What type of simple machine is found on the cap of a pickle jar?

Back

Screw: A type of simple machine that converts rotational motion into linear motion, often used to hold objects together or lift them.

Front

If a 16 N force is applied to an object and 96 J of work is done, how far was the object moved?

Back

6 m: Work is calculated using the formula Work = Force x Distance. Rearranging gives Distance = Work / Force.

Front

What are two examples of a pulley?

Back

Flagpole hoist and window blinds: Both use a pulley system to lift or lower objects.

Front

The force of gravity acting on an object is the object's ______.

Back

Weight: The measure of the gravitational force acting on an object, typically measured in newtons.

Front

The flag pole mechanism is an example of which simple machine?

Back

Pulley: A simple machine that consists of a wheel on an axle or shaft that is designed to support movement and change of direction of force.

Front

What is a lever?

Back

A lever is a simple machine that consists of a rigid bar that pivots around a fixed point called the fulcrum.

Front

What is the formula for calculating work?

Back

Work = Force x Distance: This formula shows that work is done when a force moves an object over a distance.

Front

What is an inclined plane?

Back

An inclined plane is a flat surface that is tilted at an angle to help raise or lower objects with less effort.

Front

What is the difference between mass and weight?

Back

Mass is the amount of matter in an object, while weight is the force of gravity acting on that mass.

Front

What is a wheel and axle?

Back

A wheel and axle is a simple machine consisting of a larger wheel attached to a smaller axle, allowing for easier movement.
