The object is moving vertically. C. The object is moving downward. D. The only force acting on the object is the force of gravity. E. The only forces acting on the object are the forces of gravity and air resistance. F. The acceleration of the object is constant. G.An object is in freefall on Earth. Which of the following statements is true? A) The object is gaining an equal amount of momentum for each second it is in free fall. B) The object is gaining an equal amount of momentum for each meter it falls. C) The object is gaining an equal amount of kinetic energy for each meter it falls.Part A If an object is in free fall, which of the following statements must be true? Mark all the correct statements among those provided below. View Available Hint(s) O The initial velocity is zero. D The object is moving vertically 2 The object is moving downward G The only force acting on the object is the force of gravity The only forces acting on the object are the forces of gravity and air resistance.Free fall is the state of an object in which the only force acting upon it is the force of gravity. As the definition states, an object is in free fall if the only force acting upon the object is the force of gravity.As an object in free fall gets close to the ground, a person intervenes and slows it to rest. Which of the following statements is true about the magnitude of the acceleration of the object as it is stopped by the person? a) The acceleration must be equal to the acceleration due to gravity. b) The acceleration must be greater than the acceleration

Question on free fall. | Physics Forums

It refers to the acceleration of a free falling object. Evaluate this statement: A falling object accelerates at 9.8 m/s/s/s. This statement is only true of free-falling objects, upon which gravity is the only force of influence. Objects that are free-falling will ___________.A free-falling object is an object upon which the only force is gravity. As it falls, it accelerates at a rate of approx. 10 m/s/s. This acceleration value is constant during the entire trajectory of the motion. Since this is the case, the speed can not be constant.7. Which of the following statements is true? A. The object speeds up B. The object slows down C. The object moves with a constant velocity D. The object stays at rest E. The object is in free fall 8. What is the velocity of the object at 5 s? A. 1 m/s B. 2 m/s C. 3 m/s D. 4 m/s E. 5 m/s 9.following statements about this trip is correct? a. To average 50 mph the car must have exceeded 100 mph for at least 60 minutes of the trip. ~~ b. The instantaneous speed was never equal to 50 ~h during this trip. ~E'" c. You can never average 50 mph if the speed is zero for one half of the trip duration. FAM;:" d.

Question: Which one of the following statements is NOT true of a free-falling object? An object in a.i state of free fall a. falls with a constant speed of -10 m/s. O b. falls with a acceleration of -10 m/s/s. O c. falls under the sole influence of gravity. O d. falls with downward acceleration which has a constant magnitude. OAn object falling near the surface of the earth has a constant acceleration of 9.8 m/s2. This means that the a) object falls 9.8 m during the first second of its motion. b) object falls 9.8 m during each second of its motion. c) speed of the object increases by 9.8 m/s during each secod of its motion.7. Which of the following statements about free fall and the acceleration of gravity are TRUE? List all that apply. An object that is free-falling is acted upon by the force of gravity alone. A falling skydiver which has reached terminal velocity is considered to be in a state of free fall. A ball is thrown upwards and is rising towards its peak.A. Air resistance has a negligible effect upon the object B. Gravity is the only force acting upon the object C. The mass of the object does not effect the rate at which it free-falls D. The net force on the object is equal to mg E. The acceleration of the object is 0 m/s/s F. The velocity of the object is a constant value. G. None of these statements are true.For an object in free-fall (ignoring air resistance), which of the following statements is false: You are free to choose the origin and direction of the positive axis. The acceleration due to gravity is constant. The acceleration may point in the opposite direct as the velocity. The acceleration always points in the same direct as the velocity.
