As the mousetrap is released it pulls the string off of the axle causing the wheels to turn and making the car move. . The portion that sticks out will be the back of the car. The above procedure used rubber bands to provide traction; can you think of a better way? You can use a compass to draw these circles. Once your car is dry and the glue has set, securely tie the string to the bar of the spring arm.

Repeat the procedure for the rear end too. The snapper arm becomes the load, and the spring arm becomes the effort force moving the load. Traveled distances will be measured in a perpendicular path from the starting line to the finish line; Diagonal distances will not count toward the 5 meter required distance HotList: - Links that: 1. For this activity, you would want to have the same sized drive wheels on the back but you can print a variety of front wheels to see what their influence is on the behavior of the cars. The trap acts as a lever to transfer the energy to the axle. Mousetrap cars are frequently used to help students learn about mechanical advantage, distance, and gravity, with many teachers turning the experiment into a long distance challenge.

Both of these laws should show you that the more massive your car, the more force that will be required to move the car. You can put some electrical tape or rubber bands on the wheels, or you can opt for popped balloon rubber. Wind up the wheels and the rubber band by turning the wheels backward enough times so that the rubber band is tight. Take two eye screws and insert them at the corners of the rear end of the mousetrap. Align and attach eye hooks to the bottom of the chassis, then create axle rods out of 2 thin skewers and attach the wheels to the rods.

Obstacles may break the fragile design. The mousetrap car works on basic physic laws. Energy is commonly known as the ability to do work and the car has potential energy, which is the potential to do work. This project uses a standard household mousetrap to create a spring powered car. The spring may not be altered by further twisting. The dominant forces on the incline are gravity and the spring force, and by conservation of energy, the vertical distance traveled by the car can be approximated by equating the stored spring energy to the gravitational potential energy gained by the car.

Finally, attach them to the mousetrap car, and you are good to go. You can solve this problem by adding more traction to your rear wheels. Experiment often, and don’t be afraid to make mistakes. Your mousetrap car is now ready to race. Make sure the string is long enough for your purposes.

First, remove the loop and locking bar from the mousetrap car using your pliers. Make sure that the knot is tight. The two most important parts of a mousetrap car are the body frame and engine which will make the car move. Poke holes through each side of card to insert both sets of axles through and put wheels back on each end like a car. You can also use balloons. Instructions are included, but if you have.

For distance cars, larger wheels are best. Another, less thought of, friction involved in the performance of your car is air resistance. Add glue to the triangular key on the shaft and connect it to its mate after inserting it through the other collar. When the mousetrap spring is released, it turns the flywheel which then turns the drive wheel axle which propels the car forward. Use Newton's Third Law to describe action-reaction pairs, specifically using the tires and the floor as an example. When we learned that the first part of the project was focused on distance, we decided to build a sturdy but small wooden car that was fast and compact.

There are different variables to consider, making the mousetrap car a challenge to design. One way to try making the energy release slower is to lengthen the lever arm by attaching something pencil, dowel, etc. This should create holes that are slightly smaller than the dowel rods. It takes more force to accelerate a car with a large wheel-to-axle ratio, so smaller wheels will work better if you want your car to be fast. Operation of Mousetrap Car: There are a lot of physics and science concepts that demonstrate how the mousetrap car is able to move and compete in a jousting competition.

In a third-class lever, the load is at the end and the effort force is between the fulcrum and the load. Varying on the size of the drive wheel, students will be able to observe a difference in this translational distance which can be graphed and compared to the ratios between the wheel diameter and axle diameter. If you do not have a compass handy, you can use another round object. There is no lower limit on how small the drive wheels must be. But the coasting distance after V is reached will be roughly constant, so the biggest influence on distance traveled on a flat surface is how long it takes the car to gain speed. Do the same on the other side of the pen. Make sure to test it thoroughly.
