects that are difficult to pick up

• To make objects heavier

• To increase the speed of an object

• To change the color of an object

What is the role of the fulcrum in a lever?

• It acts as a counterweight

• It decreases the weight of the object

• It increases the length of the lever

• It provides a pivot point for the lever

How does an inclined plane make moving objects easier?

• By making objects move faster

• By reducing the effort needed to lift objects

• By providing a smoother surface

• By increasing the weight of the object

What is a wheel and axle in simple machines?

• A wheel with a rod through the middle that spins together

• A wheel that is fixed and does not rotate

• A wheel that moves independently of the axle

• A rod that moves without a wheel

Why does an object move further when placed on a wheel and axle?

• Because it is lighter

• Because it is pushed harder

• Because the wheel and axle reduce friction

• Because it becomes heavier
