7. Why is it more difficult toonis fully loaded with parers than a car? The speed of the object with less massi Breater than the heavier one the speed of the object with greater mass is lesser than the heavier one. d. the speed of the object with greater mass is greater than the lighter one. 8. How distance between two objects affects the pull of gravity? a the lesser the distance, the lesser the gravitational pull between them. b. the greater the distance, the lesser the gravitational pull between them c. the greater the distance, the greater the gravitational pull between them. 9. You found one cart that is empty and one cart full of canned goods. Which cart will move faster if both were pushed with the same force? a. both carts b. neither of the cart c. cart which is empty tart full of canned goods 10. Which is true about mass and gravity? Ohone of these, gravitational pull between them depends on their weights, a. the lesser the mass of the object, the greater the pull of gravity b. the greater the mass of the object, the lesser the pull of gravity c. the greater the mass of the object, the greater the pull of gravity d. none of these, gravity and mass are not related 11. How can you say that something or someone is in motion? a, it has changed its position b. its position remains the same c. it does not move d. A, B and Care correct 12. What is the direction of the frictional force that acts on an object moving to the left? a, upward b. downward c. to the right c. to the left also Directions: Read the statement. Write True if the statement is correct and False if it is not. 13. The principle of gravity was discovered by Sir Isaac Newton. 14. Gravity is a contact force that acts between two separate objects. 15. Gravity keeps anything from going up. 16. Friction is the force that opposes the push of gravity on objects. 17. Gravity is the force exerted by the Earth which is equivalent to the mass of an object. 18. Gravity on the Moon is less than the gravity on the earth. 19. The lesser the mass of an object, the greater the pull of gravity on it. 20. Friction is a non-contact force.
