Have fun studying newtons second law (F=ma) with this spring loaded acceleration car. Simply pull it back and watch it go. The top cover is designed to be easily and quickly removed by taking out two screws underneath, allowing for greater acceleration. Additional mass can also be added with the top removed. A simple and inexpensive way to study Newton's 2nd law.
