Holt Physical Science Chapter 5: Matter in Motion Chapter Exam Question 1 If the gravitational pull of the sun is so strong, why are we not pulled off the Earth and into the sun? The earth rotates daily, which decreases the pull of the sun The gravitational pull of the sun is weakened due to the pull of other planets in the solar system The sun is too far away The mass of the sun is less than the mass of earth The sun's gravitational pull only affects objects on its surface Question 2 What law states that all objects in the universe are attracted to each other through the force of gravity? Law of Conservation of Gravity Boyle's Law Law of Universal Gravitation Isaac's Law Archimedes' Principle
Question 3 How can a moving object be in equilibrium? A force keeps it moving at constant velocity There is no change in the object's state of motion None are correct A moving object cannot be in equilibrium A force gets it moving Question 4 Why do we say that force is a vector quantity? It has magnitude only It has magnitude and direction Because forces can be balanced It has direction only Because forces can be unbalanced
Holt Physical Science Chapter 6: Forces and Motion Chapter Exam Question 1 The horizontal velocity of a projectile Will decrease as the object rises Will increase as the object falls Is only influenced by air resistance when the object is at its highest point Is influenced by air resistance Will remain the same throughout the entire motion Question 2 Before beginning projectile motion problems, you need to Solve for the acceleration due to gravity Split the projectile into mass and velocity vectors Split the horizontal motion and vertical motion Consider the impact of air resistance Determine the surface area of the projectile
Question 3 Which of the following is NOT considered a projectile motion problem?
