Simple Machines
This simple machine is used to lift a load by applying a force at one point and receiving a mechanical advantage at another.
What is a lever?
This form of energy is stored in an object when it is elevated and has the potential to do work.
What is potential energy?
This law states that an object in motion stays in motion unless acted on by an external force.
What is Newton’s First Law of Motion?
This lightweight material is often used to build frames for Mission Possible devices because it is both strong and easy to manipulate.
What is wood?
The process of ensuring that your device doesn’t over-engineer or waste materials is known as this.
What is optimization?
This type of pulley allows you to change the direction of the force you apply.
What is a fixed pulley?
When a rubber band is stretched and released, it converts this type of energy into kinetic energy.
What is elastic potential energy?
A heavier object requires more of this to move at the same speed as a lighter object
What is force?
This common material is used for elastic components in devices, like springs.
What is rubber?
This factor can drastically change the performance of a machine, such as friction in a pulley or a gear system.
What is resistance?
A screw is a type of this simple machine, which is an inclined plane wrapped around a central shaft.
What is a helix?
A spring used in a Mission Possible device typically stores energy through this principle.
What is Hooke's Law?
The unit of force, which is also used to measure how much push or pull is applied in a Mission Possible device.
What is a Newton?
The process of joining materials together without the use of fasteners or adhesives, often using heat or pressure is called.
What is welding?
A good Mission Possible device often needs this for precision, like making sure it follows a path exactly.
What is accuracy?
This is the device that uses a rope or cable to lift heavy loads, typically with a mechanical advantage.
What is a pulley system?
This energy form is associated with object motion and is used to perform work, such as when a car moves.
What is kinetic energy?
When two surfaces rub against each other, this force works to slow things down.
What is friction?
This material is durable, often used for pulleys or gears, and is great for transferring force in mechanical systems.
What is metal?
This is the principle behind using gravity to move an object in many Mission Possible devices.
What is gravitational potential energy?
This simple machine reduces the force needed to move an object up by increasing the distance over which the force is applied.
What is an inclined plane?
This term refers to energy conversion efficiency, which is crucial in Mission Possible devices to avoid unnecessary energy losses.
What is energy efficiency?
This principle explains how you can balance forces in a system to keep an object stationary.
What is the principle of equilibrium?
The mechanical advantage gained by using this material in a gear system can be enhanced with its specific texture and design.
What is plastic?
When troubleshooting your device, you would likely focus on testing the forces at play, such as tension in strings or this force in the spring.
What is force or tension?
