Substitute gravitational potential energy, mass, and free-fall ac-Section 2 acceleration answer key pdf download, section 2 acceleration answer key study guide and reinforce answers hanover area school , answer key chapter 1, the nature of science section 1 (p 1) 1 scientia 9 4 3 earth has more mass than the moon 4 no the moon exerts a smaller gravitational force than earth. 45 m/s2 7) 274 m/s2 8) 0. Gravity is a force that every object in the universe exerts on every other object. Predict: What do you think will happen when you release the balls from the exact same height? Answers will vary. Best Answer: Gravitational acceleration is more often called acceleration due to gravity, and is 9. 0 kg 6) 2. If its original speed is 8. 8 m/s^2? · Author has 440 answers and 758. 8 m/s squared down. If Earth's gravitational acceleration is 9. But as you go higher the gravitational acceleration is no longer g, but another number, let's say a. 16 kg 3) 1. To answer your 9. That means that, absent other forces, like air resistance (the friction caused by wind rushing past), an unsupported object will fall toward EARTH, accelerating by 9. Answer: Question 18 Back to Top. Use gc in Newton's 1st Law of Motion to answer this question. 2 times will vary with height by less than one part in a thousand. Gravitational Force gravitational acceleration, so a v R R TR M R M MM F HG I KJ 2 2 2 2 2S, 1 4S where R M 83. = 8 N (to the right) a = F net m. Again, from Newton's second law, the gravity force can be written as. 622 m/s2 Weight (W) = Mass (m) x gravity (g) W = mg Mass is measured in kilograms (kg) Gravity on earth is a constant: 9. What is the gravitational potential The value of gravitational acceleration of a body on Earth is 9. Here, m is the mass of the object, g is the acceleration due to gravity (9. Compare your answer to the value for the acceleration due to gravity ( 9,8 m · s -2)
