Overview of DesignOverview of Design

Design Overview To lift the 1 kg weight, we used a

counter weight system on tracks. The weight is attached to the string.

It begins at the top of the design, and is released by a trigger which lets the weight fall.

The weight should fall, but also pull up the weight as it reaches the bottom of the design.

Types of EnergyTypes of Energy Potential energyPotential energy can be thought of as energy stored within a can be thought of as energy stored within a

physical system. This energy can be released or converted into physical system. This energy can be released or converted into other forms of energy, including kinetic energy. It has the other forms of energy, including kinetic energy. It has the potential to change the states of objects in the system when the potential to change the states of objects in the system when the energy is released.energy is released.

Kinetic Energy- The Kinetic Energy- The kinetic energykinetic energy of an object is the extra of an object is the extra energy which it possesses due to its motion. It is defined as energy which it possesses due to its motion. It is defined as the the work needed to accelerate a body of a given mass from rest to its work needed to accelerate a body of a given mass from rest to its current velocitycurrent velocity. .

ConclusionConclusion The project overall was a success as the team worked well The project overall was a success as the team worked well

together and designed a successful model. Through this together and designed a successful model. Through this project, we applied the basic concepts of physics including project, we applied the basic concepts of physics including the concepts of potential kinetic energy, as well as energy the concepts of potential kinetic energy, as well as energy motion. The project involved some complications as the motion. The project involved some complications as the first design was not successful, but working as a team, we first design was not successful, but working as a team, we designed a new machine that was more balanced and was designed a new machine that was more balanced and was able to complete the task more successfully. Although the able to complete the task more successfully. Although the project involved a little problems, it was a success in terms project involved a little problems, it was a success in terms of its structure and its design.of its structure and its design.
