ABSTRACTSTo design a car with high efficiency by using alternative energy sources to achieve optimum performance.
OBJECTIVES
☺Reduce ,Reuse, and Recyclesolar energy is a renewable energy no pollutionenvironment friendly
☺Malaysia has abundant of sunlight throughout the year, car travel on land easy to get sunlight.
☺To spawn an alternative energy source to countries.
SCIENTIFIC THEORY
Sunlight energy
Electrical energy
Kinetic energy
INNOVATIONSCHOICE OF GEAR
Ratio of gear1:3
CHOICE OF BUILDING MATERIALS
CHOICE OF TYRESBig-if the perimeter of the tyres increases, the tyres travel more longer for one cycle.Light-reduce the total mass of the car,so the car can move faster.Thin-reduce the friction between the tyres and the surface.
MATERIALSGearUHU glueLolypop stickMotorSolar panelTyreWireShaft
CONSTRUCTION OF DESIGN
PROCEDURE1) Make car’s chassis.2) Solder solar panel.3) Connect solar panel to
motor.4) Combine the chassis, motor
and solar panel.5) Testing.
DISCUSSION1. Built of solar car: we managed to
built the solar car in firm structure .
2. Solar circuit - using series electric circuit and function well
- current : 0.5A - voltage : 1.0V - power : 0.5W3. Performance: the car moves
smoothly with good speed.4. Reduction of air resistance : The
friction is decreasing due to the aerodynamic design .
CONCLUSION
Solar energy can be used to move a car. Hence it can be used as an alternative energy
