Last class we worked on a battery powered car. We used gears to connect the motor to the wheels and experimented with different sizes of gears and wheels to increase its speed. When using a big gear on the motor and a small gear on the wheels, one rotation of the big gear will spin give the small gear multiple spins allowing our wheels to move faster for each turn the motor does. This took our cars to the next level with their speed!!! We all had a chance to try out our cars and race them. Looking forward to seeing you all next week!!!
