This practice test consists of everyday science MCQs about gravitation and its uses in our lives. Gravitation is one of the most important forces. It explains why things fall to the ground, like a ball or an apple and it keeps planets moving around the sun.
This test is perfect for students, job seekers or anyone who loves science. These everyday science MCQs are made to help you understand how science works in real life. You will learn about gravitation and its many uses in a fun and simple way.
