How can an apple pull the Earth toward it? * Apples are very strong and good for your health * All matter exerts the force of gravity on other matter * An apple cannot pull the Earth toward it, since it is so small2. Why does an object weight less on the Moon? * It has less mass on the Moon * There is no atmosphere on the Moon * The force of gravity is less on the Moon3. Why don't the planets fall into the Sun? * They have enough speed to keep them in orbit * They do, but we just don't notice it * The force of gravity pushes the planets away from the Sun***If you got all three correct, you are on your way to becoming a Champion in Physical Science. If you had problems, you had better look over the material again.</blockquote>
