  10. 10. KEMENTERIAN PELAJARAN MALAYSIA SMK AGAMA PAHANG MUADZAM SHAH • This car uses the photovoltaic panel that changes the solar energy to electric charge. • Solar cell are also called photovoltaic cell(pv cell) and can be found on many small appliances such as calculator and toys. • It occurs when the semiconductor material in the panel change the solar energy to electrical energy. • The panel will undergo a chemical reactions that will change the sunlight into electron. • This electron will rotate the motor and the wheels and make the car move TEAM IDENTITY ABSTRACT OBJECTIVE SCIENTIFIC THEORY INNOVATION DESIGN TRIAL RESULT

  14. 14. The circuit that are formed are the combination of a series and parallel circuit. Series circuit add power to the car while parallel circuit provide optimum energy for the car to move The calculation use to determine the power used is P =IV p is for power and to calculate power we must multiply current with voltage   
  15. 15. INNOVATION KEMENTERIAN PELAJARAN MALAYSIA SMK AGAMA PAHANG MUADZAM SHAH BODY : AERODYNAMICS   A shape that release the least resistance to the flow of the air. TEAM IDENTITY ABSTRACT  If the object was adjusted, the flow of the air around the object will smooth and cause less drag. OBJECTIVE SCIENTIFIC THEORY NEXT DESIGN TRIAL RESULT
  16. 16. INNOVATION   KEMENTERIAN PELAJARAN MALAYSIA SMK AGAMA PAHANG MUADZAM SHAH 1. DONWNFORCE Inverted wings to force the car down onto the rack, increasing traction. 2. BERNOULLI’S PRINCIPLE The lift generated by a wing is based on the principle that the pressure in a fluid decreases as its velocity increases (Bernoulli’s Principle). By creating just enough lift the car will be lighter as it moves, hence better chances in producing better speeds. TEAM IDENTITY ABSTRACT OBJECTIVE SCIENTIFIC THEORY NEXT DESIGN TRIAL RESULT We have applied this concept to our car.

  18. 18. KEMENTERIAN PELAJARAN MALAYSIA SMK AGAMA PAHANG MUADZAM SHAH Material TEAM IDENTITY ABSTRACT OBJECTIVE SCIENTIFIC THEORY NEXT DESIGN WE USE CORRUGATED BOARD AS THE MAIN MATERIAL TO MAKE THE BODY OF THE CAR BECAUSE IT IS LIGHT AND EASY TO SHAPE.WE ALSO USE SPAN TYRE TO MAKE THE CAR MOVE FASTER AND THE SOLAR PANEL TO SUPPLY ELECTRIC POWER TO THE MOTOR WHICH THEN ROTATE THE GEAR AND MAKE THE CAR MOVE TRIAL RESULT
  19. 19. KEMENTERIAN PELAJARAN MALAYSIA SMK AGAMA PAHANG MUADZAM SHAH TYRES TEAM IDENTITY ABSTRACT OBJECTIVE SCIENTIFIC THEORY NEXT WE USE THE SPAN TYRE BECAUSE IT IS LIGHT AND HAS LOW TRACTION WITH THE ROAD.THE LIGHT TYRE DOES NOT NEED TO MUCH FORCE TO ROTATE IT,MAKING IT EASY TO MOVE FASTER.

INNOVATION DESIGN TRIAL RESULT
  25. 25. DISCUSSION AND CONCLUSION KEMENTERIAN PELAJARAN MALAYSIA SMK AGAMA PAHANG MUADZAM SHAH DISCUSSION How should we get power from the motor to the wheels? Experiment with several different ways such as gears, pulleys, or some other method of drive, to get power to the wheels. What else should we think about as we design the car? Gears moving against each other The stretching or slipping of a belt The tires on the track All the other moving parts of the car CONCLUSION • THE SPEED OF THE CAR DEPENDS ON THE MATERIAL USED AS WELL AS THE BRIGHTNESS OF THE SUNLIGHT. • THE BRIGHTER THE SUNLIGHT,THE FASTER THE CAR WILL MOVE • THE LIGHTER THE MATERIAL USED,THE FASTER THE CAR WILL MOVE TEAM IDENTITY ABSTRACT OBJECTIVE SCIENTIFIC THEORY INNOVATION DESIGN TRIAL RESULT
